Size effect of Ru particles on the self-reforming-driven hydrogenolysis of a lignin model compound

Abstract

Particle size always has a great influence on catalytic performance. In this work, we investigated the size effect of Ru colloids on the self-reforming-driven hydrogenolysis of lignin model compound by...

Hydrogen‐transfer strategy in lignin refinery: Towards sustainable and versatile value‐added biochemicals

“…Wang et al executed a study that amalgamated various steps such as dehydrogenation of aliphatic hydroxyl groups, hydrogenolysis of ether and methoxyl bonds, and hydrogen generation via methanol autothermal reforming, with Pt/NiAl 2 O 4 serving as the catalyst. [184] This holistic strategy led to the high-selectivity production of 4-alkylphenol. Furthermore, the self-reformingdriven methodology proved to be adaptable, as evidenced by its application to the conversion of natural depolymerized lignin oils and birch lignin.…”

Catalytic self-transfer hydrogenolysis of lignin over Ni/C catalysts

“…Wang's group used NiAl 2 O 4 loading with various noble metals to produce alkylphenol from lignin by self-reforming-driven depolymerization and hydrogenolysis, and found that demethoxylation is the rate-determining step in the whole process. [17][18][19] Rong and Li reported the highly selective conversion of guaiacol to phenol in pure water by a versatile nano-porous Ni catalyst, and the mechanism showed that the initial hydrogen source came from water splitting on the surface of the Ni catalyst, and the subsequent aqueous phase reforming of methanol generated more hydrogen and further accelerated the hydrodeoxygenation process. 20 Our group proposed self-supported hydrogenolysis (SSH) of aromatic ethers to produce arenes using the methoxy group as the hydrogen source over RuW/SiO 2 .…”

“…22 These articles used water as the reaction medium, which is a cheap, non-toxic and environmentally friendly reaction medium. [15][16][17][18][19][20][21][22] The reported works on the STH process are based on precious metal catalysts. However, the resources of precious metals are very limited, and mining and purification release large amounts of CO 2 compared with non-precious metals.…”
