A Comparative Review of Graphene and MXene-Based Composites towards Gas Sensing

Molecules, Journal Year: 2024, Volume and Issue: 29(19), P. 4558 - 4558

Published: Sept. 25, 2024

Graphene and MXenes have emerged as promising materials for gas sensing applications due to their unique properties superior performance. This review focuses on the fabrication techniques, applications, mechanisms of graphene MXene-based composites in sensing. Gas sensors are crucial various fields, including healthcare, environmental monitoring, industrial safety, detecting monitoring gases such hydrogen sulfide (H2S), nitrogen dioxide (NO2), ammonia (NH3). Conventional metal oxides like tin oxide (SnO2) zinc (ZnO) been widely used, but offer enhanced sensitivity, selectivity, response times. Graphene-based can detect low concentrations H2S NH3, while functionalization improve gas-specific selectivity. MXenes, a new class two-dimensional materials, exhibit high electrical conductivity tunable surface chemistry, making them suitable selective sensitive detection gases, VOCs humidity. Other metal-organic frameworks (MOFs) conducting polymers, also shown potential which may be doped into MXene layers sensitivity sensors.

Abstract Two-dimensional (2D) Ti 3 C 2 T x MXene-based materials have attracted widespread attraction in the field of energy storage owing to their high conductivity and accordion-like structure. However, challenges such as restacking oxidative degradation MXene structure lead poor stability, low conductivity, specific capacitance and, consequently, a energy, hindering extensive adoption at an industrial scale. In this study, ternary MXene/polyaniline (PANI)/ZnO (MPZ) composite has been synthesized via surface engineering two-dimensional using one-dimensional (1D) PANI nanowires ZnO nanoparticles enhance its stability while sustaining power. 1D act spacers prevent restacking, also exposing suppressed redox active sites 2D preventing it from being oxidized by forming porous conductive network all over MXene. provide additional electroactive p–n heterojunctions, thus enhancing faradaic reactions MPZ composite. As result, overall electrochemical performance are enhanced due synergistic interactions among individual components within At current density 0.1 A g −1 , exhibited maximum 651.96 F highest 32.59 Wh Kg maintaining power 60 W compared binary MP Furthermore, showcased exceptional cyclic 10 000 cycles with 94.75% 92.95% capacitive retention 0.6 40 mV s scan rate, respectively.
