The quest for hydrogen as a clean and sustainable energy source has gained momentum. To produce green hydrogen, water must be split into oxygen and hydrogen. This water splitting process is facilitated by electrocatalysts that enhance the chemical reaction rate.
and thus to a carbon-free economy. A team of researchers led by the Max-Planck-Institut für Eisenforschung has discovered why these catalysts actually deteriorate and suffer from a shorter life expectancy.
"Our findings revealed that impurities do get introduced during synthesis. Surprisingly, we discovered that boron impurities could enhance the catalyst's performance by expanding its lattice structure. However, we observed that thedecreases after a certain amount of hydrogen is produced and wanted to understand why this happens to find ways to maintain the performance," explains Prof.

Examining the entrainment rate of shallow cumulus clouds and its influencing factorsClouds are not only a mesmerizing spectacle in the sky but also a crucial player in Earth's atmospheric dynamics. Among the many types of clouds, cumulus clouds stand out because of their pivotal role in regulating weather patterns and climate. One of the fundamental processes that shape the development of cumulus clouds is entrainment mixing, where surrounding air interacts with the cloud, influencing its growth and properties.
