FeCoP Sub-Nanosheets for Electrocatalytic Water Splitting

The use of renewable energy for water electrolysis can achieve a green hydrogen production industry chain. However, finding efficient electrocatalysts remains a challenge for green hydrogen production. Here, we constructed sub-nanoscale FeCoP nanosheets with an average thickness of 0.9 nanometers through ultrasonic cavitation-driven two-dimensional self-assembly, followed by phosphorization treatment. Benefiting from rich active sites, enhanced … Read more

Enhancing Electrocatalytic CO2 Reduction to Formic Acid Using In2O3@C and Graphene Nanocomposites

Indium oxide (In₂O₃) is an effective electrocatalyst for converting carbon dioxide (CO₂) to formic acid (HCOOH), but its inherent poor conductivity limits the effective charge transfer during the reaction process. Additionally, the aggregation of indium oxide particles during synthesis further restricts the exposure of active sites. This study addresses these issues by utilizing the template … Read more

Amorphous Mixed Tungsten Oxide-Nickel Hydroxide Nanosheets for Efficient Hydrogen Evolution

For alkaline hydrogen evolution reaction (HER), there are more challenges in simultaneously accelerating the electron coupling hydrolysis process (Volmer step) and the subsequent electrochemical H2 desorption (Heyrovsky step). Due to the bifunctionality of mixed amorphous electrocatalysts on different fundamental steps of HER, and the optimal interaction with water molecules and reactive hydrogen intermediates (Had), it … Read more
