Growth of Carbonaceous Nanomaterials over Stainless Steel Foams. Effect of Activation Temperature

Some of the problems that occur during the operation of chemical reactors based of structured catalytic substrates, as monoliths, foams, membranes, cloths, fibres and other systems, are related to the preparation of long term stable coatings. Frequently, the deposition of the catalytic layer is carr...
