Abstract

The focus of this work is to develop a sensitive and reliable acetone gas sensor using the Pt-modified Co₃O₄/CoMoO₄ heterojunction derived from metal-organic frameworks (MOFs). Pt-loaded Co₃O₄/CoMoO₄ heterojunction was successfully prepared by the surface redox method, and the composites exhibited high sensitivity and selectivity for acetone with a low detection limit. By modifying the Co₃O₄/CoMoO₄ material with platinum loading, the sensor achieved a response of 24.12 to 20 ppm acetone, which was significantly better than that of the pure Co₃O₄/CoMoO₄ heterojunction. This work not only improves acetone detection strategies, but also enhances the potential for industrial and medical VOC monitoring applications.

基于铂改性 Co3O4/CoMoO4 异质结的增强型丙酮气体传感器

本研究的重点是利用源自金属有机框架（MOFs）的铂修饰 Co3O4/CoMoO4 异质结开发一种灵敏可靠的丙酮气体传感器。利用表面氧化还原法成功制备了铂负载 Co3O4/CoMoO4 异质结，该复合材料对丙酮具有高灵敏度和高选择性，且检出限低。通过对 Co3O4/CoMoO4 材料进行铂负载修饰，传感器对 20 ppm 丙酮的响应达到了 24.12，明显优于纯 Co3O4/CoMoO4 异质结。这项工作不仅改进了丙酮检测策略，还提高了工业和医疗挥发性有机化合物监测应用的潜力。
