Highly Efficient Biomass Upgrading by a Ni−Cu Electrocatalyst Featuring Passivation of Water Oxidation Activity

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(37)

Published: July 24, 2023

Abstract Electricity‐driven organo‐oxidations have shown an increasing potential recently. However, oxygen evolution reaction (OER) is the primary competitive reaction, especially under high current densities, which leads to low Faradaic efficiency (FE) of product and catalyst detachment from electrode. Here, we report a bimetallic Ni−Cu electrocatalyst supported on Ni foam (Ni−Cu/NF) passivate OER process while oxidation 5‐hydroxymethylfurfural (HMF) significantly enhanced. A density 1000 mA cm −2 can be achieved at 1.50 V vs . reversible hydrogen electrode, both FE yield keep close 100 % over wide range potentials. Both experimental results theoretical calculations reveal that Cu doping impedes OH* deprotonation O* hereby greatly passivated. Those instructive provide new approach realizing highly efficient biomass upgrading by regulating activity.

Recent Advances in Hybrid Seawater Electrolysis for Hydrogen Production

Advanced Materials, Journal Year: 2023, Volume and Issue: 36(13)

Published: Dec. 24, 2023

Abstract Seawater electrolysis (SWE) is a promising and potentially cost‐effective approach to hydrogen production, considering that seawater vastly abundant SWE able combine with offshore renewables producing green hydrogen. However, has long been suffering from technical challenges including the high energy demand interference of chlorine chemistry, leading electrolyzers low efficiency short lifespan. In this context, hybrid SWE, operated by replacing energy‐demanding oxygen evolution reaction interfering (CER) thermodynamically more favorable anodic oxidation (AOR) or designing innovative electrolyzer cells, recently emerged as better alternative, which not only allows occur in safe energy‐saving manner without notorious CER, but also enables co‐production value‐added chemicals elimination environmental pollutants. This review provides first account recent advances for production. The substitutional AOR various small molecules redox mediators, couple seawater, comprehensively summarized. Moreover, how cell design helps briefly discussed. Last, current future outlook about development technology are outlined.
