Pt/Al2O3La2O3 catalysts stable at high temperature in air, prepared using a “one-pot” sol–gel process: Synthesis, characterization, and catalytic activity in the partial oxidation of CH4

Study of Ni Catalysts with Different Al2O3 Supports in the Partial Oxidation of Methane Reaction

“…Methane is the major component of natural gas, which can be processed into various chemicals and intermediates, − including syngas, a valuable platform chemical composed of CO and H 2 . Current syngas production from methane mainly includes three routes, steam reforming of methane (SRM), dry reforming of methane (DRM), and partial oxidation of methane (POM). − As an economical strategy to synthesize syngas from methane, POM is attracting more and more attention due to the small size of the reactor, short time of contact (1–40 ms), low energy consumption, and low equipment investment and production cost. − In recent years, noble metals (e.g., Rh, Pd, Ir, and Pt) and transition metals (e.g., Ni, Co, Fe, and Ru) have been widely investigated for POM reactions. − Among the catalysts, Ni-based catalysts have the advantages of earth abundance and low cost, as well as effectively activating the C–H bond ability. , Unfortunately, sintering and carbon deposition are the main challenges for Ni-based catalysts in the POM reaction, which can result in the deactivation of the catalyst . Therefore, it is necessary to develop novel Ni-based catalysts to inhibit Ni sintering and carbon deposition.…”

“…TMO catalysts are prepared using coprecipitation, 27 sol–gel, 28 hydrothermal, 29 and aerosol pyrolysis methods. 30 When using the aerosol pyrolysis method by controlling the kinds and concentrations of precursors, atomization power, pyrolysis temperature, and gas atmosphere, the as-prepared catalysts have benefits from the doping, nano-engineering, and interfacing.…”
