Glycerol molecules can be selectively converted into 1,2‐propanediol in water by the way of Ni‐based Great‐Wall Catalysts with Beacon‐like macropores and Passage‐like mesoporous channels. Otherwise, an amount of by‐product lactic acid was produced via rearrangement from glycerol. More details are discussed in the article by Zhang & Ma et al. on page 439–444.
