Herein we report a facile and low cost microwave irradiation method was adapted to design and fabricate the NiFe2O4/g-C3N4 hybrid catalyst. The different amount of NiFe2O4 (5, 10 and 15 wt%) was incorporated in to g-C3N4 and various characterizations such as XRD, SEM, TEM, RAMAN, UV, PL and BET analysis were exploit to know the optical, morphological and textural behavior. XRD and TEM results suggest that cubic structure and aggregated nanoparticles in the range of 25–35 nm was uniformly decorated on the surface of g-C3N4 nanosheets. The incorporated NiFe2O4 in to g-C3N4 could dominate in the surface area with porous nature and tuning the optical property in the visible light region. This could improve the rapid photo degradation efficiency of methyl orange (MO) and rhodamine B (RhB) under stimulated visible light irradiation. The 15 wt% NiFe2O4/g-C3N4 show outstanding removal efficiency of 97% and high apparent constant (0.427 min−1) and unbelievable stability towards MO dye. The rate of recombination is greatly lowered, and the composite catalyst's enhanced absorption of visible light plays a critical role in improving photocatalytic performance. On the basis of the data, the improved behaviour of the photocatalyst was comprehensively discussed.

微波诱导反尖晶石 NiFe2O4 装饰 g-C3N4 纳米片增强可见光光催化活性

在此,我们报告了一种适用于设计和制造 NiFe 2 O 4 /gC 3 N 4混合催化剂的简便且低成本的微波辐射方法。将不同量的 NiFe 2 O 4(5、10 和 15 wt%)加入到 gC 3 N 4 中,并利用各种表征,如 XRD、SEM、TEM、RAMAN、UV、PL 和 BET 分析来了解光学,形态和纹理行为。XRD 和TEM 结果表明立方结构和25-35 nm 范围内的聚集纳米粒子均匀地装饰在gC 3 N 4纳米片的表面上。掺入的 NiFe 2O 4 in to gC 3 N 4可以在具有多孔性质的表面积中占主导地位,并在可见光区域调整光学特性。这可以提高甲基橙 (MO) 和罗丹明 B (RhB) 在受激可见光照射下的快速光降解效率。15 wt% NiFe 2 O 4 /gC 3 N 4表现出出色的去除效率 97% 和高表观常数 (0.427 min -1) 和令人难以置信的对 MO 染料的稳定性。复合率大大降低,复合催化剂对可见光的增强吸收对提高光催化性能起着关键作用。在这些数据的基础上,对光催化剂的改进行为进行了全面的讨论。
