Ultrastable and highly efficient hydrogen evolution by heterogeneous NiO/Ni catalysts under industrial electrolysis conditions

Abstract

The heterojunction of NiO/Ni synergistically optimizes the kinetics during the alkaline hydrogen evolution process, thereby enhancing the catalytic performance beyond that of Pt/C.

Design and multilevel regulation of transition metal phosphides for efficient and industrial water electrolysis

“…147 Under industrial electrolysis conditions, the current density and time span are much larger than in laboratory tests, which puts forward higher requirements on the stability of the catalyst. 124,148,149 Long-term high load operation is more likely to lead to catalyst deactivation. The pollution and failure of ion exchange membranes and electrolytes in electrolytic cells may affect the performance of catalysts.…”
