This study reports the thermochemical transformation of lignin model compounds using nanoparticle organic hybrid materials (NOHMs). NOHMs have recently been developed as an emerging class of self-suspended nanoparticle solvent systems created by ionically or covalently grafting organic oligomers or polymers (canopy) onto surface-modified inorganic nanoparticles (core). Because NOHMs exhibit negligible vapor pressure with the ability to tailor physicochemical properties, they could be a promising catalytic solvent for the lignin thermochemical conversion process. The thermochemical conversion of lignin model compounds was achieved with the synthesized NOHM at an elevated temperature of 473 K, and the results were compared with the case of the ionic liquid [EMIM][ESO4]. The fractured moieties of the lignin model compounds were qualitatively identified by ATR FT-IR and 2D COSY NMR spectroscopies. The results indicated that the NOHM decomposed the C–O and/or C–C bonds of lignin model chemicals more efficiently than [EMIM][ESO4].

新型液体状纳米颗粒有机杂化溶剂对木质素模型化合物进行热化学解聚的光谱研究
这项研究报告了使用纳米颗粒有机杂化材料（NOHMs）对木质素模型化合物的热化学转化。NOHMs最近已发展成为一种新兴的自悬浮纳米颗粒溶剂系统，该系统通过将有机低聚物或聚合物（冠层）离子或共价接枝到表面改性的无机纳米颗粒（核）上而制得。由于NOHMs的蒸气压微不足道，并且具有调节理化性质的能力，因此对于木质素热化学转化过程，它们可能是很有前途的催化溶剂。用合成的NOHM在473 K的高温下实现木质素模型化合物的热化学转化，并将结果与离子液体[EMIM] [ESO 4 ]的情况进行比较。]。木质素模型化合物的断裂部分通过ATR FT-IR和2D COZY NMR光谱定性鉴定。结果表明，与[EMIM] [ESO 4 ]相比，NOHM更有效地分解了木质素模型化学物质的C-O和/或C-C键。
