Efficient hydrogen production with controlled hydrochloric acid addition using Ni-based catalyst synthesized in ethanol solvent

Preparation of highly efficient NiB catalyst via triton‐stabilized for alkaline NaBH 4 hydrolysis reaction

“…The interaction between Ni particles and ethanol solution produced these crystalline structures. The use of alcohol as solvent has also been reported to have significant effects on the synthesized materials' crystal growth, phase formation and particle agglomeration 40,49 . Based on the Scherrer equation ( D hkl = ( kλ )/( β cos θ hkl )), the peak at 44.20° for NiB25 becomes broader and this increase in the full half‐length of diffraction peak indicates a decrease in the particle size.…”

Non-noble metal catalysts for preventing chlorine evolution reaction in electrolytic seawater splitting

“…[45][46][47] In addition, most of the highly selective Ni-based metal materials are only suitable for direct electrolytic seawater splitting under alkaline conditions. [48][49][50][51] Besides, the prepared negative anode materials may undergo cracking if they are energized for a long time under industrial high currents. [52][53][54] In recent years, scholars have started to design a variety of anode catalysts to solve a series of problems due to the competition between the OER and CER in seawater splitting.…”
