Electronic structure regulation of halogen anion-intercalated MgAl-LDH for highly selective photothermal oxidation of CH4

The photothermal catalytic oxidation of CH 4 was performed on a series of halogen anion-intercalated MgAl-LDHs. MgAl-F exhibited 86.5% selectivity for CO and completely inhibited the production of CO 2 , arising from the strong interaction of F − with OH on the host layer.
