Multimetallic particles could aid hydrogen economy, breaking down ammonia four times faster than ruthenium catalyst

A counterintuitive technique developed by researchers in the US and South Korea allows pentametallic nanoparticles of relatively uniform size and composition to form spontaneously from a precursor solution containing the five metals. The nanoparticles are a promising catalyst for the decomposition of ammonia into hydrogen and the technique could also potentially be extended to produce other multimetallic nanoparticles.
