Nanocatalyst in remediating environmental pollutants

Abstract

The gradual increase of population and residues excreted from advance industries disturbs our ecological balance. The report of change in climate and environmental pollution is most hot topic around the world. Environmental pollution has become a threat to our life as it may be the root causes of different unwanted diseases. Hence, the degradation of this pollutants are required immediately. However, there are some pollutants which are very hard to degrade and needs more time for remediation. In this process, the novel work of nanotechnology can be applied and the pollutants can be transformed into a harmless one or can be properly remediate. It is possible because of their large surface area, active sites and sufficient functional groups. Besides these, it could transform strong surface complexes with various kinds of pollutants and thereby could efficiently eliminate the pollutants from the aqueous solutions. As a result, nanocatalyst and nanomaterials are generally used for the remediation process. Different kind of nanomaterials including inorganic, carbon materials and polymeric based materials are used in remediation of environment contaminants. Utilizing these novel materials can successfully purified pollutants like heavy metals, dyes, chlorinated organic compounds, organophosphorus compounds, volatile organic compounds, and halogenated herbicides. Furthermore, process like adsorption and photocatalytic reduction of organic pollutants and the adsorption or reduction process of heavy metal ions are usually considered as the one of the major methods to reduce the concentration of pollutants in the surroundings. In context to this, the present review writes up more on enhancement work of nanocatalyst in remediation of environment pollutants and there need for future to bring a clean safety environment.
