Abstract

Abstract: Efficient exfoliation and downsizing of Sb2 S3 and Bi2 S3 layered compounds by using scalable bipolar electrochemistry on their suspensions in aqueous media are here demonstrated. The resulting samples were characterized in detail by transmission electron microscopy, energy‐dispersive X‐ray spectroscopy, and X‐ray photoelectron spectroscopy; their electrochemistry toward hydrogen evolution was also investigated. Hydrogen evolution ability of exfoliated Sb2 S3 and Bi2 S3 was investigated and compared to the bulk counterparts.
