Abstract
Single-atom Pt immobilized in the lattice of CoP mesoporous nanosheets (MNSs) grown on carbon fiber cloth (CFC) (Pt<sub>at</sub>–CoP MNSs/CFC) was synthesized for the HER in alkaline solution and seawater. The improved HER is mainly attributed to water dissociation that becomes spontaneous on Pt<sub>at</sub>–CoP MNSs/CFC.
