Electrocatalyst decorated hematite nanowire arrays for photoelectrochemical water splitting

TiO2 and Fe2O3 films for photoelectrochemical water splitting.

Titanium oxide (TiO2) and iron oxide (α-Fe2O3) hematite films have potential applications as photoanodes in electrochemical water splitting. In the present work TiO2 and α-Fe2O3 thin films were prepared by two methods, e.g., sol-gel and High Power Impulse Magnetron Sputtering (HiPIMS) and judged on the basis of physical properties such as crystalline structure and surface topography and functio...

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...

Enhancing the Performance of Solar Water Disinfection with Potassium Persulfat: Laboratory Study with Enterococcus faecalis

Background & Aims of the Study: The safe drinking water providing is one of the most crucial objections in these centenaries. Bacterial water contamination and high rate of morbidity and mortality is crucial health threat. Efficiency of potassium persulfat (KPS) associated solar disinfection as a novel water disinfection technology was evaluated in batch scale experiments, us...

Branched TiO2 nanoarrays sensitized with CdS quantum dots for highly efficient photoelectrochemical water splitting.

This paper describes the design, characterization, and utilization of branched TiO2 nanoarrays sensitized with CdS quantum dots as anodes for photoelectrochemical water splitting. The remarkable photocurrent density (∼4 mA cm(-2) at a potential of 0 V versus Ag/AgCl) and high solar to hydrogen efficiency of the materials obtained were ascribed to the novel branched nanostructure and efficient e...
