The complex was prepared with preyssler polyoxoanion and transition metal (Mo), a cationic surfactant as a connector. It has tuneable physical and chemical potential which has been exploited to study novel properties. A new technique of shock wave impulses is also used on the Mo-PHP complex. Extensive use of cationic surfactants could impact accumulation in the environment set off the surfacing of bacterial resistance. Due to the electrostatic binding to bacterial surface, the hydrophobic parts of cationic surfactants tend to penetrate bacterial cell walls and may cause membrane lysis and bacteria death. The surfactant-supported and direct release of metal ions from PWMo against bacterial resistance has been explained schematically. The dielectric study helps to understand the dissociation of cations that generate polarons and the hopping mechanism with neighbouring vacant atomic sites. Structural analysis confirms the formation of cationic surfactant incorporated polyoxoanion (Mo-PHP). A hexagonal shape-like structure for the PHP complex has been observed. The Mo-incorporated PHP complex was characterized using UV-visible (UV), Fourier Transform-infrared (IR), Raman spectra, scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques.
该配合物由普雷司勒多金属氧酸盐和过渡金属（钼）以及作为连接体的阳离子表面活性剂制备而成。它具有可调节的物理和化学势，已被用于研究新特性。一种冲击波脉冲新技术也应用于钼 - PHP配合物。大量使用阳离子表面活性剂可能会影响其在环境中的积累，引发细菌耐药性问题。由于阳离子表面活性剂与细菌表面的静电结合，其疏水部分往往会穿透细菌细胞壁，可能导致膜裂解和细菌死亡。已示意性地解释了表面活性剂支持的以及PWMo中金属离子对细菌耐药性的直接释放。介电研究有助于理解产生极化子的阳离子解离以及与相邻空原子位点的跳跃机制。结构分析证实了掺入阳离子表面活性剂的多金属氧酸盐（钼 - PHP）的形成。已观察到PHP配合物呈六边形结构。采用紫外可见光谱（UV）、傅里叶变换红外光谱（IR）、拉曼光谱、扫描电子显微镜（SEM）、能量色散光谱（EDS）和X射线衍射（XRD）技术对掺入钼的PHP配合物进行了表征。
