Durability of SrTiO-TiO eutectic composite as a photoanode for photoelectrochemical water splitting.

The idea of employing sunlight - a virtually inexhaustible source of energy - to catalyze various chemical reactions or generate electrical current is intensively studied nowadays. Here, we describe a method for testing photoelectrochemical (PEC) stability developed using the example of photoanodes from an SrTiO-TiO eutectic composite. Eutectic composite stability measurements were carried out in long-term cycles: 0.
