Abstract
Exemplary oxygen carrier particles may comprise a mesoporous support and a plurality of metal oxide-based nanoparticles immobilized on the mesoporous support. The plurality of metal oxide-based nanoparticles may comprise 10 volume percent to 80 volume percent of mesopores in the mesoporous support. A reactor may comprise a feedstock inlet in fluid communication with a carbonaceous feedstock source, a product stream outlet, and oxygen carrier particles. Exemplary reactors may be operated by providing a carbonaceous feedstock to an inlet of the reactor, providing oxygen carrier particles within the reactor, and collecting a product stream from an outlet of the reactor.
