Mesoporous aluminosilicate molecular sieves have been synthesized using K-feldspar, a natural ore rich in silicon and aluminum sources, as starting material. In this method, the mixture of K-feldspar and K 2 CO 3 with mass ratio of 2:3 was first calcined at 880°C for 1.2h. The calcined materials were then dissolved in water together with cetyltrimethylammonium bromide as structure-directing...
