Leaf-like　monoclinic　BiVO4　and　yCo(x)Pd/BiVO4　(CoxPd　loading　(y)　=　0.060　-　0.092　wt%;　Co/Pd　molar　ratio　(x)　=　0.26　-　1.70)　photocatalysts　were　prepared　using　the　hydrothermal　and　polyvinyl　alcohol-protected　reduction　methods,　respectively.　The　Co-Pd　nanoparticles　(NPs)　with　a　size　of　4-6　nm　were　well　dispersed　on　the　surface　of　leaf-like　BiVO4.　The　bimetallic　Co-Pd-loaded　BiVO4　samples　performed　much　better　than　the　monometallic　Co-　or　Pd-loaded　counterpart,　with　the　0.062Co(1.70)Pd/BiVO4　sample　showing　the　best　photo-catalytic　performance　(the　time　for　90%　phenol　removal　was　3　h　under　visible　light　irradiation)　and　good　photocatalytic　stability.　The　pseudo-first-order　reaction　rate　constants　(0.4753　-　0.8367　h(-1)　obtained　over　yCo(x)Pd/BiVO4　were　much　higher　than　those　(0.0619　-　0.3788　h(-1))　obtained　over　BiVO4,　0.058Co/BiVO4,　and　0.083Pd/BiVO4,　with　the　0.062Co(1.70)Pd/BiVO4　sample　possessing　the　highest　rate　constant.　In-depth　investigations　of　X-ray　photoelectron　spectroscopy,　photoluminescence　spectroscopy,　and　photoelectrochemical　measurements　reveal　that　high　dispersion　of　bimetallic　Co-Pd　NPs　increased　the　surface　Pd-0　and　superoxide　anion　radical　concentrations　and　suppressed　the　recombination　of　photoinduced　electrons　and　holes　(hence　enhancing　the　photocatalytic　activity　of　yCo(x)Pd/BiVO4).　The　partial　deactivation　of　the　0.062Co(1.70)Pd/BiVO4　sample　after　15　h　of　three　recycle　tests　was　mainly　due　to　the　decrease　in　adsorbed　oxygen　species　concentration.　In　addition,　the　possible　photocatalytic　phenol　degradation　mechanism　over　the　0.062Co(1.70)Pd/BiVO4　sample　was　also　proposed.　We　believe　that　the　BiVO4-supported　Co-Pd　NPs　have　promising　applications　for　the　photocatalytic　elimination　of　organic　pollutants　in　wastewater.
