Abstract:: ... Lignin-first biorefining constitutes a new research field in which the overarching objective is the prevention of lignin recalcitrance while providing high-quality pulps. For this purpose, the solvent extraction of lignin is performed in the presence of a hydrogenation catalyst, employing H₂ pressure or an H-donor solvent (e.g., 2-propanol), and thus leading to passivation of reactive lignin fragm ...

Abstract:: ... 5-Hydroxymethylfurfural (HMF) is a platform chemical that can be produced from renewable carbohydrate sources. HMF can be converted to 1,2,4-benzenetriol (BTO) which after catalytic hydrodeoxygenation provides a route to cyclohexanone and cyclohexanol. This mixture, known as KA oil, is an important feedstock for polymeric products such as nylons which use benzene as feedstock that is obtained from ...

Abstract:: ... The development of efficient and environmentally friendly catalysts for oxidative reaction is of great importance in applied catalysis. In this work, a simple and environmentally benign approach for highly selective preparation of ε-caprolactone by oxidation of cyclohexanone has been carried out, which employed metal-free mesoporous silica (mSiO₂) nanorods as catalyst under atmospheric pressure. T ...

Abstract:: ... Tandem catalysis, often inspired by biological systems, offers many advantages in the synthesis of highly functionalized small molecules. NH₂-grafted porous C₃N₄ nanosheet with rich N species and surface area of 138 m²/g was fabricated via a NH₃-exfoliation method. After supporting Pd nanoparticles, the resulting bifunctional catalyst (Pd/C₃N₄–NH₂) could catalyze a one-step tandem condensation-hyd ...
