摘要

•Calcination temperature and fluorination treatment have impact on catalysts properties.•The NiF2-AlF3 catalyst calcined at 500 °C showed 20% yield of TrFE at 450 °C during 300 h.•The weak and medium (weak&medium) Lewis acid were the active site for the catalytic dehydrofluorination of CF3CH2F.
