In article number 1701913, Ferdi Karadas, Ömer Dag, and co-workers synthesize transparent mesoporous thin films of LiCoO₂ and LiMn₂O₄ by employing a molten salt assisted self-assembly method. A clear solution of the ingredients is coated over a subtrate that is heated at elevated temperatures to obtain the transparent mesoporous metal lithiates. The mesoporous LiCoO₂ film electrode, coated over a FTO substrate, demonstrates promising water oxidation electrocatalysis at low overpotentials.
