我们报道了一种简单而通用的制备金属整体式催化剂的策略。我们的策略包括对FeCrAl纤维的表面进行热处理和喷洒纳米铂悬浮液。该催化剂具有较高的催化活性和良好的稳定性,在温和的温度下将挥发性有机物燃烧成CO2和H2O。催化剂的优异活性可以归因于热处理后在FeCrAl纤维表面形成的附着力良好的氧化铝涂层以及氧化铝涂层表面高度分散的铂纳米颗粒。
We report a facile and general strategy for the preparation of metallic monolithic catalysts. Our strategy involved subjecting the surfaces of FeCrAl fibers to thermal treatment and the spraying of Pt nanoparticles suspension liquid. The catalyst exhibited high catalytic activity and good stability in the combustion of volatile organic compounds to CO2 and H2O at mild temperature. The exceptional activity of the catalyst can be attributed to the well-adhered alumina coating that formed on the surfaces of the FeCrAl fibers after thermal treatment and the highly dispersed Pt nanoparticles on the surface of the alumina coating.
