Photo-driven chemical transformation, also known as photocatalysis, has emerged as a sustainable technology in solving various issues from environmental pollution to energy security. It is straightforward that the success of a photocatalytic process is highly dependent on the type of photocatalyst system being utilized. Graphene, the wonder material, in particular, has emerged as compelling semiconductor support because of its superlative properties such as large specific area, excellent electronic conductivity, high transparency, and good flexibility. Despite the affluent number of studies on graphene-based photocatalysts, there is a paucity of reviews discussing the relationship between the graphite exfoliation routes and the associated properties of graphene nanomaterials which can impart a non-negligible influence on photocatalytic performance. Here, the impact of graphite exfoliation mutes on the resultant graphene properties as photocatalyst support is reviewed. The most common top-down graphite exfoliation methods are reviewed, including chemical, liquid-phase, mechanical, and electrochemical exfoliations. The advantages and weaknesses of each exfoliation approach are systematically reviewed while considering the concomitant structural properties and photocatalytic characteristics of the produced graphene. A comparative assessment of different graphene exfoliation mutes and their implications on photocatalytic performance is revealed. Recent progress on the applications of exfoliated graphene for various photocatalytic processes, including environmental remediation, water splitting, and CO2 photoreduction to solar fuels, are discussed in-depth.
