I think the shape of the powder and the packing geometry is equally as important as size for varying suppression values . I give a lot of weight to a Cornell report by Peng Chen that catalytic action in nano tubes only occurs at openings and defects - therefore I suspect that catalytic action is a complex recipe where you need to CHANGE both nano geometry and conductivity between parallel surface areas. Grains of nickel powder should fit together to form variations in Casimir geometry between grains. Addition of other powders of different conductive properties could further enhance the gradient of changes in suppression - catalytic action. My point is the inverse geometry we see in the pores of a skeletal catalyst like Rayney Nickel (2- 10 mnm) can be accomplished by much larger grains of powder because it is the formation of "pore like" geometry between the grains which is far smaller than the grain itself.
