A method of generating hydrogen gas from the reaction of stabilized aluminum nanoparticles with water is provided. The stabilized aluminum nanoparticles are synthesized from decomposition of an alane precursor in the presence of a catalyst and an organic passivation agent, and exhibit stability in air and solvents but are reactive with water. The reaction of the aluminum nanoparticles with water produces a hydrogen yield of at least 85%.

A system and device for filtering fluids using graphene oxide (GO) is provided. GO-based filters may be used for the efficient removal of microorganisms from organic and aqueous liquids and may be used to prevent fuel biodeterioration. Functionalization of graphene oxide with reactive oxygen functional groups provides physical properties to the GO including high solubility in polar solvents, good colloidal properties, low production costs, low toxicity, and a large surface area which can be decorated with antimicrobial agents including nanosilver. GO may be used as a filtration media for efficient removal of bacteria and to remove small amounts of water from hydrocarbon fuels. The GO filter media may be made of a plurality of GO particles, a structural core coated with GO, a non-porous structural membrane coated with GO, or a filtering membrane coated with GO. A method for sampling impurities found in an environmental sample is also provided.
