Selectively achieving the photoreduction of carbon dioxide (CO2) to methane (CH4) remains a significant challenge, which primarily arises from complexity protonation process. In this work, we designed metal-vacancy pair sites in defective metal oxide semiconductors, anchor reactive intermediates with bridged linkage for selective produce CH4. As an example, oxygen-deficient Nb2O5 nanosheets are synthesized, niobium–oxygen vacancy demonstrated by X-ray photoelectron spectroscopy and electron paramagnetic resonance spectra. situ Fourier transform infrared monitors *CH3O intermediate, key intermediate CH4 production, during CO2 nanosheets. Importantly, built regulate formation step as spontaneous process, making reduction preferred method. Therefore, exhibit rate 19.14 μmol g–1 h–1, selectivity ∼94.1%.

Toward Value-Added Arenes from Lignin-Derived Phenolic Compounds via Catalytic Hydrodeoxygenation

ACS Sustainable Chemistry & Engineering, Год журнала: 2022, Номер 10(40), С. 13208 - 13243

Arenes are an important class of intermediates in the chemical industry that have been widely applied pharmaceuticals, fuels, synthetic resins, and so on. Given growing demand for arenes unsustainability petroleum-based production pathways, hydrodeoxygenation (HDO) lignin-derived phenolic compounds presents a promising strategy translating lignin materials into value-added arenes. Whereas most HDO catalysts perform low selectivity due to presence competing processes more readily saturate aromatic rings, this Perspective, we first focus on latest advances sustainable from compounds. Furthermore, newest achievements different types their reaction mechanisms involved systematically classified summarized. Lastly, existing challenges, tentative suggestions improvement, future opportunities within attractive field given with aim providing new research ideas stimulating inspiration wide range scientists drive toward carbon-neutral society where biomass resources play major role fuels chemicals.
