摘要：

Herein it is shown that hydrotalcite-like compounds (HTlcs), doped with a suitably reactive metal, can efficiently act as water oxidation catalysts. As a case study, a ternary HTlc of formula [Zn0.667Al0.306Ir0.027(OH)(2)]Cl(0.333)0.6H(2)O, in which iridium is homogeneously distributed into the octahedral sites of brucite-type sheets, was prepared and tested as a heterogeneous water oxidation catalyst, using NaIO4 as a sacrificial oxidant. This HTlc showed excellent performance in terms of turnover frequency (up to 113min(-1)), turnover number (>11900), stability and recyclability.
