Cu and Ni dual-doped ZnO nanostructures templated by cellulose nanofibrils for the boosted visible-light photocatalytic degradation of wastewater pollutants

Abstract

Cu and Ni dual-doped nano-ZnO particles immobilized on cellulose nanofibrils were developed for boosting the photocatalytic performance towards the degradation of various wastewater pollutants under blue light irradiation.

Role of N-Rich Coordination Environment in Metal–Organic Frameworks for Enhanced Photocatalytic Dye Degradation

“…This dye not only pollutes the water but is also mutagenic and carcinogenic to human health. Therefore, to remove MB dye from polluted water; various treatment processes such as reverse osmosis, coagulation, electrochemical decomposition, oxidation, filtration, ion exchange, and photocatalysis are used extensively. − Among all, the photocatalysis method got attention because of its simple and efficient process to degrade the dyes. , So far, several metal oxides (ZnO, WO 3 , and Fe 2 O 3 ), metal sulfides (CdS, ZnS, WS 2 , and MoS 2 ), mixed oxides, and sulfides of semiconductor have been employed for photodegradation of many organic contaminants in aqueous and gaseous phases. − However, these catalysts are susceptible to low energy consumption efficiency associated with the problems of easy clustering and electron–hole recombination. Therefore, developing novel photocatalysts capable of dye degradation with high efficiency, low cost, and acceptable stability under visible light is still a challenge.…”
