2020年1月24日 · Poly (triazine imide) (PTI), a crystalline g-C 3 N 4, hosting two-dimensional nanoporous structure with an electron density gap of 0.34 nm, is highly promising for high-temperature hydrogen sieving because of its high chemical and thermal robustness. Currently, layered PTI is synthesized in potentially unsafe vacuum ampules in milligram quantities.

2019年1月17日 · Here, we report a simple bottom-up method to synthesize porous few-layer C 3 N 4, which involves molecule self-assembly into layered precursors, alcohol molecules intercalation, and subsequent thermal-induced exfoliation and polycondensation.

2025年3月14日 · Photocatalytic H2 and H2O2 production using graphitic carbon nitride (g-C3N4) offers promising renewable energy prospects but suffers from rapid exciton recombination, which can be mitigated by K+-insertion-driven enhanced interlayer electron–hole separation. However, limited K+ insertion remains a bottleneck due to inadequate ion-insertion channels. Herein, we present an engineered g-C3N4 ...
