This article also appears in: The photocatalytic overall water splitting ability of the as-prepared SrTiO 3-C950 is attributed to the surface oxygen vacancies that can make suitable energy levels for visible light response, improving the separation and transfer efficiency of photogenerated carriers. Water splitting to form hydrogen and oxygen using solar energy in the presence of semiconductor photocatalysts has long been studied as a potential means of clean, large-scale fuel production. In general, overall water splitting can be achieved when a photocatalyst is modified with a suitable cocatalyst. It is therefore important to develop both photocatalysts and cocatalysts. In the past five The photocatalytic water splitting performance was conducted by using pure water and UV-light irradiation, and photocatalytic H2 production was confirmed for both compounds. 2019-09-27 Photocatalytic water splitting with nanoporous gold .

Due to its high surface to volume ratio it is expected that solar radiation can be efficiently used for water splitting reaction at the surface. Photocatalytic overall water splitting (OWS) is a thermodynamically uphill process (Δ Hϕ = 285.5 KJ mol −1 ), which cannot occur spontaneously. It is composed of two half reactions, namely, the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), both of which are the processes of Gibbs free with. Photocatalytic water splitting reaction is a chemical process that involves direct solar energy conversion of H 2 O to H 2 and O 2 on heterogeneous photocatalysts.
