Abstract

We developed a composite consisting of mesoporous ZrO₂ thin films supporting catalytically active gold nanoparticles (Au NPs) for the oxidative removal of carbon monoxide (CO). At first, highly ordered mesoporous ZrO₂ (m-ZrO₂) thin films are prepared by sol-gel-based spin-coating process followed by a controlled thermal treatment process in air. Then, Au NPs are successfully dispersed and deposited over the entire framework of mesoporous ZrO₂ thin films to form Au/m-ZrO₂ films. The specific surface area and crystallinity of the m-ZrO₂ thin films as well as the periodicity of the mesoporous framework can be controlled by adjusting the calcination temperature and the synthetic parameters. The catalytic efficiency of the optimized Au/m-ZrO₂ composite film toward CO conversion reaches 94% of circulation time, and is well-retained even after 1 h (∼88%).
