摘要

In this study, we present a new fluorescence imaging-based high-throughput screening method to evaluate the catalytic performance of the polymetallic sulfide complex g-C3N4. In order to obtain a large number of catalysts, we chose the sulfates of three metals (Cd, Cu, and Ni) to modify g-C3N4. A catalyst library consisting of polymetallic sulfide composite carbon nitride materials (M3S/g-C3N4, M = CdxCuyNi1-x-y) was obtained using a color ink-jet printing technique. The degradation reaction of eosin solution was carried out under 365 nm UV light. According to the intensity of fluorescence change, the high-efficiency catalysts are the following three combinations: Cd0.37Cu0.53Ni0.10 S/g-C3N4, Cd0.11Cu0.41Ni0.48S/g-C3N4 and Cd0.31Cu0.39Ni0.30S/g-C3N4.
