State-of-the-art progress in overall water splitting of carbon nitride based photocatalysts
Converting solar energy into hydrogen (H2) by photocatalytic water splitting is a promising approach to simultaneously address the increasing energy demand and environmental issues. Half decade has passed since the discovery of photo-induced water splitting phenomenon on TiO2 photoanode, while the solar to H2 efficiency is still around 1%, far below the least industrial requirement. Therefore, developing efficient photocatalyst with a high energy conversion efficiency is still one of the main tasks to be overcome. Graphitic carbon nitride (g-C3N4) is just such an emerging and potential semiconductor. Therefore, in this review, the state-of-the-art advances in g-C3N4 based photocatalysts for overall water splitting were summarized in three sections according to the strategies used, and future challenges and new directions were discussed.
