“…9 (a) shows the photocatalytic degradation capacity of the final product and two precursors and commercially available anatase TiO 2 nanoparticles. The adsorption of organic molecules onto TiO 2 surfaces involves physical van der Waals forces, electrostatic interactions, and chemical bonding with acidic sites and hydroxyl groups [ 65 ]. Wiedmer et al reported that six commercial TiO 2 species showed the strongest degradation to MB at neutral pH 6.7 out of pH 3, 6.7, and 9 [ 66 ].…”

As global urbanization intensifies, there is an increasing need for highly sensitive and accurate environmental monitoring devices that can meet the demands of specific gas sensing applications with low power consumption. This study focuses on enhancing the sensitivity of MXene‐based chemiresistive sensors for detecting CO2(g) and NO2(g) under zero‐bias operation. This study shows that lignin hybridization effectively improves the sensitivity of a Ti3C2Tx MXene‐based chemiresistive sensor; under zero‐bias operation, lignin hybridization increases the sensitivity to 15 ppm NO2(g) and CO2(g) by 157.38% and 297.95%, respectively. When deposited on a flexible substrate, the MXene/lignin flexible sensor shows a similar response and sensitivity to 15 ppm NO2(g) and CO2(g) under 38° curvature compared to the planar sensor. Consequently, the MXene/lignin hybrid sensor is attractive for room temperature and zero‐bias NO2(g) and CO2(g) detection. The MXene/lignin flexible sensor serves as a model system for advanced solid‐state sensory platforms suitable for curved structures.image
