Here, we show that metal oxide surfaces catalyze the formation of intermediate defluorinated tetrafluoroethylene (TFE) radicals, resulting in enhanced binding on the corresponding metal oxide surfaces. We attribute the preferential adsorption and radical formation of TFE on CrO(0001) relative to TiO(110) to the low oxygen coordination of Cr surface atoms. This hints at a possible dependence of the TFE binding strength to the surface stoichiometry of metal-oxide surfaces.
在这里，我们表明金属氧化物表面催化中间脱氟四氟乙烯（TFE）自由基的形成，从而增强在相应金属氧化物表面上的结合。我们将TFE在CrO(0001)上相对于TiO(110)的优先吸附和自由基形成归因于Cr表面原子的低氧配位。这暗示了TFE结合强度可能依赖于金属氧化物表面的化学计量。
