Abstract
A method of producing hydrogen comprising hydrolyzing sodium borohydride (NaBH4) with water at a temperature of from about 20 to about 75° C. in the presence of a particulate crystalline nanocomposite catalyst, wherein the ratio by weight of sodium borohydride to the particulate crystalline nanocomposite catalyst is from about 1:1 to about 5:1. The particulate crystalline nanocomposite catalyst comprises: a monoclinic Bi2O3 crystalline phase; a CaSiO3 crystalline phase; and, a graphitic-C3N4 crystalline phase, wherein at least a fraction of the graphitic-C3N4 is in the form of mesoporous nanosheets.
