据英国 New Scientist 1997年4月5日报道,美国和荷兰的化学家发现胶体变硬时,其内部会产生许多孔隙。这种多孔的胶体可作为分子筛使用,以分离不同的化学物质,或者在工业生产中用作加快反应进行的催化剂。多年来化学家一直使用沸石来分离化学物质或作为催化剂,这是因为沸石中 According to the British New Scientist reported on April 5, 1997, chemists in the United States and the Netherlands found that when the colloid hardens, many pores are formed inside. This porous colloid can be used as a molecular sieve to separate different chemicals or used as a catalyst in industrial processes to speed up the reaction. For many years chemists have used zeolites to separate chemicals or act as catalysts because zeolites
