Abstract
In this study, LaBO3 (B = Co, Fe, Cu, Al) perovskite catalysts were introduced for Methanol Steam Reforming (MSR). Results showed that LaCoO3 displayed a 100 % methanol conversion efficiency and a notable hydrogen production rate of 7.86 mol/min/gcat, maintaining stability for more than 40 h at 600 °C. Theoretical computations indicate that the CH3O dehydrogenation to CH2O (a rate-determining process) occurs without methanol breaking down into methane and coke, thus ensuring its long-lasting stability. The fusion of experimental findings with theoretical forecasts underscores the prowess of LaCoO3 as a remarkable perovskite catalyst and its extensive possibilities in the realm of methanol hydrogen generation.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
