Solvothermal modification of graphitic C3N4 with Ni and Co phthalocyanines: Structural, optoelectronic and surface properties

Nanocomposites for photocatalytic applications were obtained by alchothermal modification of g-C₃N₄ with cobalt(ii) and nickel(ii) phthalocyanine complexes. The nanocomposites demonstrated higher photocatalytic activity than the bare matrix and stability under actinic irradiation. In the optoelectronic structure of the composites, the E_g value of the g-C₃N₄ matrix increased to 3.05 eV, while for MPc agents, it decreased from 1.96 to 1.82 eV.
