Metal　oxides　based　on　Cu-Sr,　Sr-Cd　and　Cd-Cu　were　synthesized　by　mild　and　cost　effective　co-precipitation　method.　XRD　and　SEM　were　utilized　in　order　to　investigate　the　phase　structure,　composition　and　morphology　of　as　synthesized　metal　oxides.　Crystallite　size　calculated　through　XRD　was　found　to　be　40.36,　49.97　and　82.62　nm　for　Cu-Sr,　Sr-Cd　and　Cd-Cu　metal　oxides　whereas,　SEM　indicated　particle　size　ranged　from　(44-88)nm.　Elemental　contents,　functional　groups　and　thermal　stability　of　these　metal　oxides　were　determined　via　XPS,　FTIR　and　TGA.　Band　gap　energies　were　measured　as　1.57,　1.64　and　1.61　eV　while,　BET　analysis　indicated　surface　area　similar　to　9.86,　1.99　and　49.78m(2)/g　with　total　pore　volume/average　aperture　size　similar　to　0.0348　ml/g/1.0934　nm,　0.0127　ml/g/0.1101　nm　and　0.1080　ml/g/0.9254　nm　for　Cu-Sr,　Sr-Cd,　and　Cd-Cu　metal　oxides　respectively.　These　metal　oxides　were　used　as　photocatalysts　for　the　degradation　of　MB　and　MO　dyes　under　solar　light　irradiation　showing　higher　catalytic　activity　with　86,　78　and　67　%　degradation　for　MB　dye,　while　80,　50　and　69　%　degradation　was　observed　for　MO　dye　within　total　time　of　180　min.　Effect　of　various　operational　parameters　such　as　catalyst　loading,　pH,　and　various　scavengers　was　evaluated　in　detail.　Morever,　in-situ　investigations　were　also　carried　out　in　order　to　determine　the　active　species　and　hence　the　mechanism　for　catalytic　reactions.　These　results　for　dye　detoxification　and　corresponding　reaction　mechanism　suggested　the　synthesized　metal　oxides　as　promising　candidates　for　real　toxic　water　wastes　cleanup　applications.
