Quick response and high sensitivity are equally important for the practical application of gas sensors. In this study, we introduced polyoxometalates (POMs) into a classical ternary metal oxide CuBi2O4 first time by convenient electrospinning prepared group heater-type sensors using CuBi2O4/PW12 composite nanofibers. The sensor performances to formaldehyde were explored. results proved that gas-sensing (PW12 = H3PW12O40·xH2O) 100 ppm was increased 6.68, which 3.92 times greater than sensing capacity pure sensor. Simultaneously, exhibited highly rapid response/recovery only 1/2 s, is significantly faster reported in past literature. cause improvement performance assessed via mechanism it found introduction PW12 contributed its enhanced performance. It PW12, as an electron acceptor, carrier mobility reduced electron–hole recombination, thus contributing properties. Moreover, other parameters such selectivity, humidity resistance, repeatability, long-term stability investigated. Hence, study literature on development polyoxometalates-based

ZnO/MOx (M = FeIII, CoII,III, NiII, SnIV, InIII, GaIII; [M]/([Zn] + [M]) 15 mol%) nanofiber heterostructures were obtained by co-electrospinning and characterized X-ray diffraction, scanning electron microscopy fluorescence spectroscopy. The sensor properties of ZnO nanofibers studied toward reducing gases CO (20 ppm), methanol acetone oxidizing gas NO2 (1 ppm) in dry air. It was demonstrated that the temperature maximum response is primarily influenced binding energy chemisorbed oxygen with surface modifier's oxides. When detecting NO2, high sensitivity at a low measurement can be achieved concentration free electrons near-surface layer zinc oxide grains, which determined band bending interface difference work function MOx.

In this study, CoFe bimetallic phosphide microflowers electrocatalyst are supported on nickel foam. The composition and phosphating can effectively improve the OER HER performances realize optimized overall water splitting performance. It requires only an overpotential of 68 mV in 1 M KOH to reach a current density 10 mA·cm−2 for 227 OER. When optimal sample (CoFe10%-P/NF) was used splitting, low cell voltage 1.610 V is required at alkaline solution. stability also good. This study provides feasible proposals splitting.

Both covalent organic frameworks (COFs) and polyoxometalates (POMs) show excellent properties application potential in many fields, thus receiving widespread attention. In recent years, COF-POM hybrid materials were prepared by combining COFs POMs through physical or chemical methods. hybrids have shown high performance such as catalysis, sensing, energy storage, biomedicine. this review, we introduced the preparation strategy of detail. We believe that combination will provide more abundant functions broad prospects.
