The development of new routes towards the generation of environmentally friendly solar fuels, such as molecular hydrogen (H2) for use in fuel cells, is a grand challenge facing the scientific community. In this regard, water splitting represents one of the ...
The direct transformation of sunlight into fuels and chemicals has attracted considerable attention for the potential impact on the storage of solar energies at large scales and the reduction of CO2 emissions. More than 80% of our current global energy con ...
This article presents an overview of our research in the field of colloidal nanocrystal synthesis and their implementation into water splitting and CO2 reduction electrochemical cells. We discuss our approaches to tailormade novel material platforms to adv ...
Concurrent solar generation of hydrogen and CO through photoelectrochemical (PEC) water and CO2 electrolysis, and the subsequent use of the product gas mixture in conventional Fischer-Tropsch processes, has the potential to provide a flexible pathway for d ...
We present a facile nonpolar organic solution synthesis and processing method for water splitting photoanodes based on iron oxide with a relatively low sintering temperature (550 degrees C). The photocurrent of these photoanodes can reach 3.3 mA cm(-2) at ...
A homologous Ni-Co based nanowire catalyst pair, composed of NixCo3-xO4 nanowires and NiCo/NiCoOx nanohybrid, is developed for efficient overall water splitting. NixCo3-xO4 nanowires are found as a highly active oxygen evolution reaction (OER) catalyst, an ...
A device having a water vapor microelectrolyzer cell including microstructured parallel electrodes where the water splitting reactions can take place, the microstructured electrodes being covered by a thin layer of solid-state ion conducting material to al ...
A combined experimental-numerical approach was used to study transient phenomena occurring in a photoelectrochemical cell using a membrane-separated porous TiO2-based photoanode and a dark Pt-based cathode. The effects of three parameters (pH in the anodic ...
Monolithic solar water splitting devices consist of photovoltaic materials integrated with electrocatalysts and produce solar hydrogen by water splitting upon solar illumination in one device. Upscaling of monolithic solar water splitting devices is obstru ...
Motivated to revolutionize our today's fossil fuels based energy production, my work concentrated on the investigation of promising low-cost materials for photoelectrochemical hydrogen production and photovoltaic electricity generation. Hydrogen presents a ...
