Monoclinic　BiVO4　material　was　successfully　synthesized　through　a　hydrothermal　method,　and　silver　(Ag)　nanoparticles　were　deposited　onto　the　surface　of　BiVO4　using　the　photo　deposition　technique.　The　gas-sensing　outcomes　demonstrate　that　the　BiVO4　material　loaded　with　2　wt%　Ag　has　a　good　gas-sensing　response　to　isopropanol,　which　is　about　three　times　that　of　pure　BiVO4.　In　addition,　it　exhibits　a　fast　response　within　10　s　and　well-stability.　The　improved　gas　sensing　properties　primarily　come　from　the　catalytic　and　spillover　effect　mechanism　of　Ag.
