The rational design of an S‐scheme heterojunctions in hybrid semiconductors to realize separated charge carriers and sufficient redox ability is considered as an attractive way to achieve high photocatalytic activity in diluted CO2 reduction (DCR). An S‐scheme heterojunction formed in the fibrous Ta2O5/Ag2S nanostructures is proposed for improving the photocatalytic performance in DCR under simulated...
Carbon Dot Electrocatalysts
In article number 2303156, Zhendong Lei, Zheng Liu, Liang Wang, and co‐workers establish an innovative and scalable solvent engineering strategy to fabricate oxygen‐doped carbon dots, resulting in an exceptional electrocatalysis H2O2 productivity yield of 111.18 mg h−1 cm−2 in a flow cell for a duration of 10 hours.
The development of cost‐effective and reliable metal‐free carbon‐based electrocatalysts has gained significant attention for electrochemical hydrogen peroxide (H2O2) generation through a two‐electron oxygen reduction reaction. In this study, a scalable solvent engineering strategy is employed to fabricate oxygen‐doped carbon dots (O‐CDs) that exhibit excellent performance as electrocatalysts. By adjusting...
