Abstract

The invention discloses a preparation method of environmentally friendly gold-bearing catalyst. Said method includes the following steps: uniformly mixing carrier iron salt solution and gold salt solution, stirring them at 20-80deg.C, using sodium carbonate as precipitant to make precipitation, regulating final pH value to 7-10, continuously stirring for 1.5-4hr, standing still for 2.5-6hr, filtering and drying for 4-24hr at 20-80deg.C so as to obtain the invented catalyst. Said method has no need of washing or roasting. Said catalyst has the strong potency for resisting poisoning of CI-.

Description

technical field

[0001] The invention relates to an environment-friendly preparation method of loaded gold catalyst. Background technique

[0002] Since Haruta reported in 1989 that highly dispersed supported gold catalysts prepared by co-precipitation method had unique low-temperature oxidation activity for CO, gold catalysts have received widespread attention. Compared with highly dispersed supported platinum catalysts, the oxidation activity of gold catalysts for CO is an order of magnitude higher, and the production of precious metals such as platinum and palladium is low, the price is relatively high and is greatly affected by the relationship between supply and demand, while gold reserves are abundant. , the output is nearly ten times that of platinum and palladium, and the price is relatively cheap and very stable, so people began to shift more attention to gold catalysts. Supported gold catalysts also exhibit high catalytic activity in other catalytic reactions (such...
