The causal relationship between CHM and liver injury is much complex, and the clinical characteristics of DILI caused by CHM differ from those caused by WM.
Defect modulation usually has a great influence on the electronic structures and activities of photocatalysts. Here, atomically layered g-C 3 N 4 modified via defect engineering with nitrogen vacancy and cyanogen groups is obtained through two facile steps of thermal treatment (denoted as A-V-g-C 3 N 4 ). Detailed analysis reveals that the atomic-layered graphitic carbon nitride (2.3 nm) with defect engineering modifying provides more active sites and decreases the electron/hole transferring distances. More importantly, the defects that contain nitrogen vacancies and cyanogen groups extend the responsive wavelength to 650 nm, which effectively suppresses the quantum size effect of atomic-layered g-C 3 N 4 . Therefore, the as-obtained A-V-g-C 3 N 4 exhibited a photocatalytic H 2 evolution rate and apparent quantum yield of 3.7 mmol•g −1 •h −1 and 14.98% (λ > 420 nm), respectively. This work is expected to provide guidance for the rational design of atomic-layered g-C 3 N 4 .
