High-energy Charge Separation State for Photocatalytic Nonoxidative Methane Conversion

Abstract: The nonoxidative coupling of methane (NOCM) under mild conditions is a promising technique for low-cost H2 and carbon feedstock productions. Here, we fabricate a Ce-Zr solid solution photocatalyst containing nonstoichiometric CeO2 − x nano-islands with stepped surfaces and abundant oxygen vacancies, enabling unprecedented adsorption of methane and ideal for the photocatalytic NOCM at room temperature. It is revealed that the Ce-Zr photocatalyst can undergo a cooperative and reversible photo-induced transition … Show more
