a Mott-Schottky plot w.r.t. RHE at pH = 7 (at 1000 Hz, −1.5 to +1.5 V). b Band alignment based on Mott-Schottky plot (V vs RHE at pH = 7; valence band (VB) and conduction band (CB)). c Amount of H2 evolution under visible light and d corresponding TON (for H2) at 22 h. (Error bars in panels c and d represents the standard deviations of three catalytic runs). e Photocurrent measurement in 0.5 M Na2SO4 at +0.8 V, pH ~7 upon visible-light irradiation in the time interval of 30 sec. f Nyquist plot under light and dark condition. g TON (for H2) for Zn-TPY-TTF CPG under direct sunlight irradiation from 12th to 17th April 2019 (10:00 am to 4:00 pm) and the error bars represents the temperature range of photocatalytic set-up during catalysis under the sunlight irradiation. (Note: all visible-light experiments were performed under 300 W Xenon lamp using visible bandpass filter; 400–750 nm).
