Abstract
A lanthanum oxycarbonate catalyst, and a preparation method therefor and an application thereof are provided. The lanthanum oxycarbonate catalyst contains a rod-shaped lanthanum oxycarbonate catalyst and a substantially parallelepiped lanthanum oxycarbonate catalyst. The lanthanum oxycarbonate catalyst can be used for efficiently performing a methane oxidative coupling reaction at a relatively low temperature.
Claims26
A lanthanum oxycarbonate catalyst, wherein the lanthanum oxycarbonate catalyst comprises a substantially parallelepiped lanthanum oxycarbonate and a rod-shaped lanthanum oxycarbonate, wherein two adjacent interior angles of the substantially parallelepiped lanthanum oxycarbonate are ∠A and ∠B, wherein 60°<∠A<90° and 170°<(∠A+∠B)<195°.
