Abstract

In this study, La-doped ZrO₂/g-C₃N₄ nanocomposites were synthesized and remarkably, 0.8% La-doped ZrO₂/g-C₃N₄ exhibited an outstanding degradation efficiency of 87% (k = 11.301 × 10⁻³ min⁻¹). The enhanced photocatalytic performance is due to the synergistic effects of lanthanum and g-C₃N₄, which promote charge separation and increase the number of active sites. A built-in electric field exists according to the charge density difference and electrostatic potential results. At 300 K, the nanocomposite is thermally, energetically, and dynamically stable. Our results provide valuable insights into the design and development of efficient photocatalysts for the removal of organic contaminants from aqueous environments.

用于曙红黄光降解的掺 La ZrO2/g-C3N4 纳米复合材料的合成：实验与理论的综合研究

本研究合成了掺 La 的 ZrO2/g-C3N4 纳米复合材料，其中掺 La 的 0.8% ZrO2/g-C3N4 纳米复合材料的降解效率高达 87%（k = 11.301 × 10-3 min-1）。光催化性能的提高得益于镧和 g-C3N4 的协同效应，它们促进了电荷分离，增加了活性位点的数量。根据电荷密度差和静电位结果，存在一个内置电场。在 300 K 的温度下，纳米复合材料具有热稳定性、能量稳定性和动态稳定性。我们的研究结果为设计和开发用于去除水环境中有机污染物的高效光催化剂提供了宝贵的见解。
