Abstract
Lattice oxygen (LO)-mediated photothermal dry reforming of methane (DRM) presents a promising approach to syngas production. However, realizing high DRM efficiency and durability remains challenging due to the difficulty in activating LOs in catalysts. Herein, we demonstrate that partially substituting Fe sites in perovskite ferrite (LaFeO3) by Mn triggers LOs, bestowing the catalyst with superior activity and stability for photothermal DRM after modification with Ru. The Mn exchange induces a charge transfer from La to Mn, which combined with the incoming photoexcited electrons reconstructs the perovskite’s electronic structure, weakening the La–O–Mn bonds and facilitating the LO migration. Meanwhile,…
