DOI: 10.1016/j.ces.2019.115201

Abstract: Abstract Diesel oxidation catalysts (DOC) for abatement of CO and hydrocarbon (HC) emissions are commonly based on PtPd/CeO2/Al2O3 formulations. PdPt/CeO2-ZrO2 or Pd/zeolite materials are also used in passive NOx adsorbers (PNA) that capture nitrogen oxides… read more here.

DOI: 10.3390/ma14195470

Abstract: NiWAu trimetallic nanoparticles (NPs) on the surface of support Al2O3-CeO2-TiO2 were synthesized by a three-step synthetic method in which Au NPs were incorporated into presynthesized NiW/Al2O3-CeO2-TiO2. The recharge method, also known as the redox method,… read more here.

DOI: 10.3390/ma15196780

Abstract: To achieve sulfur content in gas oil at a near-zero level, new catalysts with improved hydrogenation functions are needed. In this work, new Ni-Mo-Mo hydrodesulfurization (HDS) catalysts supported by Al2O3-CeO2 materials were synthesized to evaluate… read more here.

DOI: 10.3390/molecules25204644

Abstract: Au, Pt, and Pt-Au catalysts supported on Al2O3 and CeO2-Al2O3 were studied in the oxidation of dichloromethane (DCM, CH2Cl2). High DCM oxidation activities and HCl selectivities were seen with all the catalysts. With the addition… read more here.
