Oxides free nanomaterials for (photo)electrochemical water splitting

초록

The continuously increasing energy demand due to population growth has caused rapid consumption of fossil fuels and severe environmental issues. Hence, sustainable energy production via photoelectrochemical water splitting (PECWS) technique by using nanostructured materials has become an important approach to solve the energy demands. Especially, the oxide-free nanostructured materials like metal nitrides (MNs), metal phosphides (MPs), and metal sulfides (MSs) have become promising candidates for the PEC water splitting applications. Therefore, in this book chapter, we have discussed the important properties of oxide-free materials for efficient PEC hydrogen generation. We have highlighted the synthesis mechanisms of binary and ternary metal nitrides, phosphides, and sulfides of various structures and recent advances of these fascinating nanomaterials for PEC hydrogen generation and important properties and mechanisms helpful for improved activities. Finally, we discussed the important challenges and future prospects in this field for efficient solar hydrogen generation. © 2022 Elsevier Inc. All rights reserved.
