Huang Yanqiang, a researcher at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, and Zhang Tao, an academician of the Chinese Academy of Sciences, have received extensive attention from international counterparts in the work of decomposing hydrogen production. Recently, they were invited to present in the National Science Review entitled Design strategies. Of highly selective nickel catalysts for H2 production via hydrous hydrazine decomposition: a review of review articles.
Niobium (N2H4) is an important liquid propellant that can be rapidly decomposed at room temperature under the action of a catalyst to produce high temperature and high pressure gas, which can transform chemical energy into kinetic energy. The team has long been committed to the basis of decomposing reactions. Applied research, developed a variety of antimony decomposition catalysts for various application fields of the national economy. The realization of the regulation of the decomposing selectivity (highly selective hydrogen and nitrogen generation) has clear application value and is the focus of academic circles. The core lies in the optimization of the catalyst to achieve its ability to break the NN bond and NH bond, as well as the precise control of the sequence. This article focuses on the team's regulation of hydrogen production and selectivity on the non-precious metal nickel-based catalyst. Strategy: Using the alkaline builder effect (Angew. Chem. Int. Ed., AIChE J.), alloy effect (Appl. Catal. B, J. Catal.) and metal-carrier strong interaction (ACS Catal.), The supported nickel-based catalyst system with different structures was constructed to achieve high activity and high selective decomposition of hydrogen. The related research work further deepened the understanding of the mechanism of ruthenium decomposition reaction. Catalyst in key areas of the country hydrazine decomposition laid an important foundation.
The above work has been funded by the National Natural Science Foundation of China and related projects of the Chinese Academy of Sciences.
