CuO/SnO Heterostructures: Role of the Synthesis Procedure on PEC CO Conversion.

Addressing the urgent need to mitigate increasing levels of CO in the atmosphere and combat global warming, the development of earth-abundant catalysts for selective photo-electrochemical CO conversion is a central and pressing challenge. Toward this purpose, two synthetic strategies for obtaining a CuO-SnO catalyst, namely co-precipitation and core-shell methods, were compared. The morphology and band gap energy of the synthesized materials were strongly different.
