of Technology2. Institute of Coal Chemistry,Chinese Academy of Sciences摘 要:Monometallic catalyst Pt/SAPO-11 was prepared by impregnation method.Bimetallic catalysts LaPt/SAPO-11 or CePt/SAPO-11 was prepared by sequential impregnation method.The catalysts were characterized by X-ray diffraction(XRD),nitrogen adsorption,temperature-programmed desorption of ammonia......
University, Changsha 410083, China) Abstract: The quasi-3D C/C composites with rough laminar (RL) and smooth laminar(SL) pytolytic carbon were fabricated by needled felt through CVI and impregnation with liquid pitch and resin, and their friction and wear properties under braking pressure of 0.6MPa and worn mechanism were studied. The results show that C/C composites by resin impregnation after......
Preparation and Characteristics of Rare Earth Loaded Titanium Dioxide 王艳1,张俊平1,戚慧心1 (1.Chemistry Department, Beijing Normal University, Beijing 100875, China) Abstract:Composite oxide catalysts Eu/TiO2, Ce/TiO2, Y/TiO2 (RE/TiO2) were prepared by impregnation method and characterized by means of UV-Vis spectroscopy, TEM and BET. The results indicate that the size of TiO2 has different effect......
Study on Modification of Sm2O3 by Ni/Sepiolite Catalyst 李松军1,罗来涛1,邓庚凤1 (1.Institute of Applied Chemistry, Nanchang University, Nanchang 330047, China) Abstract:A series of Ni-Sm/sepiolite catalysts were prepared by impregnation. The modification of Sm2O3 for Ni/sepiolite was investigated by TPR, XPS and poisoning of CS2, respectively. The results indicate that the addition of Sm2O3 improves......
, China Received 8 September 2019; accepted 30 April 2020 Abstract: A novel Sb2O3/Sb2S3/FeOOH photoanode was fabricated via a simple solution impregnation method along with chemical bath deposition... that the surface of Sb2O3/Sb2S3 thin films becomes rough after the immersion in the FeCl3 solution. The optimized impregnation time is found to be 8 h. The FeOOH co-catalyst loaded Sb2O3/Sb2S3 electrode......

for Pd catalysts, were prepared by an impregnation method. It was found that the CexY1-xO washcoats had better adhesion and higher adsorption efficiency of H2PdCl4, and the optimal component......
catalysts by impregnation method. The catalytic properties and characterization of CeO2, CuO/CeO2 and Cu/CeO2 catalysts were examined by means of a microreactor-GC system, HRTEM, XRD, TPR and XPS techniques......
Effect of La2O3 on Methanation of CO and CO2 over Ni-Mo/γ-Al2O3 Catalyst WANG Ji-jun1,WANG Min-wei2,LUO Lai-tao1,LI Feng-yi1 (1.Institute of Applied Chemistry, Nanchang University, Nanchang 330047, China;2.Department of Chemical Engineering, Nanchang University, Nanchang, 330029, China) Abstract:A series of Ni-Mo/γ-Al2O3 methanation catalysts containing La2O3 were prepared by impregnation......
of La3+ and Ba2+ modified NaY zeolites were synthesized through different impregnation procedures. Lactic acid dehydration to acrylic acid was selected as a probe reaction to test the catalytic... and CO2-TPD. The characterization results demonstrated that the samples synthesized by two-step impregnation had more medium acid and base sites inducing better catalytic performance. Moreover, compared......
