A facile tert-butyl nitrite-assisted preparation of deamino graphitic carbon nitride (DA-gCN) as a photocatalyst for the C-H arylation of heteroarenes using anilines as radical source

Turkish Journal of Chemistry, 2023
In pristine graphitic carbon nitride (g-CN), amino groups often function as structural defects that trap photogenerated charges, resulting in low photocatalytic activity as well as reaction with nitrite, aldehyde, etc., ensuing in poor product yield. Without significantly altering the optical characteristics, the removal of amino groups is necessary to

Copper single-atoms embedded in 2D graphitic carbon nitride for the CO2 reduction [PDF]

npj 2D Materials and Applications, 2021
We report the study of two-dimensional graphitic carbon nitride (GCN) functionalized with copper single atoms as a catalyst for the reduction of CO2 (CO2RR). The correct GCN structure, as well as the adsorption sites and the coordination of the Cu atoms,

Enhancing removal of hexavalent chromium using biochar, graphitic carbon nitride (GCN) and ZnFe-LDH from wastewater

Digest Journal of Nanomaterials and Biostructures
Here we prepared co-pyrolyzed, biochar, GCN and LDH and compared for their hexavalent chromium (Cr(VI)) adsorption capacity. Several factors such as aqueous pH, sorption contact time, metal concentration, sorbent dose and recyclability of the sorbents were investigated to assess the potential of biochar, LDH and GCN. The results showed that the maximum
