Photocatalytic overall water splitting by graphitic carbon nitride

InfoMat, 2021
Photocatalytic overall water splitting (OWS) without using any sacrificial reagent to realize H2 and O2 production in the stoichiometric ratio of 2:1 is viewed as the “holy grail” in the field of solar fuel production.

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 [PDF]

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 ...

Sugarcane bagasse supported graphitic carbon nitride for photocatalytic conversion of carbon dioxide

Catalysis Communications, 2022
The sugarcane bagasse (SB) was recycled to support graphitic carbon nitride (gCN) for photocatalytic application. By tuning the hydrothermal process, the SB-supported gCN could convert carbon dioxide (CO2) into monoxide or methanol under the illumination
