The accurate identification and quantification of volatile organic compounds is imperative in addressing environmental concerns, medical diagnostics, industrial safety. Thus, the current study focuses on fabrication heterostructures based In2O3–p-type metal oxides (i.e., In2O3-CuO, In2O3-Co3O4, In2O3-Mn3O4, In2O3-NiO) utilizing a hydrothermal approach. Various techniques were utilized to characterize detail. Among tested sensors towards various analytes, In2O3-Co3O4-based sensor disclosed better response 2.3 ppm acetone (C3H6O) at 100 °C. also demonstrated outstanding sensitivity (2.38 ppm−1), an extremely low limit detection (0.142 ppb), humidity resistance, fast response-recovery time. improved C3H6O gas sensing performance could be associated with enhanced interfacial synergy In2O3-Co3O4 heterostructure creation oxygen vacancies, reduced band gap, higher specific surface area revealing additional active sites enable adequate molecules adsorption. work further discusses theoretical procedure that was evaluated using crystal field theory determine strength cobalt ions identify which electronic state mostly exploited form possible heterostructure. These results provide viable pathway regulate characteristics concentration for practical health assessment.

Indium oxide (In 2 O 3 ) nanorods (NRs) have emerged as a promising material for ethanol gas detection due to their high surface-to-volume ratio, excellent electrical conductivity, and robust chemical stability. These one-dimensional nanostructures provide enhanced surface activity efficient charge carrier transport, making them ideal sensing applications. The as-synthesized In NRs based sensor has exhibited response of 45.8–50 ppm at 225 °C, with time 273 s. experiments were carried different operating temperature (150–275) examine the optimum working it was observed worked best °C. mechanism is on interaction between molecules adsorbed oxygen species surface, leading measurable changes in resistance. Advances synthesis techniques, such hydrothermal growth, vapor deposition, doping, enabled fabrication tailored properties, optimizing sensitivity, selectivity, times. Additionally, integrating catalytic dopants composites further improved lower temperatures under challenging conditions. This study highlights potential high-performance sensing, paving way innovative applications industrial safety, especially drilled pile monitoring.
