Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

Carbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

Bulk and Surface Magnetization of Co atoms in Rutile Ti_[1-x]Co_xO_[2-delta] Thin Films Revealed by X-Ray Magnetic Circular Dichroism

, 2011
We have studied magnetism in Ti_[1-x]Co_xO_[2-\delta] thin films with various x and \delta by soft x-ray magnetic circular dichroism (XMCD) measurements at the Co L_[2,3] absorption edges. The estimated ferromagnetic moment by XMCD was 0.15-0.24 \mu\beta/

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).

β‐Scission of Tertiary Alcohols on a Platinum‐Loaded Titanium Dioxide Photocatalyst for C─C Bond‐Forming Reactions

Chemistry – A European Journal, EarlyView.
A strategy for the Pt/TiO2‐photocatalyzed β‐scission of nonactivated 3° alcohols in the absence of external oxidants and additives was developed. A wide variety of C‐centered radicals were generated and subsequently engaged in C─C bond‐forming reactions.

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

Chemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...
