Hydrofluorocarbons
-tetrafluoropropene (HFO-1234ze) using mesoporous nanoscopic aluminumfluoride-based catalysts [19]. The catalysts were prepared via a sol–gel process in the presence of polyols, allowing for the evolution of a large surface area and improved acidic properties when compared to fluorinated Cr2O3 or traditional β-AlF3
investigated [16][28][32][33][34][35][36][37][38][39]. Especially microporous aluminum chlorofluoride (ACF, AlClxF3−x; x = 0.05–0.3), which has a large surface area (>200 m2g−1) and was patented by Dupont in 1992, has been extensively studied [40][41][42][43][44][45][46]. It is an amorphous aluminumfluoride
