Abstract

A novel graphene supported Mn-doped Eosin Y based nanocomposite has been successfully prepared by hydrothermal method. Eosin Y–graphene nanocomposite acts uniquely as a metal free visible light photocatlyst without TiO2 or Bismuth Vanadate and incorporation of Mn further enhances the activity of the composite. Photocatalyst was active under visible light and photocatalytic activity strongly depends on pH of the degrading dye solutions. Photo-activation of the system in visible light is the consequence of Eosin Y doping while strong photocatalytic performance of the composite is attributed to reduce graphene oxide that supports better mobility of electrons within composites as well as provide more sites for photo-reduction. This newly developed composite has a potential to remove industrial dyes efficiently and cheaply to reduce water pollution.

锰结合曙红Y染料/石墨烯纳米复合材料:高效可见光活性光催化剂

摘要

通过水热法成功制备了新型石墨烯负载的Mn掺杂曙红Y基纳米复合材料。曙红Y-石墨烯纳米复合材料独特地充当无TiO 2的无金属可见光光催化剂钒酸铋或钒酸铋,掺入锰可进一步增强复合材料的活性。光催化剂在可见光下具有活性,光催化活性强烈取决于降解染料溶液的pH。该体系在可见光中的光活化是曙红Y掺杂的结果,而复合材料的强大光催化性能归因于氧化石墨烯的还原,氧化石墨烯支持复合材料中电子的更好迁移性并提供更多的光还原位。这种新开发的复合材料具有高效,廉价地去除工业染料以减少水污染的潜力。
