From acidity to Australian Shiraz, oak to Oregon Pinot, Robinson delivers chapters of information and theory, intermingled with shaded "Practice" exercises, presented in a style as off-dry as one of the author's beloved Rieslings (the tannin in a lesser vintage Barolo is "like sucking on a matchstick").

Experimental results show that the incorporation of appropriate amounts of Al~2O~3 into SO~4^2^-/ZrO~2, SO~4^2^-/TiO~2 and SO~4^2^-/Fe~2O~3 is helpful for stabilizing the sulfur species and increasing the effective acid sites on the catalyst surfaces, which can improve the strong acidity and catalytic activity in benzoylation.

Microcalorimetric measurements of NH~3 adsorption on catalysts reveal that the remarkable strong acidity and catalytic activity of the Al- promoted catalysts are caused by a change of distribution of acid site strengths and an enhancement in the number of strong and intermediate-strong acid sites effective for the n-butane isomerization and benzoylation of toluene.

SO〓〓/M〓O〓 solid superacid was applied to the photocatalytic oxidation of organic pollutants for the first time. Porous SO〓〓/TiO〓 solid superacid catalysts with high specific surface area were prepared by sol-gel method. The photocatalytic degradation of bromomethane was used as model reaction. The influence of impregnation with H〓SO〓 solution on the structure of catalysts and their photocatalytic performance was systematically studied by using X-ray diffraction, X-ray photoelectron spectroscopy, N〓 sorption analysis applying BET method, UV-Vis diffuse reflectance spectroscopy, FTIR spectroscopy, O〓-TPD and photocatalytic activity measurement. The acidity of TiO〓-based catalysts was investigated by Hammett indicator method, NH〓-TPD and IR spectra of pyridine adsorbtion. The mechanism of superacidifing effects on photocatalytic performances such as the photocatalytic degradation rate of bromomethane, apparent kinetic constant and apparent quantum efficiency was discussed.The results indicated that SO〓〓 is combined with metal ions of TiO〓 in a chelating bidentate mode.

The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.
