splitting (2H 2 O → 2H 2 + O 2 ), consisting of hydrogen evolution and oxygen evolution reaction (HER/OER), can convert electricity to chemical energy in H 2 and O 2 for further energy applications. The practical application of overall water splitting, however, is still limited due to the lack of effective and stable catalysts to reduce reaction energy barrier and enhance Faraday efficient for both reactions. [6][7][8][9][10] Different materials have been studied for overall water splitting catalysis, like metal chalcogenides, metal carbides, oxides, etc. The transition metal carbides, especially graphene, have a better electroconductivity, ductility, and high surface area which display excellent performance in water splitting. [11][12][13] Oxides as another abundant species on the earth also show better water splitting performance, but their stability in hard media is not very good. [14][15][16] The layered double hydroxides (LDH) with unique structure, abundant interstratified electrons and channels for intermediate adsorption and desorption display wonderful water splitting performance. [17][18][19][20] Additionally, the metalorganic frameworks (MOFs) and their based nanocrystals as newly nanomaterials have got much attention in various fields, but their structure limited the active sites exposure for the complete coordinative metal sites. [21][22][23][24][25] Therefore, it is important to enable the cost-effective, large-scale production of these catalysts, and further improve the performance and efficiency of overall water splitting.Transition metal chalcogenides have many different compositions with various lattice structure, while those materials also have unique electronic structures.

Hollow Structured Metal Sulfides for Photocatalytic Hydrogen Generation

et al. 2020

View full text Add to dashboard Cite

Metal sulfides (MSs) are a promising class of materials for photocatalytic hydrogen generation due to their distinct features of photosensitivity, electrical conductance, and photoelectrochemical stability. However, the photocatalytic activity of solid structured MSs is often compromised due to low incident photon absorption, high charge carrier recombination, inadequate catalytic active sites, and slow mass and charge diffusion. The development of hollow structured MSs alleviates these limitations and achieves higher H2 generation than solid structured counterparts. This minireview aims to review the recent advances in the development of synthetic methods for various hollow structured MSs that are designed to enhance light absorption and fasten mass diffusion. Particularly, this report highlights the advent of sophisticated heterostructured hollow MSs for the application in photocatalysis, in which the formation of heterojunction at the semiconductor interface ensures spatial separation of charge carriers. The synergy between the hollow structure and heterostructure dramatically increases the H2 generation rate by providing increased light absorption, delayed charge recombination, and accelerated mass diffusion. We also point to potentially fruitful research directions in this field, in hope that this minireview serves as a stepping stone for the future development in hollow MSs for photocatalytic applications and beyond.
