Indium　vanadate　(InVO4)　is　an　up-and-coming　semiconductor　photocatalyst　for　energy/environment-related　applications,　and　has　attracted　tremendous　attention　in　the　last　few　decades,　owing　to　its　suitable　band　gap,　high　thermal　and　chemical　stability,　and　outstanding　photocatalytic　performance.　However,　the　low　solar-energy　utilization　efficiency　of　InVO4　material　constrains　its　further　development,　mainly　due　to　the　sluggish　separation　and　migration　kinetics　of　charge　carriers.　Fortunately,　recent　breakthroughs　have　been　achieved　in　both　enhancing　the　efficiency　and　clarifying　the　underlying　mechanism　for　photocatalytic　applications.　Therefore,　it　is　necessary　and　urgent　to　summarize　these　research　efforts　and　breakthroughs　upon　InVO4-based　nanomaterials　to　improve　the　photocatalytic　efficiency　and　speed　up　the　commercialization.　In　this　review,　we　systematically　summarize　the　recent　experimental　and　computational　developments　of　the　modifications　of　InVO4-based　photocatalysts　by　morphology　control,　element　doping,　and　hetero-junction　construction.　Then,　we　give　an　overview　of　their　promising　photocatalytic　applications.　Finally,　the　perspectives　on　the　challenges　faced　and　potential　future　research　directions　on　InVO4-based　photocatalysts　is　given.　We　aim　to　provide　guideline　for　the　rational　design　and　fabrication　of　high　efficient　InVO4-based　photocatalysts　for　energy　and　environmental　applications.
