Disclosed are hierarchically porous carbon materials with a plurality of discreet nanoparticles dispersed on their carbon phase. The materials possess a continuous network of pores that spans the porous material, permitting the flow of fluids into and through the material. The porous materials can be used as heterogeneous catalysts.

A method of treating water to oxidize organic contaminants comprises heat transfer system includes heating liquid water to a temperature of at least 190 F. at a pressure to keep the heated water in a liquid phase, and contacting the heated water with oxygen and an oxidation catalyst including a noble metal on a porous support comprising a bi-modal pore size distribution including pore sizes from 1 nm to 20 nm and pore sizes from 100 nm to 1000 nm. The resulting catalytic oxidation of the organic contaminants results in the release of gaseous reaction products resulting from the oxidation reaction, which are separated from the treated water in a phase separator to produce a treated water final product.
