Herein, we have reported a novel composite of nitrogen doped reduced graphene oxide (N-rGO) and strontium zirconate (SrZrO₃). This new composite (N-rGO/SrZrO₃) was synthesized using the reflux method. The physicochemical properties of N-rGO/SrZrO₃ were determined using different advanced techniques such XRD, FE-SEM, EDX, FTIR and BET. Furthermore, a glassy carbon electrode was modified with N-rGO/SrZrO₃ (GCE-2). This modified electrode was employed for the sensing of HQ. The electrochemically active surface area (ECSA) of this modified electrode (GCE-2) was calculated by employing the Randles–Sevcik equation. Furthermore, GCE-2 exhibited a good detection limit (0.61 μM) including high selectivity towards HQ.

在此，我们报道了氮掺杂还原氧化石墨烯（N-rGO）和锆酸锶（SrZrO ₃）的新型复合材料。这种新的复合材料（N-rGO/SrZrO ₃）是使用回流法合成的。N-rGO/SrZrO ₃的物理化学性质是使用不同的先进技术确定的，例如 XRD、FE-SEM、EDX、FTIR 和 BET。此外，用N-rGO/SrZrO ₃ ( GCE-2 )对玻碳电极进行了改性。这种修饰电极被用于HQ的传感。该修饰电极 ( GCE-2 )的电化学活性表面积 (ECSA)采用 Randles-Sevcik 方程计算。此外，GCE-2表现出良好的检测限（0.61 μM），包括对 HQ 的高选择性。
