Abstract
The presence of contaminants, such as synthetic dyes and herbicides, in water has led to serious environmental and human health problems worldwide. Therefore, the effective removal of pollutants from aquatic environments has attracted considerable attention. The combination of metal-organic frameworks and advanced carbon materials has attracted great attention in many application fields because the hybrid material has many positive properties from both components. In this paper, NCDs/FeNH2BDC composite was fabricated through in situ synthesis, in which N-containing carbon dots (NCDs) were mixed with MOF precursor solution in different ratios before undergoing the cooling step. It has been demonstrated that introducing a certain amount of N-containing carbon dots affects the characteristic features and improves the photocatalytic performance of the final product. The optimal doping content of N-containing carbon dots in the NCD/FeNH2BDC composite was determined to be 400 mg. SEM images show that S400 appears as hexagonal micro-axial crystals with an average size of 500 nm. In addition, the S400 catalyst also exhibits excellent photocatalytic activity for the degradation of Rhodamine B at a pH range of 3 to 5. Under optimal conditions, Rhodamine B is achieved within 60 min and the yield Removal reached nearly 100% after 5 cycles. Finally, the efficiency of S400 in treating the active ingredient pretilachlor in pesticides in water is up to 93.08%.
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.
