Nickel Hydroxide Catalyzed Bias‐free Photoelectrochemical NH3 Production via Nitrate Reduction

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical nitrate reduction reaction with high efficiency and production rate is achieved using a crystalline silicon photocathode with nickel as the catalyst. Performing the PEC NO3RR under alkaline conditions can be self‐activated of the Ni surface by forming Ni(OH)2.

Bias‐Free Solar Upcycling of Nitrate and Glycerol with Highly Efficient and Durable Organic Semiconductor‐Based Photoelectrodes

open access: yesAdvanced Materials, EarlyView.
A bias‐free photoelectrochemical (PEC) upcycling system integrating bi‐functional nickel‐iron‐phosphorus (Ni‐Fe‐P) catalysts with organic semiconductor (OS)‐based dual photoelectrodes is reported. The system enables simultaneous solar‐driven conversion of nitrate to ammonia and glycerol to formic acid with high efficiency and stability.
