Watching single protons moving at water-solid interfaces
The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount in a liquid determines whether the solution is acidic or basic. Pr ... more
Photoelectrochemical water-splitting efficiency hits 4.5%
Photoelectrochemical (PEC) water splitting for hydrogen fuel generation has been considered the Holy Grail of electrochemistry. But to achieve it, many scientists believe the materials have to be abundant and low cost.
The most promising oxide photocathodes are cuprous oxide (Cu2O) photoele ... more
Visualizing chemical reactions
Researchers at the joint EPFL-Empa lab in Sion have developed a reactor system and an analysis method that has allowed them to observe the real-time production of synthetic natural gas from CO2 and H2 for the first time.
Infrared (IR) thermography is used to determine the temperature of hu ... more
