The Concentration Effect of Adsorption Nanocomplexes on the Catalytic Activity of Skeletal Nickel in Liquid-Phase Hydrogenation of Sodium Maleate in Aqueous Organic Environments

摘要

The effect of the concentration of adsorption nanocomplexes on the catalytic activity of skeletal nickel in liquid-phase hydrogenation of sodium maleate in 0.01 M sodium hydroxide solution containing 0.11 mol part methanol is studied. The increase in the surface concentration of hydrogen-metal and metal-alcohol nanocomplexes is found to decrease the initial reaction rate and be accompanied by blockading the active catalyst sites involved in the chemical process with methanol molecules.
