The remarkably enhanced visible-light-photocatalytic activity of hydrothermally synthesized WO3 nanorods: An effect of Gd doping

T. Govindaraj et al.

Summary: Novel Gadolinium doped WO3 nanorods (Gd@WO3 NRs) were synthesized through a facile hydrothermal method and showed significant enhancement in photocatalytic activity, especially with 5 wt% Gd doping which improved the separation of photogenerated electron-hole pairs. Recycling test confirmed the stability of the photocatalyst after three cycles, making Gd@WO3 NRs a superior catalyst for reducing organic pollutants.

Improved acetone gas sensing performance based on optimization of a transition metal doped WO3 system at room temperature

Mingyu Pi et al.

Summary: This study proposes an efficient material system optimization strategy by doping transition metals into WO3 to enhance acetone gas sensing performance, with Ni:WO3 showing higher sensitivity to acetone. By further optimizing the doping ratio, 3%Ni:WO3 was found to have the best response-recovery speed and target gas selectivity for detecting acetone at room temperature.

UV-light activated APTES modified WO3-x nanowires sensitive to ethanol and nitrogen dioxide

M. Tomic et al.

Summary: The (3-aminopropyl)triethoxysilane modified tungsten oxide nanowires sensors exhibit high sensitivity towards ethanol and nitrogen dioxide under UV-irradiation at room temperature. The sensors also show improved selectivity to nitrogen dioxide and ethanol, with approximately 17 and 20 times more sensitivity compared to non-modified sensors. The results are attributed to the reactive amino group facilitating chemical interaction and electron transfer under UV-light excitation.

Facile synthesis of ZnO-SnO2 hetero-structured nanowires for high-performance NO2 sensing application

Sikai Zhao et al.

Summary: ZnO-SnO2 hetero-structured nanowires were fabricated by growing SnO2 nanoparticles on ZnO nanowires, showing improved NO2 sensing properties with the highest response at a Sn/Zn atomic ratio of 5% and operating temperature of 150 degrees C. These hetero-structured nanowires also exhibited faster response/recovery rate and better NO2 selectivity compared to pristine ZnO nanowires, with the performance difference explained by surface depletion and potential barrier control models.

Novel Christmas Branched Like NiO/NiWO4/WO3 (p-p-n) Nanowire Heterostructures for Chemical Sensing

Navpreet Kaur et al.

Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

MoS2/WO3 Nanosheets for Detection of Ammonia

Sukhwinder Singh et al.

Summary: This article presents a highly sensitive and selective chemiresistive ammonia sensor based on a p-MoS2/n-WO3 heterojunction, showing enhanced performance compared to individual MoS2 and WO3 sensors. The device demonstrates excellent response-recovery features and selectivity towards ammonia, with the capability to detect ammonia down to 1 ppm. The experimental results are further supported by density functional theory (DFT) simulation to understand the sensing mechanism and charge transfer dynamics.
