Concerns about environmental pollution are at their peak, and industrial dyes and food adulteration have become common issues. In this regard, the degradation of pollutants using novel photocatalytic materials has always been a keen research interest. We prepared P-doped g-C₃N₄ (PCN) by thermal polymerization using triphenylphosphine and dicyandiamide precursors in this work. Meanwhile, the CuFe₂O₄ (CFO) was prepared through a hydrothermal synthesis route, and the entire composite (CFO/PCN) was prepared using the wet-impregnation technique. The physicochemical properties of the synthesized PCN and CFO/PCN nanocomposites were determined by XRD, FE-SEM, FTIR and XPS analysis. Herein, we put forward a new approach, with an environment-friendly and controllable way to design and synthesize the highly effective CFO/PCN for environmental remediation applications through this work, which significantly boosted photocatalytic activity for the elimination of CR as compared to pristine materials. The as-prepared 30% CFO/PCN shows higher rate constant (4.1 × 10⁻² min⁻¹), which is 3.5, and 2.8 times higher than PCN (1.15 × 10⁻² min⁻¹), CFO (1.44 × 10⁻² min⁻¹). Photo-oxidation of CR over 30% CFO/PCN resulted in 98.3% degradation within 90 min. Photoluminescence studies of the as-prepared composites showed that 30% CFO/PCN had the lowest charge recombination rate among the as-prepared composites. Thus, this work demonstrates a synthesis of low-cost and robust CuFe₂O₄/P-g-C₃N₄ p-n heterostructure composite for environmental remediation applications.

对环境污染的担忧达到顶峰，工业染料和食品掺假已成为普遍问题。在这方面，使用新型光催化材料降解污染物一直是研究热点。在这项工作中，我们使用三苯膦和双氰胺前体通过热聚合制备了 P 掺杂的 gC ₃ N ₄ (PCN)。同时，通过水热合成路线制备了CuFe ₂ O ₄ (CFO)，并采用湿法浸渍技术制备了整个复合材料(CFO/PCN)。通过XRD、FE-SEM、FTIR和XPS测定合成的PCN和CFO/PCN纳米复合材料的理化性质分析。在此，我们提出了一种新的方法，通过这项工作以一种环境友好和可控的方式设计和合成用于环境修复应用的高效 CFO/PCN，与原始材料相比，显着提高了消除 CR 的光催化活性。 . 所制备的 30% CFO/PCN 显示出更高的速率常数 (4.1 × 10 ^-2 min ^{-1 )，为 3.5，是 PCN (1.15 × 10 -2} min ^-1 )、CFO (1.44 × 10) 的2.8 倍^-2分钟^-1）。超过 30% CFO/PCN 的 CR 光氧化导致 90 分钟内降解 98.3%。所制备的复合材料的光致发光研究表明，在所制备的复合材料中，30% CFO/PCN 的电荷复合率最低。因此，这项工作展示了一种用于环境修复应用的低成本且坚固的CuFe ₂ O ₄ /PgC ₃ N _{4 pn 异质结构复合材料的合成。}
