Amorphous Boron Carbide on Titanium Dioxide Nanobelt Arrays for High‐Efficiency Electrocatalytic NO Reduction to NH₃

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(18)

Published: Feb. 25, 2022

Electrocatalytic NO reduction is regarded as an attractive strategy to degrade the contaminant into useful NH3 , but lack of efficient and stable electrocatalysts facilitate such multiple proton-coupled electron-transfer processes impedes its applications. Here, we report on developing amorphous B2.6 C supported a TiO2 nanoarray Ti plate (a-B2.6 C@TiO2 /Ti) -producing nanocatalyst with appreciable activity durability toward electroreduction. It shows yield 3678.6 μg h-1 cm-2 FE 87.6 %, superior /Ti (563.5 42.6 %) a-B2.6 C/Ti (2499.2 85.6 %). An /Ti-based Zn-NO battery achieves power density 1.7 mW 1125 . in-depth understanding catalytic mechanisms gained by theoretical calculations.

Recent advances in interface engineering strategy for highly‐efficient electrocatalytic water splitting

InfoMat, Journal Year: 2022, Volume and Issue: 5(1)

Published: Oct. 13, 2022

Abstract The hydrogen energy generated by the electrocatalytic water splitting reaction has been established as a renewable and clean carrier with ultra‐high density, which can well make up for shortcomings of conventional sources, such geographical limitations, climatic dependence, wastage. Notably, introduction electrocatalysts enhance efficiency process to generate hydrogen. Particularly, heterostructure constructed coupling multiple components (or phases) have emerged most promising option due well‐known electronic synergistic effects. existing reviews on interface engineering electrocatalyst design mostly focus relationship between heterostructures specific reactions. However, comprehensive overview integration model building, directional synthesis, mechanism rarely reported. To this end, in review, development catalysts is systematically introduced from perspective classification, growth regulation performance based interfacial microenvironment (bonding, configuration, lattice strain, etc.), thereby offering useful insights construction models. Besides, combined current applications strategies, challenges future are discussed relevant solutions proposed. Overall, review serve theoretical reference mechanism, further promote production technologies low consumption high yield. image

P and Mo Dual Doped Ru Ultrasmall Nanoclusters Embedded in P‐Doped Porous Carbon toward Efficient Hydrogen Evolution Reaction

Advanced Energy Materials, Journal Year: 2022, Volume and Issue: 12(23)

Published: April 22, 2022

Abstract Rational design of efficient hydrogen evolution reaction (HER) electrocatalysts for mass production via electrochemical water splitting is a challenging but pressing task. Herein, an in situ dual doping engineering from phosphomolybdic acid encapsulated within the bimetallic metal‐organic‐frameworks strategy to synthesize P,Mo doped Ru ultrasmall nanoparticles embedded P‐doped porous carbon (P,Mo‐Ru@PC) HER proposed. As result, P,Mo‐Ru@PC achieves low overpotential 21 at 10 mA cm −2 , Tafel slopes 21.7 mV dec −1 and activity about 22 times greater than that commercial 20 wt% Pt/C alkaline media. First principle calculations demonstrate introducing Mo P atoms into lattices triggers electron donation consequently reduces energy barrier HER.
