Facile Fabrication of NiPt/CNTs as an Efficient Catalyst for Hydrogen Production from Hydrous Hydrazine

Hydrogen generation through catalytically hydrous hydrazine has recently emerged as a promising strategy to meet the ever-increasing demand for sustainable energy. However, it remains a challenging obstacle to design highly active catalysts as well as low-cost. In this work, we designed a series of NiPt/CNTs catalysts, which were prepared via a facile wet chemical reduction method, employed it in the dehydrogenation of hydrous hydrazine. The crystalline structure, chemical states and morphology of the catalysts were also characterized in detail. Among these catalysts, Ni0.4Pt0.6/CNTs exhibits highest activity with a turnover frequency (TOF) of 1725.3 h(-1) at 50 degrees C and a low E-a of 36.3 kJ/mol. Considering its cost-effective and high performance, the Ni0.4Pt0.6/CNTs represent a promising catalyst to hydrolyze hydrous hydrazine for hydrogen generation.
