New progress has been made in the research of hydrazine decomposition to hydrogen production in Dalian Institute of Chemical Technology

Researchers Huang Yanqiang and Academician Zhang Tao of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences have received extensive attention from international counterparts in the research of hydrazine decomposition and hydrogen production.
They have recently been invited to publish a review article in the National Science Review
.
Hydrazine (N2H4) is an important liquid propellant, which can be rapidly decomposed at room temperature under the action of a catalyst to produce high-temperature and high-pressure gas and realize the conversion of chemical energy to kinetic energy
.
Researchers have been committed to the basic and applied research of hydrazine decomposition reaction for a long time, and developed a variety of hydrazine decomposition catalysts for various application fields of the national economy
.
The realization of the selective regulation of hydrazine decomposition (highly selective generation of hydrogen and nitrogen) has clear application value and is the focus of academic attention.
The core is to realize its ability to break NN bonds and NH bonds through optimized design of the catalyst , And precise control of the sequence
.
This article focuses on the team’s strategy for regulating the activity and selectivity of hydrogen production from hydrazine decomposition on non-precious metal nickel-based catalysts.
The use of alkaline promoter effects, alloy effects and strong metal-support interactions have constructed supported types of different structures.
The nickel-based catalyst system realizes the high activity and high selective decomposition of hydrazine to produce hydrogen
.
Related research work has further deepened the understanding of the mechanism of hydrazine decomposition reaction and laid an important foundation for the application of hydrazine decomposition catalysts in China in key areas
.
