Embodiment 1

[0034]

[0035] Above-mentioned composite material is played by the preparation method of following steps:

[0036] Graphene oxide was synthesized by a modified Hummer method. Ferric nitrate nonahydrate and ammonium molybdate were made into a 0.2M solution, sodium sulfide was made into a 1M solution, and then graphene oxide was ultrasonically dissolved in 8ml of DMF, and ferric nitrate, ammonium molybdate and sodium sulfide were added to the solution. Stir at 90°C for 24 hours, then cool, centrifuge, and wash with distilled water three times to remove unreacted raw materials. Then add DMF solution and heat it in a hydrothermal kettle for 5-10 hours, then centrifuge, wash with distilled water for 3 times, and finally freeze-dry at -70°C to obtain Fe 2-1.5x Mo x S 2 -RGO hybrid catalyst.

Abstract

The invention relates to a Fe2-1.5xMoxS2-RGO hybrid catalyst and a preparation method and application thereof. According to the Fe2-1.5xMoxS2-RGO, nano particles are loaded on graphene oxide, then hydrothermal reaction is carried out, vulcanizing is carried out at high temperature and high pressure, and a part of the graphene oxide is reduced to generate the Fe2-1.5xMoxS2-RGO. The preparation method comprises the steps of the preparation of the graphene oxide and the preparation of the Fe2-1.5xMoxS2-RGO. Compared with the prior art, the cost of obtained Fe2-1.5xMoxS2-RGO hybrid catalyst is lower than that of an existing electrocatalyst, the hybrid catalyst can be used for electrocatalytic hydrogen evolution, doping of a Mo element reduces the over-potential in the electrocatalytic hydrogenevolution process, and the electrocatalytic hydrogen evolution effect is improved; and the stability of the catalyst is good, the preparation method is simple, the performance of the electrocatalytichydrogen evolution is enhanced, and the method can be used for industrial development.

Description

[0001] [Technical field] [0002] The invention relates to the technical field of hydrogen energy, in particular to a Fe 2-1.5x Mo x S 2 -RGO hybrid catalyst and its preparation method and application. [0003] [Background technique] [0004] The rapid development of society and economy will inevitably lead to the increasing depletion of fossil resources and serious environmental pollution. The development of renewable and clean energy is of great significance to promoting the sustainable development of society and economy. Hydrogen has the advantages of high calorific value of combustion, diverse storage and transportation methods, and abundant raw materials for preparation, and is considered to be an ideal energy carrier. For example, by converting renewable clean energy into hydrogen, and then using hydrogen as fuel for fuel cells to generate clean electricity, this can not only solve the contradiction between the supply and use of renewable clean energy, but also allevia...
