Titanosilicate ETS-10-Modified Cu2O for Enhanced Visible-Light Photoelectrochemical Activity
Original language description
Copper(I) oxide (Cu(2)O)-based photocathodes are promising materials for carbon dioxide (CO2) reduction under visible light due to copper's abundance and favorable energy band alignment. However, Cu(2)O suffers from photocorrosion and chemical instability. Here, we present a novel approach utilizing a porous titanosilicate material (ETS-10) as a protective layer for Cu(2)O, addressing these limitations. The Cu(2)O was electrodeposited and coated with a thin ETS-10 layer, which prevents photocorrosion, enhances charge separation and transfer, and facilitates CO2 capture through its highly porous structure. Comprehensive structural, compositional, and morphological analyses confirmed that ETS-10 effectively stabilized Cu(2)O while maintaining its electronic properties (UV-Vis, XPS). The Cu(2)O/ETS-10 photocathode exhibited a 25% enhancement in the photocurrent density at 0.0-0.1 V vs. RHE and significantly improved stability compared to bare Cu(2)O. The thin ETS-10 layer acted as a passivation layer, improving charge transfer via tunneling mechanisms. This study introduces a multicomponent photocathode system, demonstrating a new application of ETS-10 in photoelectrochemical cells. The results highlight the potential of ETS-10 to enhance the efficiency and stability of photocathodes, offering a pathway for the design of advanced systems for solar-driven CO2 reduction and artificial photosynthesis.
