Palladium oxide nanoparticles were loaded onto a nanostructured MnO2 aerogel by a deposition–precipitation method. The resulting nanomaterial exhibited excellent catalytic activity for low-temperature methane combustion, achieving complete methane conversion to CO2 at 330 °C (GHSV = 180000 mL/(g h)). The enhanced activity is attributed to excellent reducibility and exposure of active PdO facets. The hydrothermal stability of the composite catalyst was improved, and the deactivation mechanism was explored. These novel catalysts form free-standing monoliths and could be useful in natural gas vehicles and other methane scrubbing applications.

MnO 2纳米线气凝胶上负载的PdO纳米颗粒作为低温甲烷燃烧的催化剂
通过沉积-沉淀法将氧化钯纳米颗粒加载到纳米结构的MnO 2气凝胶上。所得纳米材料对低温甲烷燃烧表现出优异的催化活性，在330°C（GHSV = 180000 mL /（gh））时，甲烷完全转化为CO 2。增强的活性归因于极好的还原性和活性PdO面的暴露。改善了复合催化剂的水热稳定性，探讨了失活机理。这些新型催化剂形成独立的整体，可用于天然气运输工具和其他甲烷洗涤应用。
