In this episode, we’re diving into a fascinating breakthrough in clean engine technology! We’ll explore a recent Nature Communications study by Son Hoang and colleagues, where scientists created a powerful new catalyst using tiny, single platinum atoms anchored on titanium dioxide nanowire arrays. This clever design dramatically boosts the removal of pollutants like carbon monoxide and hydrocarbons from diesel exhaust—even at much lower temperatures—while using just a fraction of the platinum found in commercial catalysts. Plus, it stays strong and effective even under tough conditions. Tune in to hear how this innovation could help pave the way for cleaner, greener vehicles and smarter emission control.
