Description
Technical Field
The invention relates to an application of a strontium-doped molybdenum sulfide material in self-powered piezoelectrically enhanced hydrogen production, in particular to an application of the strontium-doped molybdenum sulfide material in photocatalytic self-powered piezoelectrically enhanced hydrogen production, and belongs to the field of new energy.
Background
With the rapid development of human society, people's demand for energy is increasing day by day, and the exhaustion of fossil fuel causes energy shortage. Hydrogen energy is widely concerned by people because of its advantages of high combustion value, no secondary pollution and the like. However, hydrogen is easy to explode, and the cost of compressing hydrogen is high, so how to safely, effectively and economically prepare hydrogen and use hydrogen is a technical problem to be solved by hydrogen energy and hydrogen economy. Ammonia borane (NH)3BH3) The hydrogen storage material is a main hydrogen storage material, has the hydrogen content of 19.6 wt%, is solid at normal temperature and normal pressure, has higher stability, is safe and nontoxic, and is easy to carry. Thus, NH in contrast to gaseous or liquid hydrogen3BH3Is considered a more efficient and safer way of storing hydrogen energy. However, NH3BH3Hydrogen is released very slowly under natural conditions. In order to rapidly release hydrogen, catalysts containing noble metals, such as platinum, palladium, rhodium, gold, etc., have been developed. However, noble metals are expensive and low in abundance, so their applications are very limited. There is a need to develop a new technology that is safe, economical, environmentally friendly, and capable of releasing hydrogen gas efficiently.
The piezoelectric material has the characteristic of converting mechanical energy into electric energy, so that mechanical vibration energy of an automobile in running can be absorbed, and self-powered hydrogen production is realized.

Further, the mechanical energy may be generated by vibration, noise, ultrasonic waves, stirring, etc. applied to the hydrogen production reaction system.
The embodiment of the invention also provides a self-powered piezoelectric enhanced photocatalytic hydrogen production method, which comprises the following steps:

The reaction mechanism of the photocatalytic hydrogen production provided by the invention is that NH is carried out in the presence of a proper catalyst3BH3Hydrogen may be released by solvolysis or thermal decomposition, as follows:
NH3BH3(aq)+2H2O(l)＝NH4 +(aq)+BO2 -(aq)+3H2(g) (as shown in FIG. 5)
In the present invention, molybdenum sulfide itself is a semiconductor material that can respond to near infrared light and has a piezoelectric effect. The catalyst has three catalytic paths, the first is the thermal catalysis of the catalyst, which reduces the reaction potential of ammonia borane and water and accelerates the reaction rate. The second one is photocatalysis in response to 850nm near infrared light, electron transition occurs when the material is radiated by 850nm near infrared light, and photo-generated electrons react with protons h + in water to generate hydrogen. Since the electronegativity of H in the system is higher than that of B, H attracts free electrons to form hydride H-. Photoproduction of holes with hydride H-The combination produces hydrogen. The third is that the catalyst generates piezoelectric effect in ultrasonic oscillation, and self-establishing electric field is formed inside the material to make electronsMoving directionally, producing electrons and protons H in water+Reacting to generate hydrogen, generating positive hole and negative hydrogen ion H-The combination produces hydrogen. After strontium is doped into molybdenum sulfide, the forbidden bandwidth of the material is narrowed from the aspect of photocatalysis, the theoretical absorption boundary of the material is widened, and the utilization efficiency of light is improved. And the defects of the material are increased after doping, so that the recombination of electrons and holes is reduced, and the photocatalytic efficiency of the material is improved. From the aspect of piezoelectric catalysis, the surface defects of the material are increased, so that the entropy and the chaos of the material are increased, and the bulk defects of the material are increased, so that the symmetry of the material is reduced. The reduction of symmetry enhances the piezoelectric effect of the material, effectively inhibits the recombination of electrons and holes, and improves the piezoelectric catalysis efficiency of the material. In conclusion, the doping of strontium improves the photocatalytic hydrogen production activity of molybdenum sulfide.
