a Synthesis of dual-layer carbon nitride (DCN) by CVD with spin-coating pretreatment. b Comparison of different film-forming methods. Surface roughness is calculated by Root-mean square height. Photocurrent density is measured in 0.1 M Na2SO4 at 1.23 eV vs. RHE. Values are given as average (n = 3) with standard deviation. c Relationship between film thickness and concentration of polymer matrix during pretreatment. Values are given as average (n = 3) with standard deviation. d Cross-section and (e) surface view SEM image of DCN electrode (compared to standard CN, Fig. S5). Source data are provided as a source data file.
