Hybrid carbon dot/Ni3S2 architecture supported on nickel foam for effective light collection and conversion

摘要

We offer a powerful strategy that makes use of in-situ Ni3S2 formation on porous wall of Ni foam to enhance light capture and energy conversion of carbon dots (CDs). The obtained hybrid of CDs and Ni3S2 is well characterized and shows broad and strong light absorption and excellent photooxidation activities. In this hybrid, both CDs and Ni3S2 play different roles in energy conversion process and their combined architectures determine efficiency of light harvesting. Not only could our presented product be particularly promising for oxidation and degradation of organic species, but also show more competitive advantage in separation and recovery from the reaction system than the powder as a photocatalyst.
