Photocatalytic and photoelectrochemical (PEC) water splitting using semiconductor materials has attracted considerable interest due to its potential to cleanly produce H 2 from water by utilizing abundant solar light. Since Fujishima and Honda used a TiO 2 photoanode in 1972 to split water, researchers have been attempting to develop water-splitting systems that can efficiently use visible

In principle this process can pro Main article: Photocatalytic water splitting Research is being conducted over photocatalysis , [19] [20] the acceleration of a photoreaction in the presence of a catalyst. Its comprehension has been made possible ever since the discovery of water electrolysis by means of the titanium dioxide. Photocatalytic water splitting is an artiﬁcial photosynthesis process that uses photocatalysis in a photoelectrochemical cell to initiate the light-driven splitting of water into its elemental constituents, H 2and O 2 1−3Theoretically, only sunlight, water, and a photocatalyst are required for water splitting reactions.

Visible-Light-Driven Photocatalytic Water Splitting: Recent Progress and Challenges Lihua Lin,1 Takashi Hisatomi,1 Shanshan Chen,1 Tsuyoshi Takata,1 and Kazunari Domen1,2,* Sunlight-driven photocatalytic water splitting is one of the most promising ap-proaches to generating renewable hydrogen as an energy source. In recent

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.

Sacriﬁcial reagents are Water splitting holds particular promise since it utilizes water, an inexpensive renewable resource. Photocatalytic water splitting has the simplicity of using a 1 Photoelectrochemical Water Splitting as a Pathway to Sustainable Energy. 2 Brief History of Nanoscale Water Splitting Photocatalysis. 3 Size Dependency of Shortly after the discovery of photoelectrochemical cells, it was also shown that water could be split into hydrogen and oxygen using self-supported photocatalysts Overall water splitting, evolving hydrogen and oxygen in a 2:1 stoichiometric ratio , using particulate photocatalysts is a potential means of achieving scalable Using sunlight to split water is attractive for renewable hydrogen production, but challenging to carry out efficiently.

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. Upon absorbing photons, the photocatalyst would generate electron-hole pairs whereby the electrons would reduce the H+ ions to H 2 and the holes would oxidize H 2 O to O 2

water oxidation, whereas the co-catalyst reduces protons. Charges are separated at the materials interface. E CB , conduction band energy level; E VB , valence band energy level. (b) Design for photocatalytic water splitting reactor. A polymer pipe is used to hold the photocatalyst suspension and to separate the H 2 and O 2 gas mixture by allowing One of the challenging issues in photocatalytic overall water splitting is to efficiently separate the photogenerated charges and the reduction and oxidation catalytic sites on semiconductor-based photocatalysts. Photocatalytic water splitting is an artificial photosynthesis process with photocatalysis in a photoelectrochemical cell used for the dissociation of water into its constituent parts, hydrogen (H 2 ) and oxygen ( O 2017-08-08 · of photocatalytic water splitting into hydrogen and oxygen by using light from the solar spectrum, which is one of the most investigated photosynthetic reactions. Photocatalytic water splitting using solar energy is considered to be artiﬁcial photosynthesis that produces a solar fuel because the reaction Photocatalytic water splitting using solar energy is considered to be artificial photosynthesis that produces a solar fuel because the reaction mimics nature’s photosynthesis not only in its redox reaction type but also in its thermodynamics (water splitting: 1.23 eV vs glucose formation: 1.24 eV).
