TL;DR: In this article, a thin layer of photodeposited amorphous Ni-oxyhydroxide (NiOOH) was applied on hematite (α-Fe2O3) photoanodes.

TL;DR: In this article, a 3D diagram of an electrochemical system as a function of pH and applied potential is presented for four catalysts, i.e., IrO2, Co3O4, Co 3O4 electrodeposited in a phosphate medium (Co-Pi) and Pt, allowing direct comparison of the activity of different electrode materials over a broad range of experimental conditions (pH, potential, current density).

TL;DR: In this paper, the oxidation states assumed by Ir in oxide systems used as heterogeneous catalysts for water oxidation are determined by means of in situ X-ray Absorption Spectroscopy (XAS).

TL;DR: The presence of bimetallic Pt-Au nanoparticles and of Ti³⁺ sites/O²⁻ vacancies in the bulk structure of titania are two key parameters to maximize light absorption and feedstock activation, finally resulting in good photocatalytic performances.

TL;DR: In this paper, the authors present a comprehensive study on low hydration Ir/IrO2 electrodes, made of an Ir core and an IrO2 shell, that are designed and synthesized with an innovative, green approach, in order to have a higher surface/bulk ratio of Ir active centers.
