The synthetic strategy of mixed metal oxide nanoparticle has emerged to be one of the interesting domains in material science. Here carica papya fruit extract assisted synthesis of silver copper oxide is reported via co precipitation method. For the comparative study, using similar precursor material silver copper mixture composite is synthesized using conventional base via coprecipitation method. The composites were subjected to degradation of methylene blue for observation of its efficiency as a photocatalyst. Hydroxyapatite was obtained from fish bones and was used for encapsulating the composite material. The resultant composite was analysed using XRD, SEM-EDS, TEM, XPS and FT-IR techniques. The uncapped composites reported to degrade 90.12 % and 91.5 % of methylene blue within 60 min. The conventionally synthesized composite degraded 30 ppm Bibersch scarlet up to 86.04 % in 40 min under assistance of sunlight. The encapsulated composite was successful in degradation of Brilliant green 89.9 % in 140 min and eosin yellow 92.2 % in 120 min. The catalyst in encapsulated and un encapsulated form reveals its efficiency to be a potential photo catalyst.
