1. Introduction
At present, frontier scientific and technological research into the fields of energy and environmental protection are becoming increasingly challenging due to the need for key materials with high efficiency and functionality. Ignited by immense technological potential, the research on advanced carbon nanomaterials, particularly graphene has experienced an extensive growth over the past decade [1–4]. Fig. 1 depicts the exponential increase in the number of publications based on graphene and its derivatives from 2004 to 2014. As a simple hexagonal lattice of carbon atoms, graphene provides a highly electronic and thermally conductive surface, which is also the thinnest known material and the strongest ever reported [5]. One specific branch of graphene research is focused on chemically derived graphene oxide (GO) [6,7]. As a newly emerging two dimensional (2D) material, GO possesses many intriguing properties, including mechanical, electronic, optical, electrochemical and chemical reactivity [8]. GO sheets are composed of two primary regions: (1) the hydrophobic -conjugated sp2 domains and (2) the sp3 domains with hydrophilic oxygen-containing functionalgroups. The widely accepted structure of GO depicts carboxylic acid at the edges, and hydroxyl and epoxide groups residing at the basal plane [6]. Despite the distortion of the intrinsic conjugated system, these complex cocktails of functionalities can provide potential advantages for employing GO in numerous applications. The polar oxygen-containing groups on GO render it strongly hydrophilic, allowing it to be dispersed in a number of solvents, particularly in water [9]. Furthermore, the physicochemical properties of GO can be tuned by engineering its atomic and chemical structures [10]. From a broader perspective, the fascinating properties and tunability inherent to GO sheets are very promising for facilitating a wide range of applications, including but notlimited to electronics (conductive films and sensors) [11], composite materials [12], clean energy devices [13] and biology [14]. Several reviews on these topics have been reported in literature [15–20]. However, to the extent of our knowledge,no review articles onthe application of GO in the field of photocatalysis have been published. Photocatalysis has become one of the most studied fields due to the increasingly cogent call for environmental remediation [21]. The direct conversion of solar energy into chemical energy through this system provides an opportunity to simultaneously address both the environmental and energy issues faced today. While many different photocatalytic materials such as semiconductors, transition-metal complexes etc. have been developed [22], the possibility of employing pure GO nanosheets for efficient
