Green sol–gel synthesis of CoMnCrO 4 spinel nanoparticles and their photocatalytic application

“…4. Two strong peaks at 617.68 and 499.67 cm −1 are specified to the metal oxide (M–O) vibrations of tetrahedral and octahedral sites in the spinel structure [24]. The presence of hydroxyl group (O–H) on the surface of sample confirms with two broad absorption bands at 3423.83 and 1624.73 cm −1 .…”

A novel magnetic nanocatalyst Fe3O4@PEG–Ni for the green synthesis of 2,3‐dihydroquinazolin‐4(1H)‐ones

“…[14] In addition, magnetic nanocatalysts are studied for the synthesis of various organic compounds [15][16][17][18][19][20][21][22] and the degradation of organic pollutant dyes. [23][24][25] The magnetic properties make them useful to facilitate the separation of the nanocatalyst from the reaction mixture using an external magnet. [26] Usually, 2,3-dihydroquinazolin-4(1H)-ones are prepared using the reductive cyclization of aldehydes or ketones with 2-aminobenzamide in the presence of acid catalysts.…”
