High-purity, aligned single-walled carbon nanotubes ( SWNTs) were synthesized using Fe/ 13X molecular sieve as catalyst carrier by fluidized bed method. Hexane was used as carbon precursors in the synthesis. The SWNTs were grown using Fe/ 13X molecular sieve soaking of different time. 采用流化床法,以Fe/13X分子筛作为催化剂载体,催化裂解正己烷制备出定向排列的、较纯的单壁碳纳米管。
MCM supported TiO_2 and TiO_2/ Pd Photo-catalysts are prepared with porous material molecular sieve MCM as carrier. 用分子筛MCM多孔材料作载体,制备了负载型MCM-TiO2和MCM-TiO2/Pd催化剂。
