Oxygen Evolution Reaction by Ni‐Hexacyanoferrates Nanocubes Integrated with Trigonal Selenium: Effect, Properties and Performances

open access: yesAdvanced Functional Materials, EarlyView.
This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Engineering Oxygen Vacancy in Support to Promote Activity of In2O3 Catalyst for CO2 Electroreduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach by depositing In2O3 onto an oxygen vacancy (OV)‐enriched support, ceria‐zirconia solid solutions (CZ), to activate synergistic effects is proposed. The OV contributes greatly to the dissociation of H2O and further promotes the hydrogenation of adsorbed CO2 species.
