We summarize the recent advances, challenges, and perspectives in developing selective catalysts for HDO of phenolics.
Tailoring the graphene-covered Fe with Cs modifies the surface electronic properties of the catalysts such that selective C–O bond cleavage of phenol is achieved in liquid phase by inhibiting the facile tautomerization followed by ring saturation.
High reducible distorted bimetallic sites with medium size in Ni 5 Co 5 -AC promoted the production of cyclohexanol by hydrogenation of anisole and subsequent cleavage of C 6 H 11 O–CH 3 bond.
Non-edible lignocellulosic biomass represents the most abundant source of renewable carbon on Earth. To harness its potential for producing valuable fuels and building blocks for renewable plastics, it is essential to undergo a process that involves the removal of oxygen atoms from its components. This report outlines various methodologies aimed at converting biomass components into fuels and building blocks suitable for renewable plastics. The primary emphasis of the described research lies in leveraging sustainable chemistry and catalysis to valorize biomass into fuels and chemicals.
The work summarized in this presentation builds off of these studies, utilizing atomic-scale modeling to discern the role of Pt-metal and Pt-TiO2-interfacial sites in promoting key C-C bond-breaking, C-O bond-breaking, and (de)hydrogenation steps in acetic acid HDO. By considering Pt(111) and Pt-TiO2-interface surface models, adsorption and reaction energetics calculated by density funcational theory provide fundamental insights into the role of both interfacial sites and oxygen vacancies in promoting desired deoxygenation pathways over undesired decarboxylation/decarbonylation pathways.
