Tunable Coordination Number in Non‐Metal‐Introduced Copper Catalysts Enables High‐Performance Electrochemical CO2 Reduction to C2 Products

open access: yesAdvanced Functional Materials, EarlyView.
Copper catalysts introduced with different non‐metallic elements regulating the coordination number of Cu are prepared by magnetron sputtering. Reducing the Cu coordination number enhances C─C coupling and boosts C2+ product selectivity, by lowering the energy barrier for the *CO → *CHO conversion step. The optimized Si‐doped Cu catalyst achieves a C2+

Room-Temperature Fabrication of Electrocatalyst for Oxygen Reduction Using Pt Nanoparticle-dispersed Protic Ionic Liquid with Poly(3,4-ethylenedioxythiophene)

open access: yesElectrochemistry, 2021
Mixing of a Pt-sputtered protic ionic liquid (PIL) containing 3,4-ethylenedioxythiophene and a carbon support at room temperature for 3 min produces carbon-supported Pt nanoparticles (Pt-NPs), in which the PIL acts as an adhesive.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...
