Controllable fabrication of iron–nickel alloy embedded in nitrogen-doped carbon for oxygen evolution

Abstract

Due to the low activity and poor stability of pure Ni-based OER electrocatalysts, an FeNi alloy is wrapped by an amino-modified MOF-5-derived N-doped carbon layer to address the disadvantages.

Activating nickel foam with trace titanium oxide for enhanced water oxidation

“…To address these problems, additional metals or metal oxide semiconductors are incorporated as dopants or substrates, respectively. 5–8 TiO 2 , a low-cost yet interesting semiconductor, is frequently employed as the substrate due to its robust stability under high oxidation conditions. 9–12 TiO 2 with single and/or nano crystallization and oxygen vacancies has promoted surface reconstruction for the generation of high-valence Ni species.…”
