Pyro-electrolytic water splitting for hydrogen generation

Investigation of Iron Oxide Morphology in a Cyclic Redox Water Splitting Process for Hydrogen Generation

A solar fuels generation research program is focused on hydrogen production by means of reactive metal water splitting in a cyclic iron-based redox process. Iron-based oxides are explored as an intermediary reactive material to dissociate water molecules at significantly reduced thermal energies. With a goal of studying the resulting oxide chemistry and morphology, chemical assistance via CO is...

Water Splitting Technologies for Hydrogen Cogeneration from Nuclear Energy

Photoelectrochemical 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...

Analysis of Solar Thermochemical Water-Splitting Cycles for Hydrogen Production

Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...

Photocatalytic generation of hydrogen by core-shell WO3/BiVO4 nanorods with ultimate water splitting efficiency

Efficient photocatalytic water splitting requires effective generation, separation and transfer of photo-induced charge carriers that can hardly be achieved simultaneously in a single material. Here we show that the effectiveness of each process can be separately maximized in a nanostructured heterojunction with extremely thin absorber layer. We demonstrate this concept on WO3/BiVO4+CoPi core-s...
