Response to Comment on "Quantifying hot carrier and thermal contributions in plasmonic photocatalysis".

Sivan et al claim that the methods used to distinguish thermal from hot carrier effects in our recent report are inaccurate and that our data can be explained by a purely thermal mechanism with a fixed activation energy. This conclusion is invalid, because they substantially misinterpret the emissivity of the photocatalyst and assume a linear intensity-dependent temperature in their model that is unrealistic.
