Photocatalytic　hydrogen　(H2)　production　and　selective　organic　synthesis　provide　an　environmentally　friendly　strategy　to　generate　solar　fuel　and　high-value　organic　products,　respectively.　However,　these　reactions　usually　either　suffer　from　low　reaction　kinetics　or　need　the　aid　of　sacrificial　reagents　as　electron　donors　or　acceptors,　thus　lacking　in　economic　benefit.　Is　there　any　synergetic　effect　between　these　two　types　of　reactions?　Recently,　combining　H2　evolution　with　selective　organic　synthesis　in　one　photocatalytic　system　has　been　reported.　In　these　dual-functional　photocatalytic　reactions,　both　photoexcited　electrons　and　holes　can　be　utilized　to　produce　target　products,　making　the　overall　process　more　efficient.　In　this　minireview,　we　begin　with　a　concise　discussion　of　the　fundamental　principles　of　simultaneous　photocatalytic　H2　production　and　organic　synthesis　using　semiconductor-based　photocatalysts.　Emphasis　is　placed　on　emerging　materials　or　novel　strategies　selected　in　this　dual-functional　photo-redox　reaction　system,　including　the　characteristics　of　photocatalysts　and/or　potential　reaction　mechanisms.　Finally,　remaining　challenges　and　personal　perspectives　on　future　development　in　this　field　are　put　forward.　It　is　expected　that　this　review　will　provide　inspirational　guidance　on　the　rational　design　of　photocatalysts　with　dual-functional　reaction　capability,　invigorating　the　development　of　economical　and　efficient　H2　generation　and/or　value-added　organic　synthesis.　©　2023　The　Authors
