Abstract
- Hydrous hydrazine has received increasing attention as a promising hydrogen carrier owing to its many favorable attributes, such as high hydrogen content, low material cost, stable liquid state at ambient conditions, and free of solid decomposition byproduct. Herein, we report the synthesis of a supported core–shell structured Ni@Ni–Pt/La 2 O 3 catalyst by a combination of co-precipitation and galvanic replacement methods. The catalyst exhibits high catalytic activity and 100% selectivity towards hydrogen generation from hydrous hydrazine at mild conditions, which outperforms most reported hydrous hydrazine decomposition catalysts. The favorable catalytic performance of the Ni@Ni–Pt/La 2 O 3 catalyst is correlated with the Pt-induced electronic and geometric modifications on the catalyst surface. [ABSTRACT FROM AUTHOR]
