摘要 传统的二氧化钛(TiO2)存在一些问题,如能隙值过大只可响应紫外波段,光生电子与空穴极易在体内和表面复合。针对目前TiO2在光催化应用中存在的不足,提出了有效提升其光催化性能的实验方案。以高比率(001)面纳米TiO2粒子为研究对象,采用热裂解柠檬酸制备的石墨烯量子点(GQDs),在强碱水热条件下制备出GQDs修饰的海胆状TiO2。对所制样品的形貌与结构进行表征,并利用构建好的电化学平台,分析改性修饰对TiO2光催化性能的影响。结果表明,GQDs敏化的TiO2显示出优异的光催化性能。

Abstract: Conventional titanium dioxide(TiO2) has some problems,such as high energy gap value of which only responded to ultraviolet band,and recombination of photo-generated electrons and holes both inside and on the surface.According to the research shortcoming in photocatalytic application of TiO2,a series of experimental protocols to improve the photocatalytic efficiency were mainly focused.The truncated octahedral TiO2 with high ratio (001) active facet was the study object.TiO2 stripped in alkali environment was modified by graphene quantum dots (GQDs) prepared in optimum process.The GQDs was fabricated by citric acid pyrolysis method.Then,the morphology and structure were characterized.The photocatalytic activities were characterized through electrochemical test platform to analyze the effect of GQDs in promoting the photocatalytic activity of traditional anatase TiO2.The results showed that TiO2 sensitized by GQDs performed excellent photocatalytic activity.
