Microwave-Driven Reduction Accelerates Oxygen Exchange in Perovskite Oxides.

ABSTRACT: Microwave-assisted oxide reduction has emerged as a promising method to electrify chemical looping processes for renewable hydrogen production. Moreover, these thermochemical cycles can be used for thermochemical air separation, electrifying the O₂ generation by applying microwaves in the reduction step. This approach offers an alternative to conventional cryogenic air separation, producing pure streams of O₂ and N₂. The electrification by microwaves lowers the requirements for titanate perovskites (CaTi_1-xMn_xO_3-δ), which typically demand high temperatures for thermochemical cycles. Microwave activation allows for a drastic reduction in the operation conditions of the reduction reaction, leading to unprecedente
