Facile Synthesis and Phase-Dependent Catalytic Activity of Cabbage-Type Copper Oxide Nanostructures for Highly Efficient Reduction of 4-Nitrophenol

Selenium and nitrogen co‐doped porous carbon immobilized Ag nanoparticles: A practical heterogeneous nanocatalyst for hydrogenation of nitroaromatics

“…[1] Hence, these compounds can be existed at high levels in industrial effluents and severely threaten the environment and human health because of their high toxicity and nonbiodegradable nature. [2,3] So far, different techniques have been applied to eliminate toxic nitroaromatics from the environment such as photocatalytic degradation, [4] ozonation, [5] adsorption, [6] and catalytic hydrogenation. [7] Among these techniques, catalytic hydrogenation of nitroaromatics into amines is an efficient, simple, and industrially important method, because the relevant products are versatile intermediates and building blocks for the synthesis of polymers, agrochemicals, pharmaceuticals, dyes, pigments, and analgesic and antipyretic drugs.…”

Improved Mechanochemical Fabrication of Copper(II) Oxide Nanoparticles with Low E-Factor. Efficient Catalytic Activity for Nitroarene Reduction in Aqueous Medium

“…In another reported study (entry 2), nanosized CuO, with cabbage-type morphology, was prepared by a nanoprecipitation method and applied toward the reduction of p-nitrophenol into p-aminophenol, showing good catalytic efficiency. 18 CuONPs with an average size of 15.5 nm (entry 3), prepared in two steps with (a) the conversion of CuSO 4 •5H 2 O to Cu(OH) 2 promoted by ashes of Musa balbisiana peel followed by (b) calcination at 300 °C for 2 h, were employed in the reduction of six examples of nitroarenes. 19 The yields of the respective anilines were from 74 to 96%.…”

“…Also, CuONPs have attracted attention as efficient catalysts to promote sustainable chemical transformations. For instance, CuONPs were reported as catalysts for CO 2 electroreduction yielding ethylene, electrocatalytic water oxidation, click chemistry reactions, photocatalytic degradations of organic dyes, dehydrogenation of alcohols, C–N cross-coupling reactions, and nitroarene reduction. − …”

Copper Oxide Thin Film Synthesis, Characterization and Application as Cathode in Photoelectrocatalytic Cell for Methyl Orange Degradation

“…These organic dye pollutants are highly toxic and have considerable detrimental effects on human health, the environment and aquatic ecosystems Ismail et al (2019); Khan et al (2019); Ramezani et al (2019); Sharma and Bhattacharya (2017). Amongst various pollutants, methylene blue and methyl orange are the main ones found in wastewater John et al (2017); Kushwaha et al (2014); Sahu, Satpati, and Mohapatra (2019). Methyl orange (MO) is an intensely colored toxic compound used in textile industry.…”
