Some Like It Hot: Geoffry A. Ozin and co‐workers demonstrate that the reverse water gas shift (RWGS) reaction, driven by a visible and near infrared responsive Pd@Nb 2 O 5 is thermally activated with measured conversion rates as high as 1.8 mmol gcat −1 h −1 , in article 1600189. Specifically, the RWGS reaction is enabled by heat generated from thermalization of photoexcited charge carriers in the Pd nanocrystals that function as “nanoheaters” for the entire Pd@Nb 2 O 5 assembly, through non‐radiative relaxation of inter‐band and intra‐band conduction electron transitions. Overall this study advances our understanding of the underlying mechanism of photothermally driven CO 2 reduction. Cover illustration by Chenxi Qian.
