The dimerization of PNTP to DMAB is possibly driven directly by the laser heating effect. In plasmonic photocatalysis, the conversion rate and reaction rate are highly dependent on the size of the gold nanoparticles. The reaction is not only driven by hot electron transfer, but also to a large extent by photothermal conversion. This extraordinary evidence sheds new light on the puzzle of plasmonic photochemical reactions.
