Designing a Z-scheme system based on photocatalyst panels towards separated hydrogen and oxygen production from overall water splitting
Photocatalytic water splitting on particulate semiconductors is a promising approach for large-scale hydrogen production. However, the mixing of H 2 and O 2 whether through traditional one-step or two-step photocatalytic overall water splitting requires additional steps for their separation, which l...
