Hot electron photochemistry has made strong claims for improved control or chemical reactions. Here we discuss these claims in the light of a plethora of model experiments and theories, asking what are the key issues to solve. I particularly highlight the need to understand nanoscale thermal hot-spots, thermal gradients, and thermal transport, as well as the conventional optical confinement in plasmonics. I note how the ‘direct electron transfer’ process seems to dominate, and resembles well known ‘indirect excitons’ in semiconductor quantum wells. I believe a crucial advance still required is a prototype nano-confined geometry which allows reactants and products to access a well-controlled metallic atomic surface.
