Graphic carbon nitride polymer was modified with transition bimetals compounds by impregnation of pre-prepared g-C₃N₄ in aqueous solution of ammonium molybdate and vanadate. The prepared hybrid material was characterized by XRD, SEM, TEM, FT-IR, XPS and N₂ adsorption–desorption techniques to determine its surface morphology, composition and structure. The results revealed that VO_x-MoO_y single molecular layer incorporated into g-C₃N₄ molecule framework by interaction between host and guest was fabricated. The hybrid composite was employed as catalyst for styrene oxidation to benzaldehyde using molecular oxygen as oxidant. The results indicated that the composite was highly active and selective for styrene oxidation, giving TON 458.8 mol/mol_(Mo+V) and 96.7% selectivity to benzaldehyde. The correlation between high activity and surface properties the catalyst was explored.

通过在钼酸铵和钒酸铵水溶液中浸渍预先制备的gC ₃ N ₄，用过渡双金属化合物对图形氮化碳聚合物进行改性。通过XRD、SEM、TEM、FT-IR、XPS和N ₂吸附-解吸技术对制备的杂化材料进行表征，以确定其表面形貌、组成和结构。结果表明，VO _x -MoO _y单分子层并入 gC ₃ N ₄通过主体和客体之间的相互作用制造了分子框架。该杂化复合材料用作以分子氧为氧化剂将苯乙烯氧化为苯甲醛的催化剂。结果表明，该复合材料对苯乙烯氧化具有高活性和选择性，TON 为 458.8 mol/mol _(Mo+V)，对苯甲醛的选择性为 96.7%。探讨了催化剂的高活性与表面性质之间的相关性。
