Scalable H2O2 Production via O2 Reduction Using Immobilized Vanadyl Phthalocyanine

Angewandte Chemie, EarlyView.
Electrochemical H2O2 production via 2e⁻ ORR is a green alternative to the emission‐heavy anthraquinone process, but selectivity at practical current remains low. We develop a vanadium catalyst composite achieving >90% H₂O₂ selectivity at 3.5 A cm−2 in acid.

Decoding Double Layer Dynamics for CO2${\rm CO}_2$ Electroreduction over Cu

Angewandte Chemie International Edition, EarlyView.
Different regions of the electrode/electrolyte interface, such as the interfacial layer and diffuse double layer, are spectroscopically discerned by analyzing multi‐dimensional time‐variance within a matrix of time‐resolved infrared spectra. In this way, discrete events relating to reorientation of water molecules in the double layer are elucidated ...

Self‐optimizing Cobalt Tungsten Oxide Electrocatalysts toward Enhanced Oxygen Evolution in Alkaline Media

Angewandte Chemie International Edition, EarlyView.
Progressively enhanced oxygen evolution is achieved by self‐optimization of cobalt tungsten oxide deposited on lab‐synthesized copper oxide substrate. Experimental data proved dynamic compositional / structural evolution while theoretical calculation revealed active site adaptation.

Interfacial Photoelectrochemistry in Organic Synthesis

Angewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.

Mechanistic Promiscuity in Cobalt Mediated CO2 Reduction Reaction: One‐ versus Two‐Electron Reduction Process

Angewandte Chemie International Edition, Accepted Article.
We compare the carbon dioxide reduction (CO2RR) activity and selectivity of the complexes [(Hbbpya)CoII]2+ and [(Mebbpya)CoII]2+, which contain two 2,2′‐bipyridine chelating groups linked by ‐NH or ‐NCH3 moieties, respectively. Whereas [(Hbbpya)CoII]2+ forms CO under electrocatalytic conditions in presence of phenol (PhOH) with high selectivity ...
