Effect of ultra-low amount of gold in oxide-supported bimetallic Au–Fe and Au–Cu catalysts on liquid-phase aerobic glycerol oxidation in water

Low-loaded Au–Fe and Au–Cu supported bimetallic catalysts showed exceptional activity in liquid-phase glycerol oxidation. Strong synergetic effect of Au–Fe (Cu) interaction and Au content tuned the oxidation activity and selectivity of the catalysts.
