Abstract : In order to gain more insight into the effects of dislocations and crystal orientation on the catalytic action of metals this research was conducted to determine the effect of dislocation density and crystal orientation on a microscopic area of silver. The results of an experimental investigation to determine the effect of dislocations on catalytic activity are presented. The dislocation density, superficial surface area, hydrogen overpotential area, and mass of a silver catalyst were measured, and the (211) plane of the metal was subsequently used to catalyze the decomposition of formic acid. Although surface preparation of the catalyst was found to have a significant effect on the rate of decomposition, variation in dislocation densities had no observable effect. (Author)
