Photocatalytical Behavior of Metal NPs over Wastewater Treatment

Dear Colleagues,

Process of photocatalysis involves green chemistry, because all energy obtained from photons are utilized into chemical energy. In last few decades, an increase in use of photoreactors was emerged. In present era several modifications were brought for designing a diversified modification in those materials from which semiconductors could be formed, with efficient activity to be employed for photocatalysis of heterogenous materials. Based on modification, band gap, composition and charge transfer process semiconductors to be used in photocatalysis are categorized into four types. These include Z scheme, solid solutions, intrinsic semiconductors and electrical junction created between variant materials termed as heterojunction type II. Photocatalysis involves phenomena of oxidation. In this process, semiconductors capable of photocatalytic activity deteriorate contaminants that are organic in nature. These photocatalysts include zinc oxide and titanium oxide etc. Along with semiconductors, the agent with oxidizing properties like oxygen and a light source was mandatory for effective catalysis. When metal NPs react using photocatalysis their visble driven force and catalytical ehaviour ehanced and they act as promsing catalyzing agents.

This sort of research clinchs the scientiest to work for wastewater treatment because in 21th century the major issue is water contamination. So due to its cost effective this method get more promising effects and results in field of wastewater treatment.  In this special issue we will consider the papers who really hits the terms based on photocatalysis and wastewater treatment.
