(a) UV-vis absorption spectra of the CN and D-CN samples. (b) Stability test of 3.0 wt% Pt-deposited D-CN (50 mg) for H₂ production in aqueous triethanolamine solution (10 vol%) under visible light and CN sample is also shown for comparison. (c) Transient photocurrent generation from CN and D-CN electrodes at 0.6 V versus Ag/AgCl in 0.2 M Na₂SO₄ under simulated sunlight irradiation. (d) EIS Nyquist plots of CN and D-CN.
