PdO Nanoparticles Supported on MnO2 Nanowire Aerogels as Catalysts for Low-Temperature Methane Combustion
Source abstract
Abstract
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.
