Low　cost　and　easily　made　bismuth　tungstate　(Bi2WO6)　could　be　one　of　the　key　technologies　to　make　chemicals　and　fuels　from　biomass,　atmospheric　carbon　dioxide　and　water　at　low　cost　using　solar　radiation　as　an　energy　source.　Its　narrow　band　gap　(2.8　eV)　enables　ideal　visible　light　(λ　>　400　nm)　absorption.　Yet,　it　is　the　material＇s　shape,　namely　the　superstructure　morphology　wisely　created　via　a　nanochemistry　approach,　which　leads　to　better　electron-hole　separation　and　much　higher　photoactivity.　Recent　results　coupled　to　the　versatile　photochemistry　of　this　readily　available　semiconductor　suggest　that　the　practical　application　of　nanochemistry-derived　Bi2WO6　nanostructures　for　the　synthesis　of　value-added　fine　chemicals　and　fuel　production　is　possible.　We　describe　progress　in　this　important　field　of　chemical　research　from　a　nanochemistry　viewpoint,　and　identify　opportunities　for　further　progress.　This　journal　is　©　the　Partner　Organisations　2014.
