A flexible CdS nanorods-carbon nanotubes/stainless steel mesh photoanode for boosted photoelectrocatalytic hydrogen evolution

An innovative flexible reticular photoanode (CdS-nanorods/CNTs coated on stainless iron mesh) was designed for efficiently driving photoelectrocatalytic (PEC) hydrogen (H-2) evolution under visible-light irradiation. Such CdS-NRs/CNTs-based flexible photoanodes exhibited a record-breaking H-2 evolution rate (728 mmol h(-1) g(-1)) among the reported CdS-based photoanodes under visible-light irradiation owing to the photoelectron transport channels (CNTs) and high separation efficiency of electrons and holes.
