“…Unfortunately, the disadvantages of Al, such as its tendency to passivate easily and its high redox potential, have posed challenges for its further development. For instance, Al 3+ has been regarded as a notably poor migrant in solids due to its substantial electrostatic interaction with surrounding anionic structures and the low polarizability of the ion caused by a small Al 3+ ionic radius. , On the other hand, Zn metal possesses numerous benefits including a low redox potential (−0.76 vs SHE), environmental compatibility, and safety. Zn metal can be used as the ion-storage layer for the EC layer of ECDs .…”

The interface between the electrochromic (EC) electrode and ionic conductor is crucial for high-performance and extraordinarily stable EC devices (ECDs). Herein, the effect of the ALD−AZO interfacial layer on the performance of the WO 3 thin film was examined, revealing that an introduction of the ALD−AZO interfacial layer to the Al 3+ -based complementary ECDs can lead to improved EC performance and stability, such as an extraordinary cyclability of more than 20,000 cycles, an outstanding coloration efficiency of 109.69 cm 2 C −1 , and a maximum transmittance modulation of 63.44%@633 nm. The probable explanation is that the introduced ALD−AZO interfacial layer can effectively regulate the band gap of WO 3 , promote the electron transport process, and induce the formation of a robust solid electrolyte interphase to protect the electrode during cycling. These findings offer valuable insights for enhancing the EC performance of the EC thin films and new space for the construction of advanced multivalent Al 3+ -based ECDs.

“…Therefore, there is a strong demand in this regard for developing gas sensors with excellent sensing performance and practical application in human health protection and air monitoring. To meet this requirement, various types of gas sensors such as chemiresistive gas sensors, field-effect transistors, solid-state electrochemical sensors and optical gas sensors have been well developed. − Among them, chemiresistive gas sensors have become one of the most widely used gas sensors for commercialization due to their simple production, low cost, sensing material requirements of gram grade, and wide selection of sensing materials …”

Polyoxometalates (POMs) are a series of molecular metal compounds based on W and Mo elements, exhibiting excellent physical and chemical properties. POMs have been widely used in the fields of photoelectric materials, catalytic materials, and coordination chemistry. In recent years, POMs have emerged in the field of chemiresistive gas sensors. They can work as electron acceptors and improve the gas-sensing performance of traditional sensing materials by means of capturing electrons from semiconductors, separating electrons produced by light excitation or thermal excitation and delaying the recombination of electrons and holes. So far, the highest sensing sensitivity response of POMs-based chemiresistive gas sensor is 231 to 1 ppm NO2 gas. In this review, an overview is investigated about how POMs have evolved as sensing materials in gas sensors. First, some POMs and POMs-based sensing materials in recent years are introduced and classified. After that, brief analyses for each kind of sensing materials are provided. Then we compare the reported POMs-based sensors in different sensing parameters. Finally, the future outlooks are discussed on the basis of the current developments. This work is the first comprehensive overview of POMs-based chemiresistive gas sensors. This work can provide valuable information for developing high-performance POMs-based gas sensors.

Anthropogenic air and water pollution are two of the world's most serious public health threats, causing around 9 million fatalities each year. Accordingly, CuO, ZnO, and CuO@ZnO core/shell structures were optimized utilizing the time-dependent density functional theory (TD-DFT) method to study the effect of CuO@ZnO core/shell on the sensitivity of carboxymethyl cellulose sodium (CMC). Absorption spectra and optical band gap (Eg) have been investigated utilizing the TD-DFT method. The calculated Eg values for CuO and ZnO equal 1.23 and 3.29 eV, respectively, which agree well with those reported in the literature. The effects of H2S gas and methylene blue dye (MB) adsorption on the electronic characteristics of dimer CMC /CuO@ZnO structures were investigated in terms of TDM, HOMO/LUMO energy, and molecular electrostatic potential (MESP). The TDM in dimer CMC/CuO@ZnO structure was increased to 72.152 and 67.606 Debye, while ΔE was reduced by 6.42% and 82.57% due to the adsorption of H2S and MB dye, respectively. This means that it has a faster response to MB than to H2S. Additionally, MESP confirms the increased reactivity of dimer CMC/CuO@ZnO due to the adsorption process. As a result, dimer CMC/CuO@ZnO structures appear to be attractive candidates for H2S and MB dye sensing applications.
