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
A cheaper way to scale up atomic layer deposition
Atomic layer deposition (ALD) involves stacking layers of atoms on top of each other like pancakes. The atoms come from a vaporized material called a precursor. ALD is a well-established technique for manufacturing microelectronics like semiconductors and magnetic heads for sound recording, ... more
