摘要：

In the last years the interest in new synthetic and natural titanosilicates has increased. Due to the tunable pore diameter and other distinct characteristics, these materials can be utilized for commercially important separations of gas mixtures of similar size molecules, catalysts and removal of radioactive elements from nuclear waste. However, from the point of view of industrial synthesis, scale-up complicated technology and high cost of the agents are limiting factors, hence it is of interest to research new materials to replace expensive pure titanium precursors and stimulate studies to develop an efficient technology. The results of synthesis of the new nanoporous titanosilicates using cost efficient ammonium oxysulphotitanate are presented. By carefully selecting the titanium sources and synthesis parameters, it is possible to obtain titanosilicate Na2K(Ti-4(OH)(SiO4)(3) analogue of the mineral pharmacosiderite.
