Abstract:Tuning the electrocatalytic properties of MoS 2 layers can be achieved through different paths, such as reducing their thickness, creating edges in the MoS 2 flakes, and introducing S-vacancies. We combine these three approaches by growing MoS 2 electrodes by using a special salt-assisted chemical vapor deposition (CVD) method. This procedure allows the growth of ultrathin MoS 2 nanocrystals (1−3 layers thick and a few nanometers wide), as evidenced by atomic force microscopy and scanning tunneling microscopy.… Show more
Electrocatalytic water splitting with earth-abundant materials is still a critical challenge to obtain high activity and durability simultaneously, due to the complexity of designing electrocatalysts from physical chemistry, material science...
Quantitative elemental analysis of van der Waals materials can be done by XPS by using high-throughput mechanical exfoliations, which favour the coverage of large area substrates with flakes using minimal quantities of starting materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
