Description
Technical Field
The invention relates to the technical field of green energy material manufacturing, in particular to an oxide spherical photonic crystal with an inverse opal structure, a simple preparation method and application thereof.
Background
Photonic crystals are a class of artificially designed and manufactured crystals with periodic dielectric structures on the optical scale, which have photonic band gap characteristics that prohibit the propagation of certain specific frequencies of incident light in the photonic crystal structure. If the frequency of the incident light falls within the photonic band gap, the incident light is severely inhibited from propagating in the photonic crystal structure, i.e., the photonic crystal structure may have a reflectivity of up to 100% for incident light within the passband, and may propagate with little loss. Photonic bandgaps show a strong reflection of incident light in a certain band by photonic crystals in the upper part of the spectrum, photons at the edges of the bandgap, i.e. at the edges of the reflection peaks, have extremely low group velocities, so-called slow photons. The reflection of incident light by the photonic crystal structure follows the law of bragg diffraction, and the slow photon effect can be studied by adjusting parameters such as the aperture size, the angle of incident light, the filling rate, the refractive index of the filler and the like of the photonic crystal structure according to the bragg equation shown below.
The inverse protein structure is a typical photonic crystal, has the characteristics of easy adjustment of pore size, filling rate and refractive index of the filler, and has the advantages of ordered structure height, adjustable size, adjustable pore size, large specific surface area and the like. However, the conventional powder or film products have the problem that slow photon effects only occur at specific angles, namely, angle dependence, due to the change of the incident angle in the catalysis process, so that the development of the slow photon effects is limited. The spherical photonic crystal has a fully symmetrical structure, is not influenced by the angle of incident light, and therefore has more stable performance.
At present, the method for preparing the photonic crystal with the spherical inverse opal structure comprises the following steps: spray drying, electric field driving and microfluidics. However, the use of spray-drying methods that require specialized instrumentation for the microfluidic spray-dryer limits its application; the electric field driving method has the advantages that the obtained size is in millimeter level, the size cannot be regulated and controlled, and the yield is low; the microfluidic method relies heavily on a part of a microfluidic chip, the microfluidic chip made of glass is fragile, and due to the limitation of a glass preparation process, microspheres with smaller sizes cannot be obtained, and the size adjustment of the microfluidic chip is limited, and the chip made of polydimethylsiloxane is firm and durable, but most of organic solvents are soluble in polydimethylsiloxane and swell, and small organic analytes with obvious solubility in water are also soluble in polydimethylsiloxane, so that the use of the microfluidic chip is limited.
In addition, due to the characteristics of the materials, the preparation methods of different materials are different, and no simple method can prepare spherical photonic crystals of various oxides.
Disclosure of Invention
In order to solve the problems, the oxide spherical photonic crystal with the inverse opal structure can be simply prepared by using an emulsion shear polymerization method.
The specific technical scheme is as follows:
The first aspect of the present invention is to provide a simple preparation method of an oxide spherical photonic crystal of inverse opal structure, having such characteristics that it comprises the steps of:
1) Preparing a monodisperse negatively charged template;
2) Preparing an oxide spherical photonic crystal with an inverse opal structure: mixing template solution, precursor and ethanol, sucking the mixture into an injector after ultrasonic mixing, mounting the injector on a driver, connecting a catheter on a needle of the injector, inserting the tail end of the catheter into rotating collecting oil, driving the injector by a propeller, injecting feed liquid in the injector into the collecting oil, continuously stirring, drying water, collecting microspheres, calcining to remove the template, and thus obtaining the oxide spherical photonic crystal with inverse opal structure.
The simple preparation method also has the characteristic that the solid content in the template solution in the step 1) is 5-30%.
The simple preparation method also has the characteristic that the volume ratio of the template solution, the precursor and the ethanol in the step (2) is (1-3.3) (1-3).
The simple preparation method also has the characteristic that the feed liquid advancing speed in the step (2) is 0.1-15mL/h.
The simple preparation method also has the characteristics that the viscosity of the collected oil in the step (2) is more than or equal to 10cst, and the rotating speed of the collected oil is 100-6000r/min.
The simple preparation method also has the characteristics that the drying temperature of the oven in the step (2) is 50-55 ℃, the drying time is 12-48h, and the calcining temperature is 550-700 ℃.
The second aspect of the present invention is to provide an oxide spherical photonic crystal of inverse opal structure prepared according to the above-described simple preparation method.
The third aspect of the invention is to provide an application of the oxide spherical photonic crystal with the inverse opal structure in photocatalytic hydrogen production.
It should be noted that, the template in the invention may be a negatively charged polymer microsphere or a silica microsphere; the precursor is a hydrolyzable substance or a feed liquid (solid content is 0.1-3%) containing small-particle oxide, which is prepared from a hydrolyzable salt solution, and for a metal salt with severe hydrolysis conditions, the feed liquid containing small-particle oxide can be prepared as the precursor.
The template with negative electricity and the hydrolysis particles with negative electricity which are generated by partial hydrolysis and alcoholysis are mutually repelled, so that the whole system is in dynamic balance, water and ethanol are gradually evaporated along with the drying process, the charges on the surfaces of the template and the precursor are gradually reduced, at the moment, the energy of the system needs to be kept to be minimum, the template pellets are gradually close to form a sphere under the action of capillary suction pipe force, the precursor is further hydrolyzed on the surfaces of the template pellets to form crystal nuclei in the process, the crystal nuclei are further grown and grown through hydrolysis, and finally the oxide spherical photonic crystal with the inverse opal structure can be obtained after the template pellets are removed by calcination.
The beneficial effect of above-mentioned scheme is:
1) According to the preparation method, a continuous aqueous phase emulsion is formed by adopting an injector, spherical liquid drops with a small-size water-in-oil structure are obtained by collecting the shearing force of oil liquid, the follow-up rotation can be used for preventing the liquid drops from being recombined, the rotation speed is regulated and controlled to control the evaporation speed of water so as to regulate and control the hydrolysis degree of a precursor, and meanwhile, the photonic crystal microsphere is obtained by means of the capillary force of the polymer microsphere in the aqueous phase;
2) The oxide spherical photonic crystal microsphere with the inverse opal structure prepared by the preparation method has the advantages of complete symmetry, ordered arrangement height, good repeatability, adjustable size and high yield;
3) The spherical photonic crystal prepared by the invention has the inverse opal structure, and the structure not only has the advantages of large specific surface area, more surface active sites and the like, but also solves the problem that the general photonic crystal material has angle dependence, so that the photocatalysis performance is more stable;
4) The oxide spherical photonic crystal prepared by the invention is composed of nano oxide particles, has a plurality of surface active sites and higher photocatalytic performance, and can effectively promote the separation of photogenerated carriers, improve the rate of electron transmission and improve the utilization rate of sunlight;
5) The spherical oxide photonic crystal prepared by the method is applicable to various hydrolyzable oxides and small-particle oxides which can be prepared, so that the universality of the method is greatly improved.
