Abstract

The rate of sulfur transfer across the gas/solid interface involving H₂S(g) and α-Ag_2+xS surface has been investigated using resistance relaxation measurements at 300°C. The rate of the oxidation reaction incorporating sulfur into Ag_2+x.S has been found to decrease with sulfur activity in the sample as (α_s)^-1/2 while the rate of the reduction reaction corresponding to the sulfur loss is found to increase with the sulfur activity as (α_s)^1/2. The rate-limiting step has been identified to be H₂S + 2e^-= S^2-(ad) + H₂.
