Phys.org October 21, 2024 One of the biggest challenges in electrochemical water splitting is oxygen evolution reaction (OER), a sluggish reaction in which water molecules are broken down into oxygen and hydrogen. The OER can be accelerated by using noble metal catalysts; however, these metals are expensive and scarce, and speeding up the reaction requires additional energy. An international team of researchers (USA – Perdue University, China, Taiwan, Germany) has developed a new method using iridium coordinated with dimethylimidazole (MI) as a reaction accelerator for electrochemical splitting of water which accelerated the production of hydrogen and made it more sustainable.

The powerhouse of the future: Artificial cells
Phys.org March 28, 2023 Sustainable energy conversion modules are the main challenges for building complex reaction cascades in artificial cells. Recent advances in biotechnology have enabled this sustainable energy supply, especially the adenosine triphosphate (ATP), by mimicking the organelles, which are the core structures for energy conversion in living cells. Three components are mainly shared by the artificial organelles: the membrane compartment separating the inner and outer parts, membrane proteins for proton translocation, and the molecular rotary machine for ATP synthesis. Depending on the initiation factors, they are further categorized into artificial mitochondrion and artificial chloroplasts, which use chemical nutrients […]
