By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Hydrogen. According to news originating from Tianjin, People's Republic of China, by VerticalNews correspondents, research stated, "The inversely structured TiO2 nanotubes-array (TiO2-NA) and CdS-modified TiO2 nanotubes-array (CdS/TiO2-NA) with graphene quantum dots (GQDs) anchored inside were prepared through a facile impregnation method. The catalysts were characterized by multiple techniques of SEM, TEM, XRD, Raman spectroscopy, XPS, TG and diffuse reflectance UV/Vis absorption spectroscopy."
Our news journalists obtained a quote from the research from Tianjin University, "The results of TEM, XPS and Raman spectroscopy indicate that the GQDs were really formed and successfully anchored into the TiO2-NA and CdS/TiO2-NA. The activity evaluation results show that the hydrogen evolution rate during photocatalytic water splitting was greatly improved after loading GQDs into TiO2-NA and CdS/TiO2-NA. By breaking graphene into GQDs, the light-filtering effect of graphene was remarkably inhibited as compared with that of conventional large graphene sheets. Moreover, the overall morphology of TiO2 nanotube array could be well maintained after anchoring GQDs inside, which is favorable to mass transfer."
According to the news editors, the research concluded: "The catalyst design strategy proposed in present work can be extended to other photocatalytic systems."
