A new strategy to one-step construct polyoxometalate/semiconductor one-dimensional tandem heterojunctions toward optimized conductometric sensing performances of ethanol gas

Jinmei Tian et al.

Summary: In this study, one-dimensional tandem heterojunctions of SnO2 @POMs@WO3 nanofibers were prepared using coaxial electrospinning, and the gas sensing performance was significantly improved compared to SnO2 @WO3 nanofibers. The optimized response to 100 ppm ethanol reached 8.8, providing a new strategy for developing high-performance gas sensors through synthesizing one-dimensional tandem heterojunctions and introducing POMs.

One-step fabrication of TiO2@polyoxometalates@?-Fe2O3 one-dimensional tandem heterojunctions for conductometric acetone sensors

Yuting Wang et al.

Summary: This study presents a new strategy to construct TiO2 @POMs@ alpha-Fe2O3 one-dimensional tandem heterojunctions materials through one-step coaxial electrospinning. Three series of TiO2 @POMs@ alpha-Fe2O3 core-middle-shell nanoribbons with different Keggin-type POMs were synthesized. Gas sensing performances of the nanoribbons were investigated, showing significantly improved sensitivity and selectivity to acetone. The enhancement can be attributed to the addition of POMs electron acceptors, the construction of tandem heterojunctions, and the one-dimensional nano-structure.

Phosphorus-doped porous perovskite LaFe1-xPxO3-δ nanosheets with rich surface oxygen vacancies for ppb level acetone sensing at low temperature

Wenbo Qin et al.

Summary: In this study, P-doped perovskite LaFe1-xPxO3-delta with abundant Ov defects were prepared and utilized as sensors for acetone detection. The LaFe0.99P0.01O3-delta sensor exhibited excellent gas-sensitive performance, with nearly twofold improvement in response value and a detection limit at the ppb level. Electron paramagnetic resonance and X-ray photoelectron spectroscopy confirmed the strong correlation between the sensing characteristics and the Ov defects. Theoretical analysis revealed that P doping induced Ov defects and modulated the energy levels of the material, enhancing chemisorbed oxygen species and intermolecular interactions.

Polyoxometalate Interlayered Zinc-Metallophthalocyanine Molecular Layer Sandwich as Photocoupled Electrocatalytic CO2 Reduction Catalyst

Haozhou Yang et al.

Summary: A general synthetic method for zinc-metallophthalocyanine (MPc) molecular layer/polyoxometalate (POM) sandwich lamellar material was developed in this study, which improved the performance of CO2 reduction. The incorporation of POM prevented aggregation of MPc molecular layers and favored the exposure of active sites. The molecular layer sandwich catalyst showed superior CO2 reduction activity and achieved high CO Faradaic efficiency under dark and light conditions, with enhanced catalytic performance under external light field.
