Photoelectrochemical activity of as-grown, α-Fe2O3 nanowire array electrodes for water splitting.

High-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode towards photoelectrochemical water splitting.

Many narrow band-gap semiconductors cannot fulfil the energetic requirements for water splitting, thus the assistance of large external voltages to complete the water decomposition reaction is required. Through thermal decomposition of Fe(NO3)3 on n-Si nanowires prepared by the chemical etching method, we fabricated a high-performance n-Si/α-Fe2O3 core/shell nanowire array photoanode that exhib...

Electrochemical synthesis of p-type Zn-doped α-Fe2O3 nanotube arrays for photoelectrochemical water splitting.

A facile electrochemical method is developed to synthesize p-type Zn-doped α-Fe2O3 nanotube arrays that demonstrate excellent photoelectrochemical properties for water splitting.

Surface Engineered Doping of Hematite Nanorod Arrays for Improved Photoelectrochemical Water Splitting

Given the narrow band gap enabling excellent optical absorption, increased charge carrier density and accelerated surface oxidation reaction kinetics become the key points for improved photoelectrochemical performances for water splitting over hematite (α-Fe2O3) photoanodes. In this study, a facile and inexpensive method was demonstrated to develop core/shell structured α-Fe2O3 nanorod arrays. ...

Solution growth of Ta-doped hematite nanorods for efficient photoelectrochemical water splitting: a tradeoff between electronic structure and nanostructure evolution.

Ta-doped hematite (α-Fe2O3) nanorod array films were successfully prepared on fluorine-doped tin dioxide (FTO) coated glass substrates via a facile solution growth process with TaCl5 as a Ta doping precursor. Under 1 sun illumination and at an applied potential of 1.0 V vs. Ag/AgCl, the Ta-doped α-Fe2O3 photoanode with optimized dopant concentration showed a photocurrent density as high as 0.53...
