A generalized approach for enhancing contact-electro-catalysis of oxides in a broad temperature range by fluorination.

ABSTRACT: Contact-electro-catalysis (CEC) has emerged as a sustainable and effective strategy for promoting chemical reactions. While polymers are the mostly used CEC catalysts, their limited contact-electrification (CE) performance at high temperatures limits the application of CEC in some environment. Here, we engineer fluorinated functional groups onto a series of oxides (SiO₂ Al₂O₃, ZrO₂ and MgO) for enhancing their CE abilities. The fluorinated SiO₂ (F-SiO₂), for example, exhibits comparable CEC efficiency to that of polymers at room temperatures, and, more importantly, superior performance at elevated temperatures up to 180 °C. This should be mainly ascribed to the thermal stability of F-SiO₂ and the facilitated elect
