In this work, we have developed ytterbium tungstate (Yb₂WO₆) as an electrocatalyst through a simple co-precipitation method. The as-prepared catalyst was systematically investigated by various characterization techniques such as X-ray diffraction (XRD), Raman spectroscopy, field emission-scanning electron microscopy (FE-SEM) and energy-dispersive X-ray analysis (EDX). The as-developed Yb₂WO₆ was successfully applied to the electrochemical sensor (electrocatalyst) for sensitive and selective detection of antipsychotic drug chlorpromazine (CPZ). Interestingly, the Yb₂WO₆ modified screen printed carbon electrode (Yb₂WO₆/SPCE) shows an excellent electrocatalytic activity towards CPZ with extented wide linear response range and lower detection limit of 0.01–2520 µM and 0.001 µM, respectively. Moreover, the as-developed Yb₂WO₆/SPCE delivered an excellent selectivity even in the existence of cation, anion and some biologically co-interfering compounds. Furthermore, the Yb₂WO₆/SPCE displays an appreciable stability, and repeatability towards CPZ sensing. In addition, the Yb₂WO₆/SPCE was successfully applied to real sample analysis in CPZ tablet and urine samples with acceptable recoveries.

在这项工作中，我们通过简单的共沉淀方法开发了钨酸Y（Yb ₂ WO ₆）作为电催化剂。通过各种表征技术，如X射线衍射（XRD），拉曼光谱，场发射扫描电子显微镜（FE-SEM）和能量色散X射线分析（EDX），对制得的催化剂进行了系统的研究。已开发的Yb ₂ WO ₆已成功应用于电化学传感器（电催化剂），用于灵敏和选择性地检测抗精神病药物氯丙嗪（CPZ）。有趣的是，Yb ₂ WO ₆改性丝网印刷碳电极（Yb ₂ WO ₆/ SPCE）对CPZ表现出优异的电催化活性，线性响应范围广，检出限分别下限0.01–2520 µM和0.001 µM。而且，即使存在阳离子，阴离子和一些生物共干扰化合物，如此发展的Yb ₂ WO ₆ / SPCE仍具有出色的选择性。此外，Yb ₂ WO ₆ / SPCE显示出可观的稳定性和对CPZ感测的可重复性。此外，Yb ₂ WO ₆ / SPCE已成功应用于CPZ片剂和尿液样品中的真实样品分析，回收率令人满意。
