“…In order to guide the design of TiO 2 -based FLP for CH 4 activation, DFT calculations were rst carried out to screen out an ideal model through metal doping strategy. Metal ions (M) of Ga 3+ , Zn 2+ , In 3+ and Ti 3+ as typical p-type dopants which are prone to forming Lewis acid were adopted to construct FLP in TiO 2 [27][28][29][30][31][32] .…”
