Researchers have discovered a catalyst of precious metals that is uncovering some real treasure in a biodiesel by-product. Rice University says engineers at the school have found palladium-gold nanoparticles, used as catalysts for cleaning polluted water, are also surprisingly good at turning glycerol into valuable chemicals.

Through dozens of studies, [Michael] Wong’s team focused on using the tiny metallic specks to break down carcinogenic and toxic compounds. But his latest study, which is available online and due for publication in an upcoming issue of the Royal Society of Chemistry’s journal Chemical Science, examined whether palladium-gold nanocatalysts could convert glycerol, a waste byproduct of biodiesel production, into high-value chemicals.
