Synthesis and photochemistry of PT (IV) hydroxo complexes

Global energy consumption and the production of clean renewable energy have become greater challenges. Sunlight-induced splitting of water into H2 and O2 is one of the leading strategies to achieve clean and renewable energy. Transition metal photochemistry has considerable potential for making this task more viable. Along with water splitting, hydrohalic acid (HX) splitting is being thoroughly investigated. HX splitting is a more facile two electron process whereas water splitting is a relatively difficult four electron oxidation process. Light driven HX splitting and endergonic elimination of X2 (Br2 and Cl2) have received more attention as a potentially more economical and promising solar energy conversion process than water splitting. ...
