Highly Efficient Production of H2 through Methanol Reforming

Production of hydrogen (H2) is an important task for clean energy. We designed a novel catalyst for efficient H2 production through methanol-water reforming. By tuning of the amount of Pt metal species and reducible Re oxide on the surface of reactive γ-Mo2N support, we have shifted the reaction from a competitive adsorption/activation model in typical supported metal catalysts to a non-competitive mechanism, synergistically resulting in enhanced catalytic turnover rates. We request 5 days on TOSCA to study the binding dynamics of methanol, water and intermediates over the exceptional catalyst (2Pt-2Re/γ-Mo2N). The proposed study will investigate the vibrational spectroscopy of the catalyst, adsorption of methanol and H2O molecules and any possible reaction intermediates on active sites. This study aims to reveal the role of Pt and ReOx sites in adsorption and activation of reactant molecules, giving key insights into the efficient H2 production.

氢气（H₂）的制备是清洁能源领域的一项重要课题。我们设计了一种新型催化剂，用于通过甲醇水重整工艺高效制备氢气（H₂）。通过调控反应性γ-氮化钼（γ-Mo₂N）载体表面的铂（Pt）金属物种与可还原铼（Re）氧化物的负载量，我们将典型负载型金属催化剂中的竞争吸附/活化反应模型转变为非竞争反应机制，协同提升了催化周转频率。我们申请在TOSCA装置上开展5天的实验，以研究该优异催化剂（2Pt-2Re/γ-Mo₂N）表面甲醇、水及反应中间体的结合动力学行为。本次拟开展的研究将对该催化剂的振动光谱、甲醇与水分子的吸附行为，以及活性位点上可能存在的各类反应中间体进行表征分析。本研究旨在阐明Pt与ReOₓ位点在反应物分子吸附与活化过程中的作用机制，为高效制备氢气（H₂）提供关键理论与实验依据。
