Description

technical field [0001] The present invention relates to a kind of benzene sensor, relate in particular to a kind of methyl benzoate sensor based on photoelectric coupling effect and preparation method thereof. Background technique [0002] Methyl benzoate is an important organic solvent. Yet the leakage of methyl benzoate can cause harm to the environment, can cause pollution to water body, soil and atmosphere, and methyl benzoate can form explosive mixture with air, meets naked flame, high heat energy and causes combustion explosion. . Therefore, it is necessary to develop a sensor with high selectivity to monitor the potential leakage of methyl benzoate during daily storage and transportation. Most of the current commercial methyl benzoate monitoring devices are based on the infrared detection principle, which has the problems of large volume and high price, and cannot achieve high selectivity detection of methyl benzoate. How to construct a cheap and portable sensor fo...
