Exploring the slow-light effect of Pt/TiO2-SiO2 inverse opal on photocatalytic nonoxidative coupling of methane

The slow-photon effect of Pt/TiO2-SiO2 inverse opal on photocatalytic nonoxidative coupling of methane was explored regarding the cavity size and filming treatment. The ethane production rate was maximized to 72 mu mol g(-1) h(-1) on a filmed microarray with a macroporous diameter of 170 nm, demonstrating the significance of enhancing light-matter interaction for methane conversion.
