Abstract
In this study, the photocatalytic degradation of methylene blue (MB) was investigated using graphene oxide (GO)/CuBi2O4/TiO2 catalysts under UV irradiation. The degradation kinetics were monitored as a function of GO loading in the system. It was observed that the optimal GO loading was 0.5 wt%, while higher GO loadings reduced the photocatalytic degradation of methylene blue (MB). The results also showed that increased surface modification of the sample enhanced the degradation kinetics. This study demonstrated that, with an appropriate GO loading and the formation of a heterojunction, GO/CuBi2O4/TiO2 can serve as an effective UV photocatalyst.
期刊介绍：
Topics in Catalysis publishes topical collections in all fields of catalysis which are composed only of invited articles from leading authors. The journal documents today’s emerging and critical trends in all branches of catalysis. Each themed issue is organized by renowned Guest Editors in collaboration with the Editors-in-Chief. Proposals for new topics are welcome and should be submitted directly to the Editors-in-Chief.
The publication of individual uninvited original research articles can be sent to our sister journal Catalysis Letters. This journal aims for rapid publication of high-impact original research articles in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
