Abstract
- In this work, we develop a novel environmentally friendlystrategy toward one-pot synthesis of CuS nanoparticle-decorated reducedgraphene oxide (CuS/rGO) nanocomposites with the use of l-cysteine, an amino acid, as a reducing agent, sulfur donor, andlinker to anchor CuS nanoparticles onto the surface of rGO sheets.Upon visible light illumination (λ > 400 nm), the CuS/rGOnanocomposites show pronounced enhanced photocurrent response andimproved photocatalytic activity in the degradation of methylene blue(MB) compared to pure CuS. This could be attributed to the efficientcharge transport of rGO sheets and hence reduced recombination rateof excited carriers. [ABSTRACT FROM AUTHOR]
