A highly efficient visible-light-driven photocatalyst based on iodinated graphitic carbon nitride nanosheets (IGCNSs) has been prepared by facilely ball-milling graphitic carbon nitride (GCN) in the presence of iodine.
A one-step electrochemical method for synthesis of ultrathin g-C3N4 nanosheets is reported. This method does not need dangerous reagents and largely reduces the reaction time.
