Selective Oxidation of Aromatic Alcohols to Aldehydes Catalyzed by HKUST-1-Derived Cu-Based Carbon Material and TEMPO

• • Achieved 99.2% conversion of benzyl alcohol and 94.1% yield of benzaldehyde under mild conditions (100 °C, 0.5 MPa O2, 1 h), demonstrating high efficiency for selective oxidation. • • The H-Cu/C catalyst, derived from HKUST-1, features Cu(0) nanoparticles dispersed in a carbon matrix with island-like Cu2O active sites, ensuring stability and activity. • • The catalytic system shows broad substrate scope: over 99% conversion and above 95% aldehyde yield for various substituted aromatic alcohols, including electron-donating and electron-withdrawing groups. • • Catalyst regeneration via H2 reduction allows reuse without significant activity loss, enhancing economic viability for industrial application.
