Abstract

    Photocatalysis is considered to be a green and promising technology for transforming organic contaminants into nontoxic products. In this work, the CuO/tourmaline composite with zero-dimensional/two-dimensional (0D/2D) CuO architecture was obtained via a facile hydrothermal process. CuO chemically interacted with tourmaline via Si-O-Cu bond. The specific surface area of the CuO/tourmaline composite (23.60 m2 g-1) was larger than that of pristine CuO (3.41 m2 g-1). Three predominant reactive species of superoxide radical (O2•-), hydroxyl radical (•OH), and h+ were generated by the CuO/tourmaline composite aqueous suspension system under light irradiation. The CuO/tourmaline composite exhibited excellent photocatalytic capacity for the decomposition of organic pollutants, which was ascribed to the increase in the quantity of adsorption-photoreactive sites and the efficient utilization of photoinduced charge carriers benefited from tourmaline. This study offered a facile strategy for the construction of 0D/2D CuO structure and the design of tourmaline-based functional composite photocatalysts for the treatment of organic contaminants in waster.
