Traditional and green approaches to the synthesis of copper-containing nanoparticles using chemical reduction

Abstract

The problem of obtaining copper-containing nanoparticles by chemical reduction has been studied. A comparison is made of traditional and “green” approaches to synthesis. The experimental data obtained during the synthesis of copper nanoparticles in the presence of a polymer stabilizer (polyvinylpyrrolidone) and a reducing agent (tert-butylamine-borane), as well as literature data on the synthesis of nanoparticles using plant and conditionally “green” substances (glucose, extracts of Ocimum sanctum and Celastrus paniculatus leaves, Sarcostemma acidum stem). The advantages and disadvantages of these approaches are identified and discussed. It is noted that the industrial applicability of “green” methods is limited due to the need to create completely new production of reagents for synthesis. In addition, the application of green synthesis is difficult due to scalability and standardization issues. Environmental pollution associated with the production of plant extracts also requires additional assessment. It has been established that traditional synthesis methods remain relevant for modern industry, and “green” methods have prospects for use in the distant future.
