Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. Alongside hydrogen generation from water, the multi-disciplinary research team is investigating photochemical conversion of carbon dioxide into synthetic fuel.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential.

PNNL team develops carbon nanotube-silicon microspheres as high-performance Li-ion anodes

Green Car Congress

Although nanostructured Si can mitigate that structure failure, nanomaterials, with their high surface area and low tap density, can be detrimental for both their electrochemical performance and practical manufacturing. The composite electrodes of carbon-nanotube@silicon@carbon-graphite with a practical loading (3?
