A quaternary heterojunction nanoflower for significantly enhanced electrochemical water splitting

Abstract

Designing highly-efficient, cost-effective, and stable electrocatalysts for water splitting is essential to produce green hydrogen. In this work, a nanoflower quaternary heterostructured Ni(NO3)2(OH)4/Ni(OH)2/Ni3S2/NiFe-LDH electrocatalyst is successfully synthesized by two-step hydrothermal...

Simultaneously Improving Energy Storage and Oxygen Evolution Reaction by Causing Regional Defects in MOF-on-MOF Derived Hollow Se-Doped CoP-Fe2P Heterojunctions

“…3 Yet, the efficiency of hydrogen production during electrolysis is limited by the slow four-electron transfer process in the anodic oxygen evolution reaction (OER). 4 Materials such as RuO 2 and IrO 2 are considered as the most effective electrocatalysts. Particularly, RuO 2 is the first reported electrode material with pseudocapacitive behavior, combining energy storage and catalytic functionalities.…”
