Hydrogen Migration Enhances Proton‐Coupled Electron Transfer in an S‐Scheme Heterojunction for High‐Efficiency Photocatalysis

Carbon Energy, EarlyView.
Precisely directed built‐in electric field in an S‐scheme heterojunction synergizes photogenerated charge separation with interfacial proton migration, thus co‐localizing electrons and protons on the NOH surface and boosting proton‐coupled electron transfer kinetics in the rate‐determining hydrogen release step. ABSTRACT The kinetic bottleneck in solar‐

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

Chemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

EcoEnergy, EarlyView.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...
