The Cr-doped CeO2 nanomaterials were prepared by a simple hydrothermal method. Morphological analysis revealed that Cr doping altered the morphology and size of particles. Gas sensing tests results showed Cr/Ce-2 has highest response (Ra/Rg = 15.6 @ 10 ppm), which was 12.58 times higher than pure sensor. Furthermore, optimal operating temperature reduced from 210 °C to 170 °C. sensor also displayed outstanding repeatability gas selectivity. improved performance can be attributed its smaller grain porosity compared CeO2. In addition, oxygen vacancies played pivotal role in improving gas-sensing performance. present work provides new CeO2-based gas-sensitive material for detection n-butanol.

Perovskite oxide-based materials (ABO3) have gained much attention as promising candidates for advanced gas-sensing applications due to their versatile structures, tunable properties, and excellent stability. This review discusses recent developments in the synthesis, structural optimization, functionalization of perovskites enhance performance. Strategies such doping, creating oxygen vacancies, tuning morphology, forming heterojunctions significantly improved sensitivity, selectivity, response, recovery times. Specific advances include incorporation nanostructures, porous morphologies, catalytic elements, which optimized adsorption desorption processes various target gases, including volatile organic compounds, NO2, CO2. Mechanistic insights into role surface defects, charge carrier dynamics are also addressed. These position perovskite important components next-generation gas sensors environmental monitoring industrial applications.
