Graphene‐Based Materials for Hydrogen Generation from Light‐Driven Water Splitting

Abstract

Hydrogen production from solar water splitting has been considered as an ultimate solution to the energy and environmental issues. Over the past few years, graphene has made great contribution to improving the light-driven hydrogen generation performance. This article provides a comprehensive overview of the recent research progress on graphene-based materials for hydrogen evolution from light-driven water splitting. It begins with a brief introduction of the current status and basic principles of hydrogen generation from solar water splitting, and tailoring properties of graphene for application in this area. Then, the roles of graphene in hydrogen generation reaction, including an electron acceptor and transporter, a cocatalyst, a photocatalyst, and a photosensitizer, are elaborated respectively. After that, the comparison between graphene and other carbon materials in solar water splitting is made. Last, this review is concluded with remarks on some challenges and perspectives in this emerging field.

Graphene-based transition metal oxide nanocomposites for the oxygen reduction reaction

“…Graphene-based materials also outperform graphene in various fields, such as in electronic or photo detectors, 27,28 capacitors, 29,30 transparent electrodes, 28 sensors, 31 electrocatalysis, 32,33 environmental remediation, [34][35][36] and energy applications. 37 The successful achievements of graphene-based devices benefit from their ideal single-atom thick substrates for the growth of functional nanomaterials.…”

Robust graphene-based monoliths of homogeneous ultramicroporosity

“…The obtained highly electrical conductive properties are very important for an application of these monoliths for energy storage [21] or as catalysts for oxygen reduction [22] or water splitting processes where the fast electron transfer is a desired feature [23]. Interestingly, the resistance values measured are comparable through both dimensions, especially for the monoliths heated at 1123K indicating the presence of conductive paths in various directions of the monoliths' volumes.…”
