Abstract：

A　dual-solvent　strategy　is　developed　to　enable　uniform　deposition　of　transition　metal　sulfide　(Ni3S4　or　CoS2)　nanoparticles　onto　the　surface　of　the　porphyrinic　metal-organic　framework　(MOF)　PCN-222(Zn).　This　approach　allows　the　construction　of　heterojunction　composites　with　a　well-defined　interface　and　efficient　charge　separation,　and　the　resulting　PCN-222(Zn)-Ni3S4　composites　demonstrate　enhanced　photocatalytic　hydrogen　evolution　activity　under　UV–vis　light　with　a　47-fold　enhancement　over　pristine　PCN-222(Zn)　or　a　16-fold　enhancement　over　nickel　sulfide　alone.　The　heterojunction　design　further　stabilizes　the　photocatalyst　during　prolonged　irradiation　and　enables　consistent　recyclability　without　significant　activity　loss.　This　work　highlights　the　potential　of　heterojunction　engineering　with　MOF　and　transition　metal　sulfide　for　the　development　of　efficient,　stable,　and　earth-abundant　photocatalysts　for　sustainable　hydrogen　production.　©　2025　Wiley-VCH　GmbH.
