In the quest for solutions to meeting future energy demands, solar fuels play an important role. A particularly promising example is photocatalysis since even incremental improvements in performance in this process are bound to translate into significant cost benefits. Here, we report that semiconducting and high surface area 3D silicon replicas prepared from abundantly available diatom fossils sustain photocurrents and enable solar energy conversion.
The fabrication and characterisation of a nano-structured photocathode using indium phosphide QDs and a bio-inspired Fe2S2(CO)6 catalyst sensitized on a p-type porous silicon electrode.
The conversion of titania (TiO2) nanotubes into titanium (Ti), while preserving their nanotubular structures is demonstrated for proposed application as bone implants and electrodes for combined local drug delivery and electrical stimulation therapy.
Hybrid systems combining molecular catalysts with inorganic materials is a promising solution towards cheap yet efficient and stable photoelectrochemical hydrogen production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
