“…The use of twin reactor minimized the deactivation of Pt/SrTiO 3 :Rh photocatalyst and the modified Nafion membrane in the twin reactor did not obstruct the water splitting reaction. A similar twin reactor was designed by Lo et al [113] for the photocatalytic water splitting under visible light. Pt/SrTiO3:Rh and WO3 were used for hydrogen generation and oxygen generation, respectively.…”

Today, global warming and green energy are important topics of discussion for every intellectual gathering all over the world. The only sustainable solution to these problems is the use of solar energy and storing it as hydrogen fuel. Photocatalytic and photo-electrochemical water splitting and sacrificial hydrogen generation show a promise for future energy generation from renewable water and sunlight. This article mainly reviews the current research progress on photocatalytic and photo-electrochemical systems focusing on dye-sensitized overall water splitting and sacrificial hydrogen generation. An overview of significant parameters including dyes, sacrificial agents, modified photocatalysts and co-catalysts are provided. Also, the significance of statistical analysis as an effective tool for a systematic investigation of the effects of different factors and their interactions are explained. Finally, different photocatalytic reactor configurations that are currently in use for water splitting application in laboratory and large scale are discussed.

The final publication is available at Springer via http://dx.doi.org/10.1007/698_2014_261 AbstractThe use of photocatalysis for the photosplitting of water to generate hydrogen and oxygen has gained interest as a method for the conversion and storage of solar energy. The application of photocatalysis through catalyst engineering, mechanistic studies and photoreactor development has highlighted the potential of this technology, with the number of publications significantly increasing in the past few decades. In 1972 Fujishima and Honda described a photoelectrochemcial system capable of generating H 2 and O 2 using thin film TiO 2 . Since this publication, a diverse range of catalysts and platforms have been deployed, along with a varying range of photoreactors coupled with photoelectrochemical and photovoltaic technology. This chapter aims to provide a comprehensive overview of photocatalytic technology applied to overall H 2 O splitting. An insight into the electronic and geometric structure of catalysts is given based upon the one and two step photocatalyst systems.One step photocatalysts are discussed based upon their d 0 and d 10 electron configuration and core metal ion including transition metal oxides, typical metal oxides and metal nitrides. The two step approach, referred to as the Z-scheme, is discussed as an alternative approach to the traditional one step mechanism and the potential of the system utilise visible and solar irradiation. In addition to this the mechanistic procedure of H 2 O splitting is reviewed to provide the reader with a detailed understanding of the process. Finally, the development of photoreactors and reactor properties are discussed with a view towards the photoelectrochemical splitting of H 2 O.

“…Numerous experimental demonstrations pertinent to particle-suspension, Zscheme reactors with electron transfer mediated by a soluble redox shuttle have been reported [40][41][42][43][44][45][46][47][48][49][50], and a comprehensive review on this topic has been presented by Fabian and colleagues [20]. The predominant focus in the aforementioned studies was the identification of semiconductor materials [40][41][42][43][44][45][46][47][48] with enhanced activities for implementing the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER), development of surface treatment techniques and selection of redox shuttles to suppress undesired interfacial electron-transfer reactions [41,49], and evaluation of the effectiveness of cocatalyst [50] and coating materials [51].…”
