Water pollution has increased swiftly, especially the dyes from industries that have disturbed aquatic eco-system. Photocatalytic degradation (PCD) is one of the attractive methods to eliminate dyes from industrial effluents. Zirconium phosphate (ZP) nanoparticles were synthesized by combustion method using zirconyl nitrate and phosphorous pentoxide as precursors. The obtained ZP was characterized by powder X-ray diffractogram, Fourier transform infrared, scanning electron microscopy, high-resolution transmission electron microscopy, Raman spectroscopy, photoluminescence spectroscopy, Brunauer–Emmett–Teller surface area. PCD was carried out using methylene blue as a model pollutant in aqueous medium in the presence of UV light irradiation with different concentrations of dye, catalyst and pH. Higher degradation efficiency was observed in basic medium. ZP is employed as a catalyst to form nitrides from aldehydes using different solvents with different aldehydes.

燃烧法绿色合成磷酸锆：光催化应用及微波辅助催化醛转化腈
水污染迅速增加，特别是来自扰乱水生生态系统的工业的染料。光催化降解 (PCD) 是从工业废水中去除染料的一种有吸引力的方法。以硝酸氧锆和五氧化二磷为前驱体，通过燃烧法合成磷酸锆（ZP）纳米颗粒。通过粉末X射线衍射图、傅里叶变换红外、扫描电子显微镜、高分辨率透射电子显微镜、拉曼光谱、光致发光光谱、Brunauer-Emmett-Teller表面积表征所获得的ZP。PCD 使用亚甲蓝作为水介质中的模型污染物，在不同浓度的染料、催化剂和 pH 值的紫外线照射下进行。在碱性培养基中观察到更高的降解效率。ZP 用作催化剂，使用不同的醛类溶剂从醛类形成氮化物。
