CuNiAl hydrotalcites supported BiOCl were prepared by one-step synthesis for the selective oxidation of glycerol to glyceraldehyde with H2O2 as oxidant. The prepared catalysts were found to be efficient due to the synergetic catalysis of surface oxygen vacancies, active Cu2+ ions in the HT-lattice and abundant surface -OH groups of catalysts. The optimal glycerol conversion could reach 75.4% with 82.4% of the selectivity to glyceraldehyde. Moreover, the catalyst could be reused at least 6 times, and a possible reaction mechanism was also proposed.
