Thermochemical and catalytic properties of modified bentonites
Thermochemical properties of bentonites, natural (from three Ukrainian deposits) and modified by physical and chemical methods have been investigated. The three-step mass loss process with two endothermic effects in the ranges of 130–150°C and 500–600°C was observed for all bentonite samples under s...

| description | Thermochemical properties of bentonites, natural (from three Ukrainian deposits) and modified by physical and chemical methods have been investigated. The three-step mass loss process with two endothermic effects in the ranges of 130–150°C and 500–600°C was observed for all bentonite samples under study. These natural and modified bentonites were used as supports for obtaining palladium(II)-copper(II) catalysts for carbon monoxide oxidation. The activity of the catalysts has been found to depend on both the origin of bentonites and the techniques of their modification |
