摘要

Based on the distinctive characteristics of Layered Double Hydroxides (LDHs), extensive research has focused on their sensory properties and their application as electrochemical and gas sensors using various methods such as cataluminescence (CTL) and resistance measurements. In this study, we have rigorously examined the sensing capabilities of the Ni-Cr LDH sensor in the presence of acetone and ethanol at room temperature. Subsequently, we have compared these results with the sensing properties of the Ni-Cr-Al LDH and Ni-Cr LDH/TiO2 sensors under identical conditions, leading to a comprehensive discussion on the impact of Al3+ and titanium oxide on the sensors’ sensing properties. The Ni-Cr LDH/TiO2 sensor showed better sensitivity to acetone and ethanol than the other two sensors. Besides, the Ni-Cr LDH/TiO2 sensor exhibited shorter recovery and response times in the presence of acetone. Conversely, the Ni-Cr LDH sensor had quicker recovery and response times in the presence of ethanol, outperforming the other sensors.
