ABSTRACT:
A method for forming a reactive medium for removing homogenous and heterogeneous impurities from a fluid is provided which includes forming a uniform oxide layer on all exposed surfaces of a porous metal substrate, depositing at least one layer of carbon on substantially all of the oxide layer formed on the porous metal substrate, depositing a precursor metal species on the carbon layer, and heating the porous metal substrate containing the carbon layer to form active sites on the carbon layer, wherein the active sites include at least partially deoxygenated metal species chemically bonded to the carbon layer. Also provided is a reactive medium for purifying a fluid, the reactive medium comprising a porous inorganic substrate, a layer including carbon and an oxide layer between the porous inorganic substrate and the layer including carbon. The reactive medium further comprises active sites including at least partially deoxygenated metal species, the active sites being bonded to the layer including carbon.
