Application of different Nanocatalysts in industrial effluent treatment: A review

The manufacturing, application, and design of chemical processes products that minimize or remove waste the use dangerous toxic reagents are referred to as green chemistry. Green chemistry is made up twelve principles, one which catalysis. role catalysis accelerate reaction by introducing a substance called catalyst. Because their high efficiency, productivity, activity, selectivity, nanocatalysts have recently received many interests. Nanocatalysts characterized surface area volume ratio, well nanoscale forms sizes. One significant applications wastewater purification. bio-synthesized could be used efficiently heavy metals, medicinal, organic, inorganic pollutants from systems. This paper reviews based on noble magnetic nanocatalysts, metal catalysts supported organic polymers, discusses industrial effluent treatment mechanisms.
