dc.description.abstract-translatedWe report the development of the C3N4 structure by integrating two different structures: (i) two identical layers as AAstacked C3N4 and (ii) intercalating one different layer between two identical layers as ABA stacked C3N4. This in turn endows C3N4 with significantly promoted charge migration, up-shifted conduction-band (CB) level, enhanced CB potential from -0.89 eV (AA-stacked C3N4) to -1.03 eV (ABA-stacked C3N4), broadened band gap as well as enhanced surface area, all of which favor the enhancement of the photocatalytic performance. The optical absorption level exhibited significant enhancement in the visible light region when shifting from AA-stacked C3N4 to ABA-stacked C3N4, where the absorption edge moves from = 508.1 = 454.1 nm. This corresponds to the direct optical band gap of 2.44 eV 2.73 eV, which is well matched with the solar spectrum and the sufficient negative CB potential for H+/H-2 reduction. Based on these results, we can conclude that AA-stacked and ABA-stacked C3N4 satisfies all the requirements to be efficient photocatalysts. This study will significantly improve the search efficiency and considerably aid the experimentalists in the exploration of novel photocatalysts.en
