In the field of science and technology, Photodegradation is considered as familiar and interdisciplinary due to inclusion of the growth of narrative methods for the fortification as well as preservation of our surroundings. The purpose of this study is to analyse the photocatalytic degradation of complexes include Copper as metal which is prepared by natural edible oils with long chain fatty acids and precise rate of reaction and overall study of photocatalytic degradation of Copper (II) Soya Thiourea complex in which N and S act as donor atoms, as a function of various functioning parameters such as catalyst loading light intensity, reactivity in polar and non-polar solvent. Investigation of comparative performance in percent degradation of Copper Soya soap complexes were also done expected that it will create novel hopes in the pitch of biological applications. Photocatalysis applications in the area of renewable energy and biological activities also will make innovative ideas in the field of biological and pharmaceutical studies.
