Converting　solar　energy　directly　into　chemical　energy　by　means　of　artificial　photosynthesis　provides　a　flexible　option　for　energy　storage　and　transportation.　The　material＇s　structure　and　morphology,　wisely　tailored　via　a　nanochemistry　approach,　could　lead　to　desirable　photocatalytic　performances.　The　smallest　dimension　structures,　one-dimensional　nanostructures　which　could　be　utilized　for　efficient　electrons　and　optical　excitations　transmit,　are　expected　to　play　an　important　role　in　photocatalytic　organic　synthesis,　a　typical　example　of　artificial　photosynthesis.　In　this　review,　we　describe　current　progresses　in　photocatalytic　organic　synthesis　research,　including　photocatalytic　selective　oxidation　of　alcohols,　nitroaromatic　compounds　reductions,　and　reduction　of　CO2　to　renewable　fuels,　with　centered　on　profits　of　one-dimensional　morphology.　The　possible　research　directions　are　presented　along　with　typical　instances　of　some　current　advances　in　this　area,　which　involves　co-catalysts,　light-absorbers　as　well　as　charge　transport　units　of　one-dimensional　nano-structures.
