Abstract:
The present invention relates to the technical field of synthesis of catalysts and adsorbents. Disclosed are a Zn-based ternary hydrotalcite and a preparation method therefor and an application thereof, and a Zn-based ternary composite metal oxide and a preparation method therefor and an application thereof. According to the preparation method for the Zn-based ternary hydrotalcite, the characteristic that hydrotalcite is flexible and adjustable in composition is ingeniously utilized, and metal ions having similar radiuses and same charges are used for replacing cations on a hydrotalcite laminate to prepare a Zn-based ternary hydrotalcite having flexible and adjustable composition and a corresponding composite metal oxide thereof. During the preparation, high-temperature calcination treatment is carried out, so that the prepared Zn-based ternary composite metal oxide has relatively high thermal stability. The preparation process is simple, the synthesis condition is mild, the cost is low, and large-scale production is facilitated; the Zn-based ternary hydrotalcite and the Zn-based ternary composite metal oxide thereof have relatively strong adsorption capacity; and thus, the Zn-based ternary hydrotalcite and the Zn-based ternary composite metal oxide thereof have great application value in the fields of heterogeneous catalysis and environmental protection.
