Sulphated titania superacid (denoted as SO42−/TiO2) and sulphated zirconia-doped titania superacid (denoted as SO42−/ZrO2/TiO2) were prepared via a liquid-phase in-situ method. As-prepared SO42−/TiO2 and SO42−/ZrO2/TiO2 superacids were characterised by transmission electron microscopy, field emission scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectrometry. Moreover,...
