摘要：

Novel In2S3 nanosheets/graphene photocatalysts were fabricated by a cysteine-assisted one-pot hydrothermal method. Due to the intimate interfacial contact and efficient charge separation, superior visible-light activity for degrading organic dyes and reducing Cr(VI) were achieved. During the decoloring process of methyl orange, the average apparent rate for the as-synthesized composites with 1% graphene was almost 5 times higher than that of pure In2S3. This work provides new insights into utilizing In2S3/graphene composites as high-efficiency visible-light-driven photocatalysts for environmental remediation and energy conversion.
