Summary: The morphological and structural characteristics of semiconductors significantly influence their gas sensing abilities. By synthesizing a cobalt oxide nanofibers/cadmium sulfide nanospheres hybrid, the sensor performance for acetone detection was greatly improved at room temperature. The heterojunction between CdS and Co3O4, as well as the excitation of light on carrier concentration, played a key role in enhancing the sensor's response to acetone gas.

Summary: In this study, a novel SnO2 nanorod/spindle-like Fe2O3 heterostructure was successfully fabricated through a simple two-step hydrothermal route, which showed improved gas sensing performance on volatile organic compounds compared to pure Fe2O3. The enhanced gas-sensitivity performance of the hierarchical SnO2/Fe2O3 heterostructures can be attributed to the synergistic effect and heterojunction of the interface between spindle-like Fe2O3 and SnO2 nanorod. This research may provide new insight and a rational strategy for upgrading the sensing performance of certain semiconductor metal oxide materials through the design of novel layered nanostructures in the future.

Summary: A mixed potential gas sensor using yttria-stabilized zirconia (YSZ) solid electrolyte was developed for acetone and hydrogen sulfide detection, with improved specificity achieved by adjusting operating temperature and fabricating a double-sensing electrode sensor. The sensor exhibited high sensitivity to both acetone and hydrogen sulfide (H2S) when using NiAlGaO4 sensing electrode and Pt reference electrode, while the double-sensing electrode sensor with Sm1.2Sr0.8CoO4 material showed good specificity to acetone against H2S due to differences in sensing properties. The low detection limit of the sensor was 1 ppm with a sensitivity of 21 mV/decade, showing great potential for non-invasive breath analysis.

Summary: In this work, hierarchical heterostructured alpha-Fe2O3/alpha-MoO3 hollow spheres were successfully fabricated for gas sensing applications. The sensor exhibited high sensitivity and selectivity towards aniline at 217 degrees C, with a higher response to 30 ppm ANI compared to pristine alpha-Fe2O3 and alpha-MoO3 sensors, along with a fast response time. The detection limit to ANI was further decreased to 0.01 ppm and the gas sensing mechanism was speculated to involve the oxidation of ANI to azobenzene by chemisorbed oxygen. The study demonstrates the potential of this metal oxide composite for high-performance gas sensor applications.
