1. a method of modifying for porous substrate, comprises the following steps:

  • Coating at least one layers of metal hydroxides is on a porous substrate, and wherein said porous substrate is porous stainless steel or porousNickel-Based Steel;

    AndCalcination has the porous substrate of layers of metal hydroxides, has continuous phase so that described layers of metal hydroxides is converted into oneMetal oxide layer, formed a modified porous substrate;

    Wherein said metal oxide layer is the oxide of the first metal containing bimetallic ion, and the first metal and secondMetal is different, and the oxide of described first metal is magnesium oxide, aluminium oxide, chromium oxide, lithium oxide, sodium oxide, potassium oxide, oxidationZinc, ferrum oxide, nickel oxide, manganese oxide, calcium oxide, copper oxide or above-mentioned combination in any, and described bimetallic ion is Li+
