Ruthenium highlighted again in what could be another big boost for platinum group metals

Ruthenium, one of the six platinum-group metals (PGMs), is once again being given major research attention in view of it being exceptionally suited to uplifting the efficiency and sustainability of green hydrogen production from green ammonia. Late last year, it was a ruthenium-based catalyst that augmented the scarcity of iridium, another PGM, in the production of green hydrogen from water electrolysis.
