Abstract

A promising fluorinated NiO/Al₂O₃ catalyst for synthesizing trifluoroethylene through the catalytic dehydrofluorination of CF₃CFH₂ was prepared, and the relationship between the Lewis acid sites and activity was investigated. 20.1% conversion of CF₃CFH₂ was observed, and the selectivity to trifluoroethylene was observed to be 99% at 430 °C after 100 h.
