Abstract

The invention provides a non-noble metal catalyst used for N2H4BH3 complete hydrogen production, and a preparation method thereof. The non-noble metal catalyst is composed of non-noble metal copper, nickel, and molybdenum, and is prepared via simple and effective one-step reduction. According to the preparation method, sodium borohydride is taken as a reducing agent, and the non-noble metal catalyst is obtained via direct reduction of a mixed solution composed of a copper source, a nickel source, and a molybdenum source precursor at different ratio. The non-noble metal catalyst can be used for high efficiency catalyzing of boryl hydrolysis and hydrazino cracking of N2H4BH3 at 323K alkaline environment so as to realize complete hydrogen production, the transformation frequency (TOF) value is capable of reaching 108mol H2 mol metal<-1>h<-1>. The non-noble metal catalyst is simple to prepare, is low in cost, possesses high catalytic activity and stability, and is promising in development prospect.

Description

technical field

[0001] The method of the invention relates to a non-noble metal catalyst, in particular to a non-noble metal catalyst used for the complete hydrogen production of hydrazine borane and a preparation method thereof, belonging to the field of hydrogen storage materials.

[0002] technical background

[0003] With the increasing energy crisis and environmental pollution, the development of new low-carbon clean energy is imminent. Hydrogen energy has attracted much attention as a clean, efficient, safe and pollution-free energy source. The utilization of hydrogen energy mainly includes the cheap production of hydrogen, safe and efficient hydrogen storage and large-scale application. However, the problem of safe and efficient storage of hydrogen has always been the bottleneck restricting the development and utilization of hydrogen energy. High-capacity solid hydrogen storage materials with high hydrogen storage mass fraction and volumetric hydrogen storage density ...
