In Situ Generation of HO over MoO Decorated on CuO@CuO Core-Shell Particle Nanoarchitectonics for Boosting Photocatalytic Oxidative Desulfurization.

Photocatalytic oxidation desulfurization (PODS) has emerged as a promising, ecofriendly alternative to traditional, energy-intensive fuel desulfurization methods. Nevertheless, its progress is still hindered due to the slow sulfide oxidation kinetics in the current catalytic systems. Herein, we present a MoO decorated on a CuO@CuO core-shell catalyst, which enables a new, efficient PODS pathway by generation of hydrogen peroxide (HO) with saturated moist air as the oxidant source.
