Progress　in　photochemistry　and　concomitant　significant　advances　in　flow　chemistry,　nanochemistry,　and　solid　state　lighting　from　the　past　decade　hold　the　potential　to　make　visible-light　photocatalysis　part　of　the　synthetic　tools　used　by　the　fine　chemical　and　pharmaceutical　industries　for　the　production　of　active　ingredients.　This　study　identifies　key　advances　and　remaining　gaps　toward　the　widespread　adoption　of　heterogeneously　catalyzed　processes　using　visible　photons　for　manufacturing　functional　molecules　on　a　large　scale..
