Abstract

Monometallic cerium layered double hydroxides (Ce-LDH) supports were successfully synthesized by a homogeneous alkalization route driven by hexamethylenetetramine (HMT). The formation of the Ce-LDH was confirmed and its structural and compositional properties studied by XRD, SEM, XPS, iodometric analyses and TGA. HT-XRD, N-sorption and XRF analyses revealed that by increasing the calcination temperature from 200 to 800 °C, the Ce-LDH material transforms to ceria (CeO) in four distinct phases, i.e., the loss of intramolecular water, dehydroxylation, removal of nitrate groups and removal of sulfate groups. When loaded with 2.5 wt% palladium (Pd) and 2.5 wt% nickel (Ni) and calcined at 500 °C, the PdNi-Ce-LDH-derived catalysts strongly outperform the PdNi-CeO benchmark catalyst in terms of conversion as well as selectivity for the hydrogenolysis of benzyl phenyl ether (BPE), a model compound for the α-O-4 ether linkage in lignin. The PdNi-Ce-LDH catalysts showed full selectivity towards phenol and toluene while the PdNi-CeO catalysts showed additional oxidation of toluene to benzoic acid. The highest BPE conversion was observed with the PdNi-Ce-LDH catalyst calcined at 600 °C, which could be related to an optimum in morphological and compositional characteristics of the support.

摘要

通过六亚甲基四胺（HMT）驱动的均匀碱化路线成功合成了单金属铈层状双氢氧化物（Ce-LDH）载体。通过XRD、SEM、XPS、碘量分析和TGA对Ce-LDH的形成进行了确认，并研究了其结构和组成特性。HT-XRD、N吸附和XRF分析表明，通过将煅烧温度从200℃提高到800℃，Ce-LDH材料会在四个不同阶段转变为二氧化铈（CeO），即分子内水的损失、脱羟基、硝酸根的去除和硫酸根的去除。当负载2.5 wt%的钯（Pd）和2.5 wt%的镍（Ni）并在500℃煅烧时，PdNi-Ce-LDH衍生的催化剂在苄基苯基醚（BPE）（木质素中α-O-4醚键的模型化合物）氢解的转化率和选择性方面明显优于PdNi-CeO基准催化剂。PdNi-Ce-LDH催化剂对苯酚和甲苯具有完全选择性，而PdNi-CeO催化剂会将甲苯进一步氧化为苯甲酸。在600℃煅烧的PdNi-Ce-LDH催化剂上观察到最高的BPE转化率，这可能与载体形态和组成特性的优化有关。
