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: This paper presents a quartz crystal microbalance sensor based on SnO2 NFs/PDA composite with high sensitivity and selectivity to formaldehyde gas. The sensor exhibited excellent sensing characteristics over a wide range of formaldehyde concentration, including high sensitivity, short response/recovery times, and high linearity. The adsorption mechanism of formaldehyde gas was attributed to hydrogen bonding and aldehyde ammonia Schiff base interactions.

Summary: In this study, SnO2 nanofibers and their modifications (Cd doping and making a composite with reduced graphene oxide) were synthesized via electrospinning and used for CO gas sensing. The enhanced sensing properties of Cd-doped SnO2-RGO nanofibrous mat, compared to other counterparts, can be attributed to the p-type behavior of RGO inside the nanofibers, catalytic activity, and the addition of new oxidation sites for cadmium elements, providing flexible and optimal gas sensing.

Summary: We report a high-performance gas sensing strategy for the selective detection of Listeria monocytogenes, which is realized using n-CdO/n-SnO2 hetero-nanofibers with controllable compositions. The CdO/SnO2 nanofibers show enhanced 3H-2B sensing properties due to the modulation of n-CdO/n-SnO2 heterojunctions and the doping effect of Cd2+ ions. The variation of Cd/Sn molar ratios significantly affects the sensing performance, and 5 mol% CdO/SnO2 nanofibers exhibit the best response to 5 ppm 3H-2B at 260 degrees C, along with excellent stability and selectivity.

Summary: An optimized acetone gas sensor based on Ti3C2/alpha-Fe2O3 (TF) composite materials was synthesized using microwave and etching methods. The TF composites exhibited improved gas-sensitive performance to acetone due to the increased specific surface area and surface defects, as well as the excellent electrical conductivity and high free charges transfer ability of Ti3C2 MXene. The response of TF gas sensor to 100 ppm acetone was significantly higher than pure alpha-Fe2O3 gas sensor, with a lower detection limit of 1 ppm. The TF gas sensor also demonstrated excellent selectivity, long-term repeatability, and stability for acetone.
