Nanoceria as an Efficient and Cost-Effective Metal-Free Catalyst for the Oxidation of Alcohols.

ABSTRACT: This study investigates the catalytic properties of nanoceria for the liquid-phase oxidation of aromatic and aliphatic alcohols using t-butyl hydroperoxide as an oxidant without the need for base or supported noble metals. The morphology, reducibility, and reversible H₂ adsorption characteristics of ceria were comprehensively studied using X-ray diffraction, BET, HAADF-STEM, H₂-TPR, H₂-TPD, and X-ray photoelectron spectroscopy. Radical formation was interrogated by electron paramagnetic resonance (EPR) using dimethyl pyrrolidine N-oxide (DMPO) and N-tert-butyl-α-phenylnitrone (PBN) as spin traps, complemented by atomistic simulations to elucidate the influence of trap and radical adduct adsorption on the catalysts on radical abun
