研究期間:10208~10307;Germanate-based microporous crystalline materials have been the subject of intense research because of their rich structural chemistry and interesting properties. We propose to synthesize metal germanates in the presence of organic templates as structure-directing agents by solvothermal methods, especially for those with large pores or new framework structures. Besides synthesis and crystal structure determination, we also study their thermal stability, ion exchange, and photoluminescence properties.
