Photocatalytic degradation is an effective method to alleviate environmental pollution which is caused by organic pollutants. The expanding natural contamination has attracted the overall scientists to deal with the advancement of photocatalyst effectively depends on semiconductor for the treatment of defiled water assets by different natural poisons that are delivered from numerous industries. In this work, the research progress of properties and applications of photocatalytic and antimicrobial activities and understanding of the toxicity mechanisms of different metal oxide nanoparticles are reviewed. The metal oxide nanoparticles are a wide band hole semiconductor that can be eager to create electron opening sets when transmitted with light. Photographs are an actuated electron opening that instigates power hydrogen, oxygen, and debases inorganic/natural/organic mixes to make power. This review aims to examine the wide biological and mechanisms of photocatalytic degradation and antimicrobial applications.

AbstractA bulk scale process is implemented for the production of nanostructured film composites comprising unary or multi-component metal oxide nanoparticles dispersed in a suitable polymer matrix. The as-received nanoparticles, namely Al$$_2$$ 2 O$$_3$$ 3 , SiO$$_2$$ 2 and TiO$$_2$$ 2 and binary combinations, are treated following specific chemical and mechanical processes in order to be suspended at the optimal size and composition. Subsequently, a polymer extrusion technique is employed for the fabrication of each film, while the molten polymer is mixed with the treated metal oxide nanoparticles. Transmission and reflection measurements are performed in order to map the optical properties of the fabricated, nanostructured films in the UV, VIS and IR. The results substantiate the capability of the overall methodology to regulate the optical properties of the films depending on the type of nanoparticle formation which can be adjusted both in size and composition.
