A　straightforward　hydrothermal　method　was　employed　to　fabricate　WO3/MoO(3　)composites,　with　the　addition　of　ascorbic　acid　(Vc)　for　modification,　resulting　in　WO3/MoO(3　)composites　with　oxygen　defects　(WO3/MoO3-x).　WO3/MoO(3-x　)exhibits　exceptional　adsorption-photocatalytic　properties,　demonstrating　strong　adsorption　capability　for　dyes　achieved　through　hydrogen　bonding　and　electrostatic　interactions.　For　all　products,　adsorption　rates　for　methylene　blue　(MB)　exceeded　95　%　when　reaching　adsorption　equilibrium.　Moreover,　an　increase　in　molybdenum　(Mo)　content　endows　the　samples　with　enhanced　adsorption　capacity　for　methyl　orange　(MO)　and　improved　photocatalytic　performance.　Dynamic　fitting　of　the　samples　revealed　that　when　the　W/Mo　molar　ratios　is　2:8,　the　product　W2Mo8-Vc,　exhibits　the　highest　photocatalytic　activity.　After　3　h　of　illumination,　W2Mo8-Vc　achieves　a　remarkable　photocatalytic　efficiency　of　98　%　for　dyes.　This　research　not　only　successfully　recycles　W-Mo　alloy　scrap　but　also　yields　WO3/MoO(3-x　)composites　with　adsorption-photocatalytic　properties,　offering　a　novel　approach　for　the　recycling　of　W-Mo　secondary　resource.
