The invention relates to a preparation method of a special explosive for catalyst doping, which adopts an electric explosion method to detonate the special explosive so as to complete the doping. Compared with the prior art, the invention has the beneficial effects that: 1) various metals can be doped into the catalyst, 2) a large number of cavities can be produced, and 3) the carbonization step is omitted, thereby saving energy.
Description
Technical Field
The invention relates to a preparation method of a special explosive for doping a catalyst, which utilizes a method of explosion and even explosion to dope required elements into common MOF materials.
Background
MOFs are an emerging material that is widely used in various fields. For example, the common MOF material ZIF-8 is synthesized by using zinc nitrate 2-methylimidazole, which has good electrocatalytic performance, but cannot meet the requirement due to the limitation of only one metal element, and needs to be doped, such as iron element, cobalt element, nickel element and the like. The doping is usually performed by soaking, but the doping effect is general, and it takes a lot of time and medicine, which does not meet the current theme of green chemistry. Almost all disputes in the present generation are the main problem of surrounding energy, and the adoption of a novel catalyst to decompose water into hydrogen is a promising route, but a single metal element cannot meet the requirement generally due to the uniqueness of the performance, and at the moment, doping is needed. The doping is carried out by adopting a deflagration and even explosion mode, so that required elements can be doped, most of carbonization steps of the catalyst are saved, energy is greatly saved, and a large amount of time is saved.
Disclosure of Invention
For most catalysts, the required elements are doped, so that a large amount of energy is required, and the elements are not easily doped, for example, iron element is doped, iron hydroxide colloid is easily generated, and the iron element cannot be well doped, but some elements which are difficult to dope can be easily doped by adopting a deflagration and explosion method. The technical scheme adopted by the invention is as follows: a preparation method of a special explosive for doping a catalyst is characterized by comprising the following steps:
synthesis of common MOF materials, e.g., ZIF-8, ZIF-67, and the like
Obtaining nitrate with crystal water removed, grinding and sieving, wherein the nitrate is cobalt nitrate, nickel nitrate and the like, dissolving the nitrate in ethanol, drying at 80 ℃ to obtain hydrochloride with crystal water removed, submerging and sieving to obtain nitrate powder with grain size less than 500 meshes, adding high-energy explosive to adjust the temperature
Adding sulfur and carbon powder
Adding metal powder with particle size less than 500 meshes
Weighing a certain amount of common MOF material, nitrate, high-energy explosive, sulfur, carbon powder and metal powder, uniformly mixing the materials, and sieving to obtain mixed powder with the particle size of less than 500 meshes.
Putting the mixed powder into a vacuum device, detonating the mixed powder by adopting an exploder, and collecting a product, wherein the exploder is an MFB-100 type exploder produced by a large stone bridge explosion-proof electrical appliance factory in Leqing, the peak value of the output voltage of the exploder is 1800V, and the rated load resistance of the exploder is 620 omega
Washing with 1M hydrochloric acid, washing with deionized water for three times, and oven drying at 60 deg.C.
Has the advantages that:
compared with the prior art, the invention has the beneficial effects that: not only can doping elements which are difficult to dope into the catalyst, but also can save a large amount of energy and time.
