Fig. 6: Characterizations and photocatalytic H2 production activity of Pt@Zn-TPY-TTF CPG.

a, b HR-TEM images of Pt@Zn-TPY-TTF CPG. c Lattice fringes of the selected region. d Amount and TON (for H2) under visible-light irradiation and error bars represents the standard deviations of three catalytic runs. e TON (for H2) under direct sunlight irradiation from 27th June to 29th June 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.
