Abstract
Disclosed herein is a catalyst composite containing a perovskite-oxide and an oxide support, methods of preparing a catalyst composite containing a perovskite-oxide and an oxide support, and the use thereof for CO2 conversion by a reverse water gas shift chemical looping (RWGS-CL) process.
Claims19
A catalyst composite comprising:
- a perovskite-oxide of formula ABO3, wherein A has a formula of LaxSry, and B is a transitional metal element, metal element, or a combination thereof;
- and
- an oxide support having a formula different from the perovskite-oxide;
- wherein x is 0-1, y is 0-1, and the sum of x and y is 1;
- and wherein the perovskite-oxide crystallite size is between 5 and 100 nm.
