The recently published points of zero charge (PZC) of various materials are compiled to update previous compilations [M. Kosmulski, Chemical Properties of Material Surfaces, Dekker, New York, 2001; M. Kosmulski, J. Colloid Interface Sci. 253 (2002) 77; M. Kosmulski, J. Colloid Interface Sci. 275 (2004) 214]. The recent results corroborate the previously found PZC with a few exceptions. The PZC of alumina obtained from the second-harmonic generation response is substantially lower than the PZC obtained by means of standard methods, while for titania the difference is less significant. PZC of Tl2O3 at pH 7.9 was reported for the first time. A surprisingly insignificant temperature effect on the IEP of rutile was found. Recent model studies aimed at explanation of the effect of the nature of 1-1 electrolytes on the course of charging curves and of discrepancies in the PZC of different materials having the same chemical formula are summarized.
近期发表的各种材料的零电荷点（PZC）被汇总起来，以更新之前的汇总结果[M. 科斯穆尔斯基，《材料表面的化学性质》，德克尔出版社，纽约，2001年；M. 科斯穆尔斯基，《胶体与界面科学杂志》253 (2002) 77；M. 科斯穆尔斯基，《胶体与界面科学杂志》275 (2004) 214]。近期的结果证实了之前发现的PZC，但有一些例外情况。通过二次谐波产生响应得到的氧化铝的PZC显著低于通过标准方法得到的PZC，而对于二氧化钛，差异则不太显著。首次报道了在pH 7.9时Tl2O3的PZC。发现金红石的等电点（IEP）受温度的影响出人意料地小。总结了近期旨在解释1-1电解质性质对充电曲线过程的影响以及具有相同化学式的不同材料在PZC方面差异的模型研究。
