Magnetically recoverable Cu₂O–Fe₃O₄@TNT catalytic system for click chemistry in water: multi-component synthesis of 1,2,3-triazoles at room temperature

Abstract

The catalytic performance of Cu2O-Fe3O4@TNT nanocatalyst derived from Fe(III) acetylacetonate, Cu(II) acetylacetonate and hydrogen titanate nanotubes (HTNT) has been investigated for the first time in the click reaction in water...

Cobalt ferrite magnetic nanoceramics as an efficient nanocatalyst for the oxidation of olefins in the presence of molecular O2 as an environmentally safe oxidant

“…2 To overcome this problem, recently, magnetic nanoceramics have been widely used as nanocatalysts, due to their convenient recyclability and high surface area, leading to high loading capacity, high dispersibility, and excellent stability. [3][4][5][6][7][8] Among magnetic nanoceramics, spinel ferrites, especially cobalt and iron compounds, are of great catalytic importance. 9,10 The spinel ferrites play a significant role in many reactions, such as oxidative hydrogenation of hydrocarbons, selective oxidation of carbon monoxide, decomposition of alcohols, and oxidation of olefins.…”

“…In addition, the conceivable purulence of the catalysts in products also limits their use in industry 2 . To overcome this problem, recently, magnetic nanoceramics have been widely used as nanocatalysts, due to their convenient recyclability and high surface area, leading to high loading capacity, high dispersibility, and excellent stability 3–8 .
