The relatively cheap and abundant Ni as a catalyst for hydrodeoxygenation (HDO) of biomass lignin-derived phenolics at 350 °C and atmospheric pressure suffers from unfavorable C-C hydrogenolysis toward CH₄ with a lower direct deoxygenation (DDO) activity. Herein, we demonstrate that the activity and selectively of Ni for HDO of m-cresol can be modified through the differences of strong metal-suppo ...
