The reduction of CO2 to renewable fuels must be coupled a sustainable oxidation process devise viable device that produces solar fuels. In photoelectrochemical cells, water O2 is the predominant reaction and typically requires pair light absorbers or an applied bias voltage when reduction. Here, we report bias-free for simultaneous formate alcohol aldehyde in aqueous conditions. photoanode cons...

In an unprecedented approach, simultaneous photoelectrochemical and IR-spectroscopic measurements were performed to study photoinduced charge separation processes on nanostructured rutile thin films.

Novel carbon nitride polymer sensitized TiO(2) nanotube arrays with high photocatalytic activity and photoelectrochemical response under visible light irradiation are prepared by electrodeposition.

A photoelectrochemical sensing strategy for highly sensitive detection of small molecules was developed based on the recognition interaction between aptamer and target molecule-ATP.

In this chapter, the physical properties of group III-nitride compound semiconductors are reviewed in the context to act as semiconducting material in photoelectrocatalytic solar fuel structures. The band alignments in the InN-GaN-AlN-InN alloy system are summarized and discuss with respect to potential catalysts HOMO and LUMO states, providing efficient charge transfer in photoelectrochemical ...

Bridged ZnO nanorod arrays on V-grooved Si(100) substrate were used as the photoanode of a photoelectrochemical (PEC) cell for water splitting. Photolithography followed by reactive ion etching was employed to create a V-grooved structure on a Si substrate. ZnO nanorod arrays were grown via a hydrothermal method. The light trapping and PEC properties are greatly enhanced using the bridged ZnO n...

Dye-sensitized solar cell, known as an emergent technology, has been attracted attention around the world. It easily produced by a mesoporous semiconductor oxide (SO), with dye. On other hand, some unexpected reactions back-electron recombination, reducing cell efficiency. The presence of molecules to act passivation might rise up collection reaction rate, and enhance photoelectrochemical syste...

n-Type Si has been shown to serve as a stable photoanode in a cell for the conversion of light to electricity. The other components of the cell are a Pt cathode and an electrolyte consisting of an ethanol solution of [n-Bu(4)N]ClO(4) with a redox couple of ferricenium/ferrocene. Data from a two-compartment cell show that ferrocene is oxidized to ferricenium with 100 +/- 2% current efficiency at...
