This study reports a novel hollow CuO@CuS material used as a catalyst for enzyme free glucose detection. CuO@CuS is successfully synthesized by a facile in-situ growth method. The obtained CuO@CuS exhibits a hollow structure with a CuS rich surface. Compared to CuO spheres, electrochemical results reveal that the CuO@CuS material exhibits a much higher catalytic activity toward glucose oxidation due to synergistic effect between CuO and CuS. The as-prepared CuO@CuS produces a high sensitivity, a fast sensing response, a wide linear range in concentrations of 1-1000 μM, and an excellent selectivity, thus prove to be a promising catalyst for enzyme free glucose detection.
本研究报道了一种新型的空心 CuO@CuS 材料，可作为无酶葡萄糖检测的催化剂。通过简便的原位生长方法成功合成了 CuO@CuS。所获得的 CuO@CuS 具有富 CuS 的表面的空心结构。与 CuO 球相比，电化学结果表明，由于 CuO 和 CuS 之间的协同作用，CuO@CuS 材料对葡萄糖氧化具有更高的催化活性。所制备的 CuO@CuS 具有高灵敏度、快速传感响应、在 1-1000μM 浓度范围内的宽线性范围和优异的选择性，因此被证明是一种有前途的无酶葡萄糖检测催化剂。
