The catalytic properties of Pd and Pt supported on woven glass fabrics were explored for liquid-phase hydrogenation of benzaldehyde as a model for three-phase catalytic reaction. The catalysts demonstrated high activity and are suitable materials to be used in reactors with structured catalytic bed. The main characteristics of catalytic bed are discussed.

nano-cufe2o4 catalysts with different cu/fe molar ratios (cunfemo(n+1.5m)) were prepared by hydrothermal method. the thermal decomposition performance of cunfemo(n+1.5m) on cuso4 were determined with tg-dsc method to evaluate its catalytic activity and the roasted product was characterized by xrd. the results showed that cunfemo(n+1.5m) had superior catalytic properties and efficiency to cuso4 ...

h-zsm-5 nano-zeolites were synthesized by hydrothermal method using tetrapropylammonium hydroxide (tpaoh) as a template in the presence of various tpabr concentrations. the effect of different tpabr/tpaoh molar ratios was studied on the catalytic performance of dehydration of methanol to dimethyl ether (dme) in a fixed bed reactor under the same operating conditions (t=300°c, p=1 atm, and whsv=...

Noble metal nanoparticles have been of tremendous interest due to their intriguing size- and shape-dependent plasmonic and catalytic properties. Combining tunable plasmon resonances with superior catalytic activities on the same metallic nanoparticle, however, has long been challenging because nanoplasmonics and nanocatalysis typically require nanoparticles in two drastically different size reg...

The sixty-seven papers in this book are grouped under the following chapters: Esterase Structures, Catalytic Properties of Cholinesterases, Catalytic Properties of Paraoxonases and Related Esterases, Biology of Cholinesterases, Biology of Paraoxonases and Related Esterases, Toxicity and Degradation of Organophosphorus Compounds, Neuropathy Target Esterase, and Miscellaneous. The chapters are pr...

We study equilibrium properties of a catalytically-activated annihilation A + A → 0 reaction taking place on a one-dimensional chain of length N (N → ∞) in which some segments (placed at random, with mean concentration p) possess special, catalytic properties. Annihilation reaction takes place, as soon as any two A particles land onto two vacant sites at the extremities of the catalytic segment...
