Abstract
A method of carrying out a reaction in a solution catalytically comprising contacting a solid catalytically active material and a solution in which a catalytic reaction is to be carried out wherein the catalytic reaction yields a gas which adheres to the catalyst particles such that as the reaction is substantially complete in the immediate environment of the catalyst, the catalyst migrates to a reactant richer portion.
