Efficient hydrogenation of biomass-derived phenol to cyclohexanol over 3D mesoporous silica-supported Ni catalysts in a continuous gas phase conditions

Single‐step conversion of levulinic acid to valeric acid over bimetallic Ni‐Co/H‐ZSM‐5 catalysts

“…As metal content increases, the surface area of catalysts is decreased due to the pore blockage of the support. [34][35] The XRD patterns of calcined 20NiHZ, 20CoHZ, and NiÀ Co/ H-ZSM-5 catalysts were presented in Figure 1. The XRD patterns of H-ZSM-5 show characteristic diffraction peaks of the crystalline H-ZSM-5 zeolite [36,37] For the 20CoHZ catalyst, the diffraction peaks at 2θ of 31…”

“…The surface area of H‐ZSM‐5 is more than supported metal catalysts. As metal content increases, the surface area of catalysts is decreased due to the pore blockage of the support [34–35] …”

Fast catalytic transfer hydrogenation of phenol to cyclohexanol over urea modified Ni@CN nanoparticles

“…7 Moreover, the abundant existence of phenol in natural lignins can provide sufficient feedstocks for the process. Traditional catalytic hydrogenation of phenol can be carried out in the gas 8 or liquid phase 9 using noble metals Pt, 10,11 Rh, 12 and Pd 13,14 or transition metal [15][16][17] catalysts under a H 2 atmosphere, which requires special equipment to store and transport high-pressure H 2 . Moreover, H 2 is also easily explosive and flammable at high pressure or high temperature when combined with air.…”
