Structural and Catalytic Properties of Model Supported Nickel Catalysts
published in Aduonce ACS Abstracts, January 1, 1994. 0022-36S4/94/2098-124S%04.S0/0 nation at present. Martini2 and Goodmani3 have suggested that the activity of different crystal planes toward hydrogenolysis is responsible for the observed variations in activity with metal particle size. Single-crystal surface science studies have shown these structure-sensitive reactions to proceed more rapid...
متن کاملThe Kinetics of Methanation on Nickel Catalysts
An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, and in a gradientless recycle reactor (Berry) over a range of total pressures, reactant concentractions (H2/CO ratios), and temperatures. The kinetics of methanation were foun...
متن کاملAntibacterial activity of nickel and nickel hydroxide nanoparticles against multidrug resistance K. pneumonia and E. coli isolated urinary tract
Objective(s): Antibacterial materials are so significant in the textile industry, water disinfection, medicine, and food packaging. Unfortunately, organic compounds for sterilization show toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. Materials and Methods: Nickel and nickel hydroxide nanoparticles (NiNPs ...
متن کاملStudy of nonlinear optical properties of Carbon nanotubes synthesized by Nickel and Nickel-Cobalt catalysts using Z-scan technique
The nonlinear optical properties of carbon nanotubes (CNTs) have been studied by using the Z-scan technique. Experiments are performed by CW second harmonic of Nd-YAG laser at 532 nm wavelength with a power of 40 mW. The samples are synthesized by the chemical vapor deposition (CVD) method in the presence of Nickel and Nickel-Cobalt catalysts. In this work, for the first time, effect of the typ...
متن کاملEffect of Nickel Particle Size on Alumina Supported Nickel Catalysts for p-Nitrophenol Hydrogenation
The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated over alumina supported nickel catalysts prepared by impregnation reduction method and mechanical mixing method. The catalysts were characterized by XRD and FESEM. The results show that the nickel particle diameter of alumina supported nickel prepared by impregnation reduction method (denoted as Ni/Al2O3) is slightly ...
