a Control experiments; b NH3-TPD profiles of TiO2-A and Alc-TiO2-A; c Product yields in the alkylation of phenol with 1-propanol over TiO2-A and Alc-TiO2-A; d Product yields in the alkylation of phenol with 1-propanol over TiO2-A and Ni/TiO2-A; e Alkylation of phenol-d6 with 1-propanol. Reaction conditions in c and d: catalyst 0.2 g, phenol 5 mmol, 1-propanol 10 mmol, toluene 25 mL, 300 °C, 4 h, N2 atmosphere. Ni loading of Ni/TiO2-A is 0.5 wt%.
