Exactly regulated copper catalysts exploiting isolated photoelectrochemical reduction of cuprous oxides and random mesh-structured TiO2 for enhanced photoelectrochemical CO2 conversion

This work presents a novel photocorrosion paradigm to guide CO 2 RR photocathode design. The isolated photoelectrochemical reduction corrosion (IPRC) method developed through this artificial control provides an efficient route to ensure long-term stability, energy saving, and high performance.
