Vacancy defect graphitic carbon nitride (g-C3N4) and conjugated polyimide (PI) polymer photocatalysts have become increasingly recognized as metal-free featuring an appropriate bandgap. The narrow absorption spectrum of visible light the rapid recombination rate photoexcited charge carriers in PI polymers g-C3N4 impede its photocatalytic performance. presence oxygen vacancies (OVs) photocatalysts, well nitrogen (NVs) (CVs) g-C3N4, can significantly enhance migration photogenerated electrons. Adding to improve electronic structure band gap width greatly efficiency g-C3N4. Defect engineering is important for increasing ability PI-polymer There remains a notable absence thorough review papers covering synthesis, characterization, applications vacancy-rich photocatalysis. This paper examines roles OVs PI-polymer, NVs, CVs thoroughly summarizes preparation approaches employed before after, during polymerization. scrutinizes spectroscopic characterization techniques, such EPR, XPS, PAS, XRD, FTIR, NMR, vacancy analysis. We also reviewed role vacancies, which include absorption, carrier separation, transfer dynamics. could serve comprehensive understanding, vacancy-engineered design framework, practical guide synthesizing characterizing.
