The catalytic performance of NiMoAl catalysts derived from layered double hydroxide (LDH) precursors with molybdenum species incorporated into the interlayers was investigated for the hydrodeoxygenation (HDO) of anisole as a model compound of the lignin. The results showed that high dispersion of small Ni nanoparticles with 2–5 nm due to the pinning effect of Mo from Mo7O246− intercalated the LDHs. Due to presence of the oxygen vacancy sites on the molybdenum oxide, the NiMoAl catalysts exhibit higher conversion of anisole than the corresponding NiAl catalyst. The activity for hydrodeoxygenation was enhanced with the increased content of molybdenum species, which can be attributed to the larger amount of acid sites-promoted removal of oxygen from anisole. In addition, the NiMoAl catalysts show higher resistance to deactivation than the NiAl catalyst, and can be broadly applied to other hydrodeoxygenation reactions.

由七钼酸盐插层的层状双氢氧化物制得的NiMoAl催化剂用于苯甲醚的加氢脱氧

研究了在层间掺入钼的层状双氢氧化物（LDH）前驱体衍生的NiMoAl催化剂对木质素模型化合物苯甲醚的加氢脱氧（HDO）的催化性能。结果表明，由于Mo7O246-中Mo的钉扎​​效应，较小的Ni纳米颗粒具有2–5 nm的高度分散性，从而插入了LDH。由于在氧化钼上存在氧空位，因此NiMoAl催化剂显示出比相应的NiAl催化剂更高的苯甲醚转化率。钼物种含量的增加提高了加氢脱氧的活性，这可以归因于大量的酸位促进了从苯甲醚中去除氧。此外，
