Highly crystalline ZSM-23 zeolite, exhibiting a distinctive dumbbell morphology, was synthesized via a hydrothermal method. Bifunctional catalysts, comprising single metals (Pt or Au) and bimetals (Pt-Au), were successfully prepared by using a positional precipitation method. The hydroisomerization of hexadecane served as a model reaction to assess the catalytic performance arising from the synergistic effects of bimetallic active sites.

Herein, cobalt-reduced graphene oxide (rGO) catalyst was synthesized with a practical impregnation-calcination approach for the selective hydrodeoxygenation (HDO) of guaiacol to cyclohexanol. The synthesized Co/rGO was characterized by transmission electron microscopy (TEM), high-angle annular dark-field scanning TEM (HAADF-STEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, X-ray diffraction (XRD), and H temperature-programmed reduction (H-TPR) analysis. According to the comprehensive characterization results, the catalyst contains single Co atoms in the graphene matrix and Co oxide nanoparticles (CoO) on the graphene surface.

With increasing concern for reducing CO emission and alleviating fossil resource dependence, catalytic transformation of 5-hydroxymethylfurfural (HMF), a vital platform compound derived from C sugars, holds great promise for producing value-added chemicals. Among several well-established catalytic systems, hydrogenation and oxidation processes have been efficiently adopted for upgrading HMF. This Review covers recent advances in the development of thermocatalytic conversion of HMF into value-added chemicals.

Hydrodeoxygenation (HDO) is a promising technology to upgrade fast pyrolysis bio-oils but it requires active and selective catalysts. Here we explore the synergy between the metal and acid sites in the HDO of anisole, a model pyrolysis bio-oil compound, over mono- and bi-functional Pt/(Al)-SBA-15 catalysts. Ring hydrogenation of anisole to methoxycyclohexane occurs over metal sites and is structure sensitive; it is favored over small (4 nm) Pt nanoparticles, which confer a turnover frequency (TOF) of approximately 2000 h and a methoxycyclohexane selectivity of approximately 90 % at 200 °C and 20 bar H ; in contrast, the formation of benzene and the desired cyclohexane product appears to be structure insensitive.
