Core/Shell/Shell Nanowire Photocathodes for Neutral pH Water Splitting
Silicon is the most widely used semiconductor for solar cells [ 1–4 ] and has also shown promising performances in photoelectrochemical (PEC) cells for hydrogen production. [ 5–10 ] Silicon photoelectrodes with nano/micro structures such as nano/ micro wire array [ 9,11 ] and black silicon [ 7 ] have exhibited improved PEC performances. Silicon nanowire (NW) arrays, in particular, are of consid...
متن کاملNiO(x)-Fe2O3-coated p-Si photocathodes for enhanced solar water splitting in neutral pH water.
We report successful growth of a uniform and scalable nanocomposite film of Fe2O3 nanorods (NRs) and NiOx nanoparticles (NPs), their properties and application for enhanced solar water reduction in neutral pH water on the surface of p-Si photocathodes.
متن کاملPhotoelectrochemical water splitting: silicon photocathodes for hydrogen evolution
The development of low cost, scalable, renewable energy technologies is one of today’s most pressing scientific challenges. We report on progress towards the development of a photoelectrochemical water-splitting system that will use sunlight and water as the inputs to produce renewable hydrogen with oxygen as a by-product. This system is based on the design principle of incorporating two separa...

متن کاملRegulating proton-coupled electron transfer for efficient water splitting by manganese oxides at neutral pH
Manganese oxides have been extensively investigated as model systems for the oxygen-evolving complex of photosystem II. However, most bioinspired catalysts are inefficient at neutral pH and functional similarity to the oxygen-evolving complex has been rarely achieved with manganese. Here we report the regulation of proton-coupled electron transfer involved in water oxidation by manganese oxides...
