Heterogeneous catalyst of pure and Sr doped cobalt chromite styrene selective oxidation to benzaldehyde

Doped metal oxide and mixed metal oxide nanoparticles are currently being considered in all relevant domains for their noteworthy chemical and physical features. Through the use of chemical co-precipitation, both undoped and strontium (Sr) doped CoCr 2 O 4 nanoparticles were successfully synthesized. Transmission electron microscopy, UV-Vis spectra, and photoluminescence studies have all been used to examine the morphological properties of the prepared material system and to discover the precise structure of synthetic materials. Decolorization of 4-Nitrophenol's yellow color is another area of interest in the catalytic characteristics of CoCr 2 O 4 crystals doped with Sr. The catalysts employed were discovered to be readily recyclable and effective catalysts for the oxidation of styrene, with benzaldehyde as the end product.
