摘要

本研究以氧化石墨烯(GO)/CuBi2O4/TiO2为催化剂，在紫外光照射下对亚甲基蓝（MB）进行光催化降解研究。降解动力学作为系统中氧化石墨烯负载的函数进行监测。结果表明，氧化石墨烯的最佳负载为0.5 wt%，而较高的氧化石墨烯负载会降低亚甲基蓝（MB）的光催化降解。结果还表明，样品表面改性的增加提高了降解动力学。本研究表明，通过适当的GO负载和异质结的形成，GO/CuBi2O4/TiO2可以作为有效的紫外光催化剂。

Characteristics and Heterostructure of Graphene Oxide (GO)/CuBi2O4/TiO2 Composites

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.
