A　ternary　photocatalyst　has　been　successfully　constructed　through　the　integration　of　Au,　CdS　and　hollow　carbon　nitride　nanospheres　(HCNS),　where　Au　nanoparticles　were　designed　to　shuttle　interparticle　transfer　of　charge　carriers　between　CdS　and　HCNS　photosensitizers　to　establish　two-photon　(Z-scheme)　photocatalytic　tandem　systems　for　solar　fuel　production.　The　solid-state　CdS-Au-HCNS　Z-scheme　nanocomposites　were　efficient　for　H2　evolution　(with　a　quantum　yield　of　8.7%　at　420　nm)　and　CO2　reduction　catalysis　with　visible　light　irradiation.　This　work　further　proves　the　feasibility　of　employing　hollow　conjugated　polymer　photocatalysts　in　the　function-led　design　of　artificial　Z-type　photosynthetic　machinery　on　soft　material　interfaces.　©　2015　The　Royal　Society　of　Chemistry.
