Ti3C2Tx/PEDOT:PSS hybrid materials for room-temperature methanol sensor

A blend of PEDOT:PSS and Ti3C2Tx with the mass ratio of 4:1 is developed to fabricate a methanol gas sensor with a high response ratio of the largest response and the second largest response 5.54 and improvement of response compared to pure PEDOT:PSS and pure Ti3C2Tx tested at room temperature. [Display omitted] It is essential to develop a methanol gas sensor with high selectivity and low working temperature for human health and environmental monitoring. In this work, a blend of PEDOT:PSS and Ti3C2Tx with the mass ratio of 4:1 is developed to fabricate a methanol gas sensor. It possesses a high response ratio of the largest response and the second largest response 5.54 and an enhanced response compared to pure PEDOT:PSS and pure Ti3C2Tx tested at room temperature. These findings may pave the way towards design of the MXenes based high-performance gas-sensing materials in the future.
