Progress in Photocatalytic Degradation of Organic Wastewater by Graphene Binary Composites

Abstract

Graphene composites not only have most advantages of graphene, but also have the characteristics of easy regulation, morphology and so on. Among many applications, graphene composite photocatalytic degradation of organic wastewater is one of the most likely graphene technologies. At present, the most studied graphene complexes include graphene monophyletic complex, graphene binary complex and graphene ternary complex. In this paper, the preparation of graphene binary complex and the research status of photocatalytic degradation of organic wastewater are summarized, and the existing problems are analyzed in order to provide a reference for the further research and application of graphene complex photocatalytic degradation of organic wastewater.

Advanced graphene-based (photo & electro) catalysts for sustainable & clean energy technologies

“…Yet, these methods have limitations in capturing the complete chemical and electronic structure of single-layer GO. To address this, the authors employed conductive atomic force microscopy (C-AFM) to simultaneously visualize the mechanical and electrical properties of single-layer GO, revealing distinct domain structures determined by the prevalence of sp 2 -or sp 3 -carbon regions. The study emphasizes the heterogeneous conductivity of singlelayer GO at the nanoscale, highlighting the significance of the chemical composition, particularly oxygen density, in determining its properties.…”

“…The study emphasizes the heterogeneous conductivity of singlelayer GO at the nanoscale, highlighting the significance of the chemical composition, particularly oxygen density, in determining its properties. Additionally, the local current-voltage (I-V) characteristics in the vertical direction of the GO sheet showcase differing conductance values for regions rich in sp 2 and sp 3 carbon. The utilization of friction, conductance mapping, and scanning transmission X-ray microscopy (STXM) further confirmed the presence of GO domains with varying sp 2 to sp 3 ratios at a submicron scale.…”

“…In order to address issues like the production of clean energy, water purification, the reduction of air pollution, and the synthesis of chemicals with added value, both sectors have demonstrated great promise. [1][2][3][4][5][6] In order to provide a thorough and organised overview of recent developments and successes in the photocatalytic and electrocatalytic applications of graphene-based materials, this review paper seeks to present a comprehensive and systematic analysis of those fields. The review will go over the many applications and features that have been investigated in this quickly developing subject.…”
