More Information
Summary:The invention belongs to the technical field of a gold catalyst, and particularly relates to a preparation method of a loaded gold catalyst adopting layered composite hydroxide as a precursor. The preparation method comprises the following steps: mixing chloroauric acid, magnesium metal salt and aluminum metal salt, synthesizing the gold-containing layered composite hydroxide in a co-precipitating method, then adopting the composite hydroxide as the precursor, and in-situ preparing gold nano particles in a liquid-phase reduction way, to prepare the gold catalyst. The content of gold in the catalyst is 0.5 to 10.0 percent by weight. The method is moderate in reaction condition, simple in process, convenient to operate, good in repeatability, easy for realizing the mass production and good in application prospect.
