Controlled hydrodeoxygenation of lignin-derived anisole over supported Pt on UiO-66 based-catalysts through defect engineering approach

Enhanced transformation of CO2 over microporous Ce-doped Zr metal–organic frameworks

“…The peak with the lower BE at 530–531.0 eV is associated with the lattice oxygen, while the peak with higher BE at 531.5–531.9 eV can be ascribed to the oxygen in BDC ligand, and the one at 533.1 eV representing the vacancy oxygen. 52–54 It is worth noting that the position of the lattice oxygen in the samples is located at 531.9 eV for Zr-MOF, which shifts towards lower values (531.7 eV) after incorporating Ce into the framework. This result indicates that the Ce has been successfully incorporated into the Zr-MOF framework, leading to an altered electronic structure of the O atoms in the lattice due to different electron-withdrawing effect of Ce and Zr.…”

Bimetallic Niobium-Based Catalysts Supported on SBA-15 for Hydrodeoxygenation of Anisole

“…Using noble metals, a considerable hydrogenation activity has been reported with good stability, obtaining cyclohexane as the main product. 36 Similarly, the use of supported nickel catalysts has demonstrated a good hydrogenation capability at high temperature and pressure. 37 Also, the addition of promoters like zinc or gallium to nickel-based catalysts has shown an enhancement of the selectivity to aromatics.…”

“…These three compounds comprise a large fraction (30%–40%) of lignocellulosic biomass-derived bio-oil, and the C–O bond is difficult to break. , Anisole hydrodeoxygenation has been studied over several bifunctional catalysts. Using noble metals, a considerable hydrogenation activity has been reported with good stability, obtaining cyclohexane as the main product . Similarly, the use of supported nickel catalysts has demonstrated a good hydrogenation capability at high temperature and pressure .…”
