Abstract

As a set of photocatalyst and its co-catalyst with exceptional photo-degradation performance, rGO exhibits a conspicuous board-spectrum sensitization effect to TiO₂. It has been widely recognized by studies in the field of water treatment that, their synergistic can also markedly complement short carrier lifetime and other shortcomings of TiO₂. Over the years, research conducted on TiO₂-rGO binary composite material manifests its wide modifiable space for seeking a better degradation performance and a higher solar availability. We presents an overview study on the latest modification methods of the TiO₂-rGO binary composite material and divide them into categories. This article focuses on the four of them as follows: morphology and crystalline engineering, doping modification, semiconductor ternary combination, noble-metal decoration. Furthermore, the in-depth degradation mechanism and novel structure design of the modified TiO₂-rGO binary composite materials are reviewed. Ongoing difficulties and promising opportunities have been summarized and expected in this article, aiming to guide the design and study of the future photo-degradation nanomaterial.

期刊介绍： Early dissemination of important findings from Asia which may lead to new concepts in catalyst design is the main aim of this journal. Rapid, invited, short reviews and perspectives from academia and industry will constitute the major part of Catalysis Surveys from Asia . Surveys of recent progress and activities in catalytic science and technology and related areas in Asia will be covered regularly as well. We would appreciate critical comments from colleagues throughout the world about articles in Catalysis Surveys from Asia . If requested and thought appropriate, the comments will be included in the journal. We will be very happy if this journal stimulates global communication between scientists and engineers in the world of catalysis.
