Photothermal catalytic performance of the nanostructured Pd@Nb₂O₅ samples. a) CO production rates over Pd@Nb₂O₅ in the dark at room temperature (RT), under irradiation from a 300 W Xe lamp, and in the dark at a reaction temperature of 160 °C. b) Spectral irradiance incident onto the Pd@Nb₂O₅ catalyst with different cut‐off filters for batch reaction tests A through F. c) Spectral irradiance incident onto the Pd@Nb₂O₅ catalyst for batch reactions I through V. d) The RWGS reaction rates plotted as a function of absorbed power for the series of batch reactions A–F (red line) and I–V (black line).
