Abstract: A system and method for reducing nitrous oxides in diesel exhaust with hydrogen and carbon monoxide over a palladium based catalyst. The catalyst comprises a compound represented by the formula: X % Pd—Y % V2O5/Z, where X is between about 0.1 to about 2.0, Y is between about 0.1 to about 7.0, and Z is an oxide support.

Abstract: A composition for hydrogen storage includes a source of hydrogen atoms, a receptor, and a chemical bridge formed between the source and the receptor. The chemical bridge is formed from a precursor material. The receptor is adapted to receive hydrogen spillover from the source.

Abstract: A method for removing organo-nitrogen compounds from liquid fuel includes contacting the liquid fuel with an adsorbent which preferentially adsorbs the organo-nitrogen compounds. The adsorption takes place at a selected temperature and pressure, thereby producing a non-adsorbed component and an organo-nitrogen compound-rich adsorbed component. The adsorbent includes either a metal or a metal cation that is adapted to form ?-complexation bonds with the organo-nitrogen compounds, and the preferential adsorption occurs by ?-complexation.
