银催化剂银催化剂silver catalyst y旧eu一huaJ-银催化剂(silve:Catalyst)以银为主要活性组分制成的贵金属催化剂。西方国家用量每年达100~150t。银催化剂对氧化反应显示出良好活性。 银催化剂的形态有金属(丝网或银粒)型和载体负载型两种。金属型银催化剂用于甲醇氧化制甲醛和乙醇氧化脱氢制乙醛。这两条生产路线虽然很古老，但技术成熟，至今仍在使用。负载型银催化剂最主要的工业应用是乙烯氧化制环氧乙烷，从193。年开发·直适用至今。该催化剂一般采用a一Alz()3作载体，含银量为1。%一3。%。为了改善催化剂的性能，常添加有枷、艳、钙、钡等助催化剂。典型的制备方法是用硝酸银溶液浸渍AI:03载体，然后经热分解制成催化剂。后来发现，经有机银化合物(如烯酮银)中间体再分解，可制得银晶粒更细且分散更好的催化剂，其选择性大幅度提高。此外，载体银催化剂还用于燃料电池作催化电极(Ag/活性炭)及石油化工中甲苯歧化生产对二甲笨(Ag/A12O3)。 (杨汝琳)
