Enhanced photocatalytic activity of graphitic carbon nitride based metal oxides and tungstate nanocomposites for treating textile effluents

Abstract

Recently, photocatalytic innovation has drawn much attention in newlineenvironmental newlineremediation newlineand newlinesustainable newlinedevelopment. newlineWater newlinecontamination has become one of the major issues, as it is suggested to play a newlinerole in several chronic diseases. It is essential to address the treatment of newlineindustrial effluent to avoid water contamination with utmost urgency. Many newlineindustries that use dyes, leave colored wastewater in the effluent. The release newlineof such water into normal streams and waterways from various industries has newlinea serious impact. Treatment efficiency is one of the most imperative to be newlineaddressed. Although several strategies have been employed, photocatalysis newlineeffectively treats industrial effluents without producing any toxic substance. newlineThe rapid progress in nanoscience has accelerated the development of a better newlinephotocatalyst for the treatment of industrial effluents. Among the high-level newlineoxidation processes, photocatalysis by semiconducting materials has become newlinea leading technology in environmental remediation due to its minimum newlineenergy consumption, chemical utilization, and low cost. newlineSeveral photocatalytic materials have been studied for their newlinephotocatalytic efficiency. Oxide and tungstate materials have been mainstay newlinephotocatalysts because of their high stability and highly tunable electronic newlineproperties. Among them, CeO2, ZrO2 SnO2, and Ce2(WO4)3 are multivariate newlinefunctional materials in various applications such as photocatalysis and dye newlinesensitized solar cells, gas sensing, solid oxide fuel cells and optical devices. It newlinecan be used as an effective catalyst for the removal of environmental pollution newlinedue to its outstanding properties such as good oxygen storage capacity, newlineoxidation, reduction (redox property), hydrogenation, strong absorption of newlinelight, high surface area, structural stability, etc. newline
