摘要： A macroporous sodium transition metal silicate material includes a composition represented by AaM1bM2cXdOe, wherein A is sodium or a mixture of sodium with lithium and/or potassium; M1 is one or more transition metals; M2 is one or more metals and/or metalloids; X is silicon or a mixture containing silicon and one or more elements selected from phosphorus, boron and aluminium; a is >0; b is >0; c is ≧0; d is ≧1; and e is ≧2. A method of forming the macroporous sodium transition metal silicate material includes mixing one or more transition metal precursor materials in a solvent to form a transition metal mixture; adding one or more silicate precursors to the transition metal mixture to form a precursor mixture; raising the pH of the precursor mixture to form a precipitate; stirring the mixture; aging and drying the mixture; washing the mixture; and drying.
