Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis
Advanced Science, EarlyView.A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

Complex Electrooxidation of Formic Acid on Palladium
Journal of the Brazilian Chemical Society, 2014 Herein, oscillatory formic acid (FA) electrooxidation on polycrystalline palladium is investigated and compared with the one on polycrystalline platinum; major differences between both are attributed to differences on the kinetics of sub-set chemical network as well as to preferential routes admitted on palladium surface. To presume the kinetic rate of

Nanoporous gold catalyst for direct ammonia borane fuel cells [PDF]
, 2013 Nanoporous gold (NPG) electrodes were fabricated in film and wire array formats by selectively dealloying Ag from Au0.18Ag0.82. The ammonia borane (AB) oxidation reaction was studied by cyclic voltammetry at the NPG electrodes.

Advanced Science, EarlyView.This work presents an internal‐external synergy strategy where a C@FeNi2Se4 core‐shell precursor reconstructes in to a C/FeNi2Se4/SeO42− architecture during OER. The inner C stabilizes active sites while the outer SeO42− layer repels Cl−, achieving efficient and stable seawater oxidation for over 150 h at 400 mA cm−2.
