Preparation of NiPt/Ti₂O₃ nanocatalyst and its catalytic performance for hydrogen production from hydrazine hydrate

Hydrazine hydrate is the most promising hydrogen storage material with a hydrogen content of 8.0%. In this paper, after Ti₂O₃ support was prepared by H₂ reduction, NiPt/Ti₂O₃ nanocatalyst was prepared by wet chemistry impregnation reduction method and used to catalyze hydrazine hydrate. The research shows that an alloy is formed between Ni and Pt during the preparation of the catalyst, and the formation of the alloy increases the catalytic activity of the catalyst. The interaction between Ti₂O₃ and NiPt alloy is helpful for the catalytic performance and cyclic stability of the catalyst. The TOF value of the Ni₅Pt₅/Ti₂O₃ catalyst for hydrogen production from hydrazine hydrate is 1076.1 h⁻¹, which is superior to the reported catalyst performance.
