Tetrapod-shaped　Ag3PO4　microcrystals　with　an　increased　percentage　of　exposed　{110}　facets　have　been　successfully　prepared　for　the　first　time,　and　a　possible　growth　mechanism　is　proposed.　The　as-prepared　Ag3PO4　tetrapods　exhibit　excellent　photocatalytic　activities　under　visible　light　illumination,　which　may　be　ascribed　to　the　relatively　higher　reactivity　of　{110}　facets.
