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 steam-assisted method for preparing polymeric carbon nitride (PCN) nanosheets with/without doping for superior photocatalytic H2 evolution, using a green gas template, i.e. steam, decomposed from the recyclable steam source Mg(OH)2.
