Lead titanate (PbTiO₃) and (Ag–Fe) codoped Lead titanate (PbTiO₃) nanoparticles were synthesized by hydrothermal method and the prepared samples were annealed at 600 °C. The synthesized nanoparticles were described by physicochemical methods and analyzed the morphology, phase and elemental composition. To examine the impact of the nanoparticles on color degradation, different trial parameters, for example, pH (2, 4 and 6) conditions at different time periods and starting dye concentration was optimized. Ag–Fe co-doped PbTiO₃ nanoparticles degraded the dye with 80.40% at pH = 6 under UV light. The highest photocatalytic activity of (Ag–Fe) codoped PbTiO₃ nanoparticles was attributed to the endorsed charge separation and the enhanced adsorption capacity. Furthermore, the catalyst was found to be reusable and stable.

采用水热法合成了钛酸铅（PbTiO ₃）和（Ag-Fe）共掺杂的钛酸铅（PbTiO ₃）纳米粒子，并将制备的样品在600℃下退火。通过物理化学方法描述了合成的纳米粒子，并分析了其形态，相和元素组成。为了检查纳米颗粒对颜色降解的影响，优化了不同的试验参数，例如在不同时间段和起始染料浓度下的pH（2、4和6）条件。Ag-Fe共掺杂的PbTiO ₃纳米粒子在紫外光下，在pH = 6时，染料的降解率为80.40％。（Ag-Fe）共掺杂PbTiO ₃的最高光催化活性纳米颗粒归因于认可的电荷分离和增强的吸附能力。此外，发现该催化剂是可重复使用的和稳定的。
