Findings from Peking University Reveals New Findings on Photocatalytics

June 13, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Photocatalytics. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "A simple and efficient route for the controllable synthesis of dumbbell-shaped BiVO4 hierarchical structures at a large scale with uniform size and shape distributions was demonstrated, where the as-synthesized BiVO4 products were then incorporated with prepared reduced graphene oxide (RGO) sheets to form dumbbell-shaped BiVO4/RGO composites."

Our news journalists obtained a quote from the research from Peking University, "The obtained composites were well characterized with the aid of various techniques to study their morphological, physical, optical, and photo-chemical properties. Photocatalytic capacities of the pure BiVO4 dumbbells and BiVO4/RGO composites have been evaluated by investigating the degradation of Rhodamine B (RhB)-contained wastewater under natural sunlight irradiation, where a noticeable augmentation in the natural-sunlight-driven decolorization efficiency (approx. 26% increase compared with that of pure BiVO4) of RhB could be achieved on the prepared BiVO4/RGO composites under experimentally optimum conditions."

According to the news editors, the research concluded: "The cycle-stabilized photocatalytic performances of the BiVO4/RGO composites have also been probed."
