Porous ZnO-SnO2-Zn2SnO4 heterojunction nanofibers fabricated by electrospinning for enhanced ethanol sensing properties under UV irradiation

Yuanyi Zhang et al.

Summary: The porous ZnO-SnO2-Zn2SnO4 heterojunction nanofibers were prepared using electrospinning and high ramp rate heat treatment, showing significantly enhanced ethanol sensing capabilities under UV light irradiation. The response of ZnO-SnO2-Zn2SnO4 nanofibers to ethanol was much higher than that of pure Zn2SnO4 nanofibers, and remained effective even in high humidity conditions.

Hierarchical kiwifruit-like ZnO/ZnFe2O4 heterostructure for high-sensitive triethylamine gaseous sensor

Shuang Li et al.

Summary: In this study, hierarchical kiwifruit-like ZnO/ZnFe2O4 heterostructures were prepared and showed improved gas sensing performance with fast response/recovery time and long-term stability. The enhanced gas sensing mechanism is attributed to the intriguing architecture of the ZnO/ZnFe2O4 heterojunction with ultrathin nanosheets and abundant reactive sites. This work provides new opportunities for designing gas sensing materials through assembling multicomponent architectures.

0D/2D CdS/ZnO composite with n-n heterojunction for efficient detection of triethylamine

Jingjing Liu et al.

Summary: A novel CdS/ZnO composite with 0D/2D structure was successfully fabricated as an outstanding triethylamine sensor, exhibiting low operating temperature, high response value, fast response time, durable stability, excellent selectivity, and superior anti-interference ability. The enhanced gas sensing properties were attributed to the splendid 0D/2D structure, n-n heterojunction, and large specific surface area. This study paves the way for designing sensors with 0D/2D structure.

Porous In2O3 nanorods fabricated by hydrothermal method for an effective CO gas sensor

Pham Van Tong et al.

Summary: In this study, porous In2O3 nanorods with a diameter of about 10 nm and length of about 40 nm were fabricated and utilized as an effective CO gas sensor. The sensor showed the best gas sensing performance at a working temperature of 350 degrees C with a response value of about 3.5 for 400 ppm CO, and exhibited excellent stability and high selectivity to detect CO over interfering gases.
