Plasmonic energy transformation in the photocatalytic oxidation of ammonium

• Plasmonic transformation to chemical energy demonstrated in ammonium oxidization
• Plasmonic heating effect boosts up the catalytic activity of platinum thin film.
• Endothermic chemical energy decreased in plasmonic photocatalytic reaction.

The plasmonic transformation of light into energy for a chemical reaction is demonstrated in the endothermic oxidation of ammonium ions. The plasmonic heating effect physically triggers a platinum thin film, which becomes an active catalyst for the plasmonic catalytic reaction. The amount of chemical energy consumed in the plasmonic photocatalytic reaction was less than that in the normal chemical process. A homogeneous, condensed, pinhole-less 8 nm platinum thin film fabricated via plasma-enhanced atomic layer deposition served as a medium that transformed the energy in two steps.
