Abstract
Described herein is a supported catalyst for a liquid-phase reaction, the supported catalyst comprising a perovskite support comprising A-site species and B-site species and a catalytic component on a surface of the perovskite support. Also described herein is a method for tuning the selectivity of a supported catalyst.
Claims24
A method for making a desired reaction product under liquid-phase conditions, the method comprising:
- providing a supported catalyst having selectivity for the desired reaction product, the supported catalyst comprising:
- a perovskite support comprising an A-site species and a B-site species;
- and
- metal or metal alloy catalytic particles on a surface of the perovskite support, wherein the B-site species is selected to provide selectivity for the desired reaction product;
- and
- contacting reactants with the supported catalyst to provide the desired reaction product.
A process for tuning the selectivity of a supported catalyst comprising a perovskite support comprising an A-site species and a B-site species, and metal or metal alloy catalytic particles deposited on the perovskite support, the process comprising varying the B-site species of the perovskite support to tune the selectivity of the supported catalyst.
A process for identifying a supported catalyst having selectivity for a desired reaction product, the process comprising:
- (a) selecting a reaction for producing the desired reaction product;
- (b) selecting a metal or metal alloy for catalysing the selected reaction;
- (c) providing a plurality of supported catalysts, each supported catalyst comprising:
- a perovskite support comprising an A-site species and a B-site species;
- and
- catalytic particles of the selected metal or metal alloy on a surface of the perovskite support,
- each of the supported catalysts having a different B-site species;
- (d) carrying out the selected reaction using each of the supported catalysts provided in step (c);
- and
- (e) determining the selectivity of each of the supported catalysts provided in step (c) for the desired reaction product.
A method of forming a supported catalyst for a liquid-phase reaction, the method comprising:
- providing a perovskite support comprising an A-site species and a B-site species, wherein the B-site species is selected to control the selectivity of the supported catalyst towards a desired reaction product;
- depositing metal or metal alloy catalytic particles on a surface of the perovskite support;
- and
- exposing the supported catalyst to a temperature not greater than about 350° C. such that the metal or metal alloy catalytic particles remain on the surface of the perovskite support.
A perovskite supported catalyst for a liquid-phase reaction, the supported catalyst comprising:
- a perovskite support comprising an A-site species and a B-site species;
- and
- metal or metal alloy catalytic particles on a surface of the perovskite support.
