The presence of persistent, difficult to degrade pharmaceutical compounds in wastewaters is a significant environmental concern. While heterogeneous photocatalysis can range compounds, as technology, it yet be applied. Current research on for removal focused the development photocatalytic materials that are both efficient photocatalysts and solar driven well combine adsorption photocatalysis. f...

Photocatalysis has been widely applied to solar-energy conversion and environmental purification. Photocatalyst, typically titanium dioxide (TiO(2)), produces active oxygen species under irradiation of ultraviolet light, and can decompose not only conventional pollutants but also different types of hazardous substances at mild conditions. We have recently started the study of photocatalytic dec...

Plasmonic enhancement for electron–hole separation efficiency and visible light photocatalysis was achieved by Pd nanocube decoration on a ZnO nanolayer coated onto electrospun polymeric (polyacrylonitrile (PAN)) nanofibers. Since exciton formation and sustainable electron–hole separation have a vital importance for realizing better solar energy in photovoltaic and photocatalytic devices, we ac...

Based on the TiO2 photocatalysis mechanism, a new method of simultaneous desulfurization and denitrification from flue gas was proposed. Preparation of TiO2 photocatalyst, design of photocatalysis reactor and influencing factors for simultaneous removal of SO2 and NO, and removal mechanism of SO2 and NO were studied. After the optimal values of concentration of O2 in flue gas, the relative humi...

Methylthionine Chloride (MTC), commonly known as methylene blue, is a substance widely used in medical and clinical industry indicator, various diseases treatment diagnostic. When MTC discarded out of the organism, it becomes residue which ends wastewater plants not treated or removed properly because has synthetic origin, providing with stability chemical structure difficult to break. In prese...
