The production of formic acid (FA) from lignocellulose and its derived sugars represents a pivotal upgrading reaction in biorefinery. This work prepared Mn-Mo doped carbon nanotube composite catalyst for the catalytic oxidation glucose into FA an O2 atmosphere, under extremely low Mn (3.27%) Mo (0.40%) loading conditions, displaying comparable performance with traditional vanadium-based suffering toxicity issues. It was confirmed that doping led to formation MnMoOX increased contents low-valence species (Mn2+ + Mn3+), lattice oxygen (Olatt), surface adsorbed (Oads) based on various characterization methods, such as XRD, XPS, TEM ICP, which were beneficial improve performance. maximum yield 58.8% could be achieved over Mn9Mo1OX@MWCNT after 6 h at 140 °C, far more than obtained undoped MnOX@MWCNT (14.5%) identical conditions. Glyoxylic arabinose identified two main intermediates, suggesting transformation involved different paths. proved manganese-based green alternative via oxidation.
