Claim 0:
1. A method of controlling an average crystallite size of a composition comprising silver vanadium phosphorus oxide, the method comprising:
selection a reaction temperature and a reaction time;
heating a mixture of vanadium oxide (V2O5), silver oxide (Ag2O), phosphoric acid (H3PO4), and water using microwave energy to the reaction temperature;
holding the mixture at the reaction temperature under microwave irradiation for the reaction time to form the silver vanadium phosphorus oxide composition; and
cooling the silver vanadium phosphorus oxide composition to room temperature, such that the average crystallite size of the silver vanadium phosphorus oxide composition is attained, wherein the average crystallite size of the silver vanadium phosphorus oxide composition is less than about 100 nm, and wherein the silver vanadium phosphorus oxide composition has a surface area of from 5.7 m2/g to 7.5 m2/g, and an atomic ratio of silver to vanadium between 1.96 and 2.
