Abstract

The invention provides an application of a nickel-doped molybdenum sulfide material in self-energized piezoelectric enhanced hydrogen production. The nickel-doped molybdenum sulfide material (Ni-MoS2)comprises a molybdenum sulfide MoS2 material with response to near-infrared light and divalent nickel ions doped in molybdenum sulfide and on the surface of molybdenum sulfide. The nickel-doped molybdenum sulfide material provided by the invention can effectively utilize natural mechanical energy (such as vibration, noise, ultrasonic wave, stirring and the like), takes ammonia borane with the hydrogen content as high as 19.6 wt% as a hydrogen storage material to prepare hydrogen energy at normal temperature and normal pressure, and realizes self-energized piezoelectric enhanced hydrogen production. The hydrogen fuel can be prepared and used at any time, and the problem that hydrogen is not easy to store is solved. The preparation method of the nickel-doped molybdenum sulfide material provided by the invention is simple, feasible, green and environment-friendly.

Description

technical field [0001] The invention relates to the application of a nickel-doped molybdenum sulfide material in self-powered piezoelectric enhanced hydrogen production, in particular to the application of nickel-doped molybdenum sulfide material in photocatalytic self-powered piezoelectric enhanced hydrogen production, which belongs to the field of new energy. Background technique [0002] With the rapid development of human society, people's demand for energy is increasing, and the depletion of fossil fuels has caused energy shortages. Hydrogen energy has attracted widespread attention because of its high combustion value and no secondary pollution. However, hydrogen is prone to explosion, and the cost of compressing hydrogen is relatively high. Therefore, how to produce and use hydrogen safely, effectively and economically has always been a technical problem to be solved for hydrogen energy and hydrogen economy. Ammoniaborane (NH 3 BH 3 ) is a main hydrogen storage mat...
