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

摘要

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 μmol 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.
