Gas‐Phase Hydrodeoxygenation of m‐Cresol Using Isopropanol as Hydrogen Donor Over a Ni‐Supported Catalyst

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Continuous‐flow hydrodeoxygenation of m‐cresol assisted by catalytic transfer hydrogenation (CTH‐HDO) was carried out at 300°C and atmospheric pressure over a Ni/SBA‐15 catalyst, using isopropanol as a renewable hydrogen donor. Under optimized conditions, a toluene selectivity of 56% was achieved, highlighting the potential of this approach as a safer ...
