Abstract

In this article, we proposed a glycine-assisted double-solvent thermal approach to controllably synthesize a series of Cu2O microcrystals. In a waterethanol system, the products have predominantly octahedral and polyhedral structures; while in waterglycol system or a waterglycerin system, the products have more tendencies to form a cubic type structure. Compared with the conventional route, this method provides a mild technique for various morphologies of Cu2O and omits the need for template or surfactant in such mild conditions. The effects of glycine and double solvents on the morphology control have also been discussed. The investigations of the application of these crystals for photodegradation of rhodamine B and mechano-catalytic overall water splitting to produce H2 reveals that all these products have great catalytic activities and the catalytic activities are affected by the morphology of the Cu2O crystals.
