  • Anionic polyacrylamide-assisted construction

    2020-7-5 · Abstract. Thin 2D/2D WO 3 /g-C 3 N 4 Step-scheme (S-scheme) heterojunction with carbon doping and bridge (C–W/N) was constructed with anionic polyacrylamide (APAM), in which APAM functioned as an assistant templet and a carbon source. APAM and WO 3 were inserted into g-C 3 N 4 nanosheet.
