• activated carbon (AC) exhibited high efficiency in glucose oxidation [25]. The full defunctionalization at higher temperature usually induces an increase in particle size and decrease of the catalytic activity [26]. Benzyl alcohol oxidation is a model reaction generally used to test the catalytic activity
