“…[125] When the compartments were illuminated by UV light, H 2 evolved on the Pt-loaded anatase TiO 2 in the Br 2 / Br À redox mediator solution in one compartment, while O 2 was produced on the rutile TiO 2 suspended in the Fe 3 + /Fe 2 + redox mediator solution in the other. Kitano et al [75] found that a TiO 2 /Ti/Pt thin film photocatalyst could be applied for the separate evolution of H 2 and O 2 from water in an H-type glass container, consisting of two water phases separated by a thin film and proton-exchange membrane. No redox mediator was used.…”

“…Recently, flamspray pyrolysis [138] and plasma oxidation pyrolysis [139] high-temperature treatment methods were used to prepare Fe-doped TiO 2 . The ion-beam technique, which was developed by Anpo et al, [61,75,[140][141][142] is an important and effective way to prepare cation-doped TiO 2 . The technique includes the metal-ion-implantation (MII) and radio-frequency magnetron sputtering (RF-MS) methods.…”

Hydrogen Production over Titania‐Based Photocatalysts

Because of their relatively high efficiency, high photostability, abundance, low cost, and nontoxic qualities, titania-based photocatalysts are still the most extensively studied materials for the photocatalytic production of hydrogen from water. The effects of the chemical and physical properties of titania, including crystal phase, crystallinity, particle size, and surface area, on its photoactivity towards hydrogen generation have been identified by various investigations. The high overpotential for hydrogen generation, rapid recombination of photogenerated electrons and holes, rapid reverse reaction of molecular hydrogen and oxygen, and inability to absorb visible light are considered the most important factors that restrict the photoactivity of titania, and strategies to overcome these barriers have been developed. These issues and strategies are carefully reviewed and summarized in this Minireview. We aim to provide a critical, up-to-date overview of the development of titania-based photocatalysts for hydrogen production, as well as a comprehensive background source and guide for future research.

“…Kitano et al [114] demonstrated a thin film device consisting of titania film and Ti-foil (50 µm) one side for oxygen evolution, and with platinum for hydrogen generation on the other side of an H-type photoreactor ( Figure 24). They used an aqueous solution of sulfuric acid (0.5 M) and sodium hydroxide (1 M) in the platinum and titania side, respectively.…”

Dye-Sensitized Photocatalytic Water Splitting and Sacrificial Hydrogen Generation: Current Status and Future Prospects

2017

View full text Add to dashboard Cite

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.

Ethanol and pentose were produced from lignocellulosic napiergrass by the simultaneous saccharification and fermentation process (SSF) using hydrolytic enzyme and S. Cerevisiae. After the ethanol was removed, the pentose solution was subjected to photocatalytic hydrogen evolution with Pt-loaded TiO 2 under UV-irradiation. This process converted 100 g of napiergrass into 12.3 g of ethanol and 1.76 g of hydrogen whose total combustion energy of (∆H) was 615 kJ. This was close to the ∆H (639 kJ) of the pentose (13.6 g) and hexose (27.4 g) obtained by the cellulose-saccharification of 100 g of napiergrass.
