双金属催化剂,浸渍法,具体操作,Impregnation,尽量详细一点?我的理解如下:An aqueous solution of HAuCl4·3H2O (2 ml, 5 g dissolved in water (250 ml) ) and an aqueous solution of PdCl2 (0.83 ml, 1 g in water (25 ml)) were simultaneously added to carbon (3.8 g).??2ml 氯金酸溶液和0.83ml 氯化钯溶液加入到器皿中(烧杯、烧瓶等都可以),溶液个人认为应该是过量的,不然会很不均匀(浸渍时很可能有的碳都没接触到溶液,何谈均匀!);至于过量多少,你自己可尝试下,建议过量1.5倍左右吧,个所以要补加部分水,在搅拌状态下,倒入3.8g 碳(粉末),室温或50度左右 蒸干溶液;也可以配好混合溶液后,将溶液倒入已经缓慢搅拌的粉末碳中,再提高搅拌速度。The paste formed was ground and dried at 110 °C for 16 h and then calcined in static air, typically at 400 °C for 3 h.??这一句就没什么悬念了,干燥,然后焙烧,查看更多
