The current work emphasized the facile fabrication of PCN/GO nanocomposites via a straight forward sonochemical method. The thermal polycondensation method was used for the preparation of graphitic carbon nitride (GCN) and phosphorous doped graphitic carbon nitride (PCN) photocatalysts using melamine and BmimPF₆ (1-Butyl-3-methylimidazolium hexafluorophosphate) precursors. Phosphorous doped g-C₃N₄ with different wt % ratio of phosphorous (0.05, 0.1, and 0.3%) was successfully fabricated and coupled with graphitic oxide (GO) for malathion degradation and bacterial disinfection. Phosphorous doping improved the electronic and textual properties of g-C₃N₄ and augmented solar light-responsive range. On the other hand, simultaneously, the GO support simultaneously facilitated the charge separation and transportation, which was validated by PL and EIS analysis. The extremely organized porous structure of PCN/GO nanosheets expanded active sites, quickened electron transmission rate, and caused strong adsorption of pollutants. Specific surface area (S_BET) of 0.1 wt% PCN/GO and PCN photocatalysts was 13.6840 and 2.8401 m² g⁻¹, respectively. The addition of peroxymonosulfate (PMS) in photodegradation processes augmented the photodegradation ability of nanocomposites due to the triggering of sulfate radical (SO₄•⁻) based advanced oxidation process. The influence of different reaction parameters, including a concentration of PMS, catalyst dosage, initial concentration of the pesticide, and pH, was also assessed in the photodegradation process. All the photodegradation processes followed the pseudo-first-order kinetics as the regression coefficient (R²), and values of linear graphs were from 0.95 to 0.98. The nanocomposite 0.1 wt% PCN/GO/PMS displayed the highest photodegradation efficiency, i.e., 98%, followed by 0.1 wt% PCN/GO (95%) and other photocatalysts. Similarly, 98% Escherichia coli (E. Coli) bacterial disinfection was observed for 0.1 wt% PCN/GO nanocomposite.

当前的工作强调了通过直接的声化学方法容易地制备PCN / GO纳米复合材料。使用三聚氰胺和BmimPF ₆（1-丁基-3-甲基咪唑六氟磷酸盐）前体，采用热缩聚法制备了石墨氮化碳（GCN）和磷掺杂的石墨氮化碳（PCN）光催化剂。成功制备了磷掺杂的gC ₃ N ₄（磷的重量百分比不同（0.05％，0.1％和0.3％）），并与氧化石墨（GO）结合用于马拉硫磷降解和细菌消毒。磷掺杂改善了gC ₃ N ₄的电子和文本性质并增加了太阳光响应范围。另一方面，GO支持同时促进了电荷的分离和运输，这已通过PL和EIS分析得到验证。PCN / GO纳米片的极其有序的多孔结构扩展了活性位点，加快了电子传输速率，并引起了污染物的强烈吸附。0.1wt％PCN / GO和PCN光催化剂的比表面积（S _BET）分别为13.6840和2.8401m ²  g ^-1。在光降解过程中添加过氧一硫酸盐（PMS）可以增强纳米复合材料的光降解能力，这是由于引发了硫酸根（SO ₄ • ^-）基于先进的氧化工艺。在光降解过程中，还评估了不同反应参数的影响，包括PMS的浓度，催化剂的用量，农药的初始浓度和pH值。所有的光降解过程都遵循拟一阶动力学作为回归系数（R ²），线性图的值在0.95至0.98之间。纳米复合物0.1wt％的PCN / GO / PMS显示出最高的光降解效率，即98％，其次是0.1wt％的PCN / GO（95％）和其他光催化剂。类似地，98％的大肠杆菌（E. 大肠杆菌中观察到0.1％（重量）PCN / GO纳米复合材料）细菌消毒。
