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.

Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel—just as plants do—researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. —Johanna Eichhorn.

UNSW Sydney team develops inexpensive water-splitting catalyst using 2D MOF framework array

Green Car Congress

UNSW Sydney chemists have fabricated a new, inexpensive catalyst for water splitting based on an ultrathin nanosheet array of metal-organic frameworks (MOFs) on different substrates. Unexpectedly, the integrated MOF electrodes demonstrate superior performances towards OER, HER and overall water splitting. —Duan et al.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Natural gas or coal is used as the energy source of the ammonia industry. is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature. To the best of our knowledge, there is no report on artificial synthesis of ammonia direct from air and water.
