Catalytic oxidation of carbon monoxide (CO) is of great importance in many different fields of industry. Until now it still remains challenging to use non-noble metal based catalysts to oxidize CO at low temperature. Herein, we report a new class of nanoporous, uniform, and transition metal-doped cerium (IV) oxide (ceria, CeO2) microsphere for CO oxidation catalysis. The porous and uniform micr...

Ni/CeO2–Al2O3 with bimodal porous structure and two different CeO2 concentrations (low: 5 wt% high: 15 wt%) were prepared by the refluxed co-precipitation method characterized N2 physisorption, XRD, TPR, H2-TPD, CO2-TPD. Catalysts tested in combined steam dry reforming of methane (CSDRM) at atmospheric pressure, 600°C–700 °C CH4: CO2: H2O = 1: 0.48: 0.8, order to prepare synthesis gas H2:CO rat...

The distance between catalytic sites (Ni) and sorbents (CaO) on the performance of integrated CO2 capture utilization (ICCU) process is crucial important because demonstrate a dramatic volume increase during carbonation reaction (1st stage ICCU) sequentially cover retard conversion (2nd ICCU). Herein, we synthesized various Ni/CaO-based dual functional materials (DFMs) with different distances ...

Developing low-temperature nickel-based catalysts with good resistance to coking and sintering for dry reforming of methane (DRM) is great significance. In this work, Ni (5 wt%) CeO2 were supported on SBA-15 porous material by glycine-assisted impregnation method obtain Ni-CeO2/SBA-15-G catalyst. XRD TEM results showed that the addition glycine can effectively promote dispersion NiO in pores SB...

CO2 methanation was studied over monometallic catalyst, i.e., Ni, Fe and Co; on CeO2-Cr2O3 support. The catalysts were prepared using one-pot hydrolysis of mixed metal nitrates ammonium carbonate. Physicochemical properties the pre- post-exposure characterized by X-Ray Powder Diffraction (XRD), Hydrogen Temperature Programmed Reduction (H2-TPR), Field Emission Scanning Electron Microscope (FE-S...

Abstract Experimental and theoretical modeling on low-temperature dry methane reforming over Ni-containing CeO2 rods was studied. The catalyst characterized by means of N2 physisorption, in-situ XRD, TPR H2 chemisorption techniques. characterization studies revealed the distortion flourite structure due to Ni incorporation. Lattice expansion (due reduction) contraction oxidation) suggest revers...

Valorization of lignin is essential for the economics of future lignocellulosic biorefineries. Lignin is converted into novel polymer building blocks through four steps: catalytic hydroprocessing of softwood to form 4-alkylguaiacols, their conversion into 4-alkylcyclohexanols, followed by dehydrogenation to form cyclohexanones, and Baeyer-Villiger oxidation to give caprolactones. The formation ...

Non-thermal plasma (NTP) catalysis is a promising technology for CO2 valorization with renewable H2, in which catalyst design one of the key aspects to progress hybrid technology. Herein, bimetallic NiCo supported on CeO2 catalysts, that is, NiCo/CeO2, were developed less metal loading ∼2 wt % using mechanochemical synthesis NTP-catalytic methanation. During synthesis, different addition orders...
