Harmful chemicals are always found in the environment and it is necessary to construct a viable sensor to detect those chemicals. In order to construct an electrochemical sensing platform, designing an electrode using bismuth mixed oxides are more important and which grabbed more attention due to its high electrocatalytic ability and conductivity. In this literature, we report a facile synthesis of thorn apple like structured pure bismuth molybdate (Bi₂MoO₆) using a simple hydrothermal assisted one-step calcination method and we report a facile method to sense 4-cyanophenol by electrochemical technique. Bi₂MoO₆ modified (Glassy Carbon electrode) GCE possess two linear ranges 0.1–39.1 µM and 46.6–110.1 µM with excellent detection limit 0.008297 µM and 0.01097 µM. Also, this novel sensor is steady with good stability, repeatability, and reproducibility. Successfully, the environmental water sample is analyzed as a real sample with a feasible and quantification results which were compared with HPLC analysis.

有害化学物质总是存在于环境中，因此有必要构建一个可行的传感器来检测这些化学物质。为了构建电化学传感平台，使用铋混合氧化物设计电极更加重要，并且由于其高的电催化能力和电导率而受到越来越多的关注。在该文献中，我们报告了使用简单的水热辅助一步煅烧方法轻松合成刺苹果状结构化纯钼酸铋（Bi ₂ MoO ₆）的方法，并报道了一种通过电化学技术感测4-氰基苯酚的简便方法。Bi ₂ MoO ₆改进的（玻璃碳电极）GCE具有两个线性范围0.1–39.1 µM和46.6–110.1 µM，具有极好的检测限0.008297 µM和0.01097 µM。而且，这种新型传感器稳定，具有良好的稳定性，可重复性和可重复性。成功地将环境水样品分析为真实样品，并提供了可行的定量结果，并与HPLC分析进行了比较。
