采用半胱氨酸辅助的一锅水热法制备了新型In 2S 3纳米片/石墨烯光催化剂。由于紧密的界面接触和有效的电荷分离，实现了对有机染料的降解和对Cr（VI）的还原的上级可见光活性。在对甲基橙子的脱色过程中，添加1%石墨烯的复合材料的平均表观脱色率比纯In 2S 3的平均表观脱色率高近5倍。这项工作为利用In 2S 3/石墨烯复合材料作为高效可见光驱动的光催化剂用于环境修复和能源转换提供了新的见解。(C)2012爱思唯尔有限公司版权所有。
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.
