🧪 Synthesizing solid catalysts is one thing, but for their application, they also need to undergo shaping or - in case of 🔌 #electrocatalysis - deposition on electrodes. Such steps are sometimes underrated in academic #catalysis research.

👉 Find out more on the strong effects of different binder additives on the wetting behavior of electrodes for #watersplitting in our recent collaborative work with the Particle Science and Technology Group of Doris Segets at @unidue.bsky.social.

Sub-5 nm Ru-based alloys have gained attention as promising electrochemical catalysts for water splitting. However, their synthesis has been constrained by thermodynamic immiscibility, which limits the development of a universally applicable preparation method.

In this study, the research team employed nanosecond laser ultrafast confined alloying (LUCA) to overcome the immiscible-to-miscible transition barrier…

Scientists develop sub-5 nm Ru-based alloy catalysts for efficient water splitting

A research team led by Prof. Liang Changhao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a novel method for synthesizing carbon nanotube (CNT)-supported intermetallic RuM (M = Cu, Rh, and Pd) alloys dominated by sub-5 nm nanoparticles (NPs). Their findings are published in Advanced Science.

Cheap, sustainable hydrogen through solar power: Withstanding high temperatures and the light of 160 suns, a new catalyst is 10 times more efficient than previous sun-powered water-splitting devices of its kind

A new kind of solar panel has achieved 9% efficiency in converting water into hydrogen and oxygen--mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.
