Abstract

The La nanorod and cobalt-manganese spinel were synthesised by an improved sol–gel technique for the selective oxidation of alcohols. The active sites of the catalyst were demonstrated using parameters and a recycling study. Moreover, the catalyst was characterized by Raman spectroscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectra, X-ray diffraction, and surface analysis to examine the impact of La addition on the structural and morphological characteristics of CoMn₂O₄. La is introduced into CoMn₂O₄, which decreases the activation energy; therefore, CoMn_2-XLa_XO₄ selectively oxidizes alcohol at lower temperatures. Higher benzyl alcohol to benzaldehyde conversion was observed for the CoMn_1.96La_0.04O₄ catalyst. The catalyst was further also examined for the selective oxidation of other alcohols. The various commercially important substrates like 2-bromo benzyl alcohol, furfuryl alcohol, etc. undergo selective oxidation using a catalyst was also been investigated. The mechanistic aspects of the catalyst with active sites have been explained using Raman and ATR-FTIR adsorption study.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
