Photocatalytic Evolution of Hydrogen from Alcohol–Aqueous Solutions using Nanocrystalline Carbon Nitride Modified with Magnesium Chloride Under the Visible Light Irradiation
Samples of nanocrystalline graphite-like carbon nitride (CGCN) modified with magnesium chloride have been obtained. The synthesized Mg-CGCN samples have been characterized by UV and IR spectroscopies, X-ray diffraction, energy dispersive X-ray analysis, and scanning electron microscopy. It is found...

| description | Samples of nanocrystalline graphite-like carbon nitride (CGCN) modified with magnesium chloride have been obtained. The synthesized Mg-CGCN samples have been characterized by UV and IR spectroscopies, X-ray diffraction, energy dispersive X-ray analysis, and scanning electron microscopy. It is found that Mg-CGCN exhibits 60% higher photocatalytic activity in the reaction of hydrogen evolution from aqueous ethanol solutions under visible light than undoped CGCN. This may be related to a change in electrophysical characteristics (potentials of allowed bands) resulting from the incorporation of Mg
2+
ions into the CGCN structure, improved dissociation of photogenerated charges, and inhibition of their recombination. |
