In this work, magnetic CuFe2O4/Ag nanoparticles activated by porous covalent organic frameworks (COF) was fabricated to evaluate the heterogenous reduction of 4-nitrophenol (4-NP).The core-shell CuFe2O4/Ag@COF was successfully prepared by polydopamine moen finney reduction of silver ions on CuFe2O4 nanoparticles, followed by COF layer condensation.
Abstract Background Terrestrial snails, specifically Theba pisana, represent significant agricultural pests in the Mediterranean region, bempresas.com particularly in Egypt.They are gastropods that cause substantial damage to a variety of vegetation, rendering them important agricultural pests that result in economic losses.In response, we have dev
