Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Formic‐Acid In Situ Hydrogen Enables Programmable Ru–Pd–Pt/C Trimetallic Interfaces for Durable Acidic HER

Carbon Energy, EarlyView.
Bamboo diaphragm−derived carbon is used as a support to prepare Ru–Pd–Pt/C catalysts through a stepwise reduction strategy. The Ru–Pd interface promotes formic acid activation and induces Pt deposition. The metallic interface of Ru–Pd–Pt/C enables H* generation, transfer, and recombination, thereby improving Pt utilization, acidic HER activity, and PEM

Ru Nanoparticle Supported by Mesoporous SiOx and Pillared Montmorillonite: Suppressing Catalyst Inhibition in Carbon Dioxide Hydrogenation

Chemistry – A European Journal, EarlyView.
Ru nanoparticles confined within mesoporous SiOx‐pillared montmorillonite exhibit exceptional performance for CO2 methanation. The catalyst maintains a high reaction rate even at elevated CO2 conversion while preserving high Ru mass–specific activity, overcoming typical inhibition by H2O and CO observed in conventional supported Ru catalysts.

Countercation Manipulation Enables Selective Electrochemical CO2‐to‐Formate Conversion Over Bi‐Polyoxometalate‐Derived Catalysts

Chemistry – A European Journal, EarlyView.
Ba2+ salt of Bi‐incorporated polyoxometalate (POM), Bi4 ([Bi4O(γ‐SiW10O36)2(OAc)]7−), immobilized on a carbon support (Ba‐Bi4/C) functioned as a formate (HCOO−)‐selective catalyst for electrochemical CO2 reduction reaction (CO2RR). The incorporation of Ba2+ and the formation of highly dispersed Bi species were the key factors for Ba‐Bi4/C to achieve ...

Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

EcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...
