Herein, we investigate the effect of metal-free heteroatom doping (B, O, P, and S) on the structural, electronic, and photocatalytic properties of graphitic carbon nitride (C$_3$N$_4$) for H$_2$O$_2$ production under simulated solar irradiation. While pristine C$_3$N$_4$ exhibits stacked nanosheets, doping induces disorder, partial exfoliation, and changes in interlayer spacing, confirming successful heteroatom incorporation and modification of the electro","authors_text":"Bruna F.
