“…Apart from the carbon based and metal nanomaterials, metal oxides (MOX) attracted great attention, due to their chemical characteristics and functional properties [ 3 , 4 , 5 ], for the development of chemical sensors [ 6 , 7 ] applied to achieve a safer working environment. In compliance with government regulations such as Control of Substances Hazardous to Health (COSHH) and Occupational Safety and Health Administration (OSHA) regulations, MOX based sensors have been recently adopted to efficiently reveal the presence of toxic and combustible gases (i.e., hydrogen sulfide, carbon monoxide) to withstand high humidity and temperature.…”

Pure, mixed and doped metal oxides (MOX) have attracted great interest for the development of electrical and electrochemical sensors since they are cheaper, faster, easier to operate and capable of online analysis and real-time identification. This review focuses on highly sensitive chemoresistive type sensors based on doped-SnO2, RhO, ZnO-Ca, Smx-CoFe2−xO4 semiconductors used to detect toxic gases (H2, CO, NO2) and volatile organic compounds (VOCs) (e.g., acetone, ethanol) in monitoring of gaseous markers in the breath of patients with specific pathologies and for environmental pollution control. Interesting results about the monitoring of biochemical substances as dopamine, epinephrine, serotonin and glucose have been also reported using electrochemical sensors based on hybrid MOX nanocomposite modified glassy carbon and screen-printed carbon electrodes. The fundamental sensing mechanisms and commercial limitations of the MOX-based electrical and electrochemical sensors are discussed providing research directions to bridge the existing gap between new sensing concepts and real-world analytical applications.

“…Among ZnO nanomaterials, porous nanostructures with nanoscale thicknesses have received special attention due to their large specific surface area, which can enhance their performance in numerous applications [ 44 , 45 , 46 , 47 , 48 , 49 ]. Porous ZnO nanostructures can be obtained by the thermal decomposition of layered zinc hydroxide (LZH) materials [ 20 ].…”

The degradation of organic pollutants in wastewaters assisted by oxide semiconductor nanostructures has been the focus of many research groups over the last decades, along with the synthesis of these nanomaterials by simple, eco-friendly, fast, and cost-effective processes. In this work, porous zinc oxide (ZnO) nanostructures were successfully synthesized via a microwave hydrothermal process. A layered zinc hydroxide carbonate (LZHC) precursor was obtained after 15 min of synthesis and submitted to different calcination temperatures to convert it into porous ZnO nanostructures. The influence of the calcination temperature (300, 500, and 700 °C) on the morphological, structural, and optical properties of the ZnO nanostructureswas investigated. All ZnO samples were tested as photocatalysts in the degradation of rhodamine B (RhB) under UV irradiation and natural sunlight. All samples showed enhanced photocatalytic activity under both light sources, with RhB being practically degraded within 60 min in both situations. The porous ZnO obtained at 700 °C showed the greatest photocatalytic activity due to its high crystallinity, with a degradation rate of 0.091 and 0.084 min−1 for UV light and sunlight, respectively. These results are a very important step towards the use of oxide semiconductors in the degradation of water pollutants mediated by natural sunlight.

“…In addition, another critical issue existing in alloy/carbon composite is the weak interfacial interaction between carbon and alloy, which may lead to the separation of alloy and carbon matrix and electrochemical performance deterioration . Recently, constructing metal/metal oxide composite as anode for LIBs has been put forward and an enhanced structure stability as well as longer cycle performance was observed, benefiting from the strong metal‐oxide bond …”

Rapid progress of lithium‐ion batteries (LIBs) highly relies on high‐performance electrode materials. Herein, a novel nanocomposite of CoSn alloy with a multishell layer structure confined in 3D porous carbon is constructed through a facile freeze drying and annealing treatment method. The skillful design effectively relieves the volume expansion of the Sn‐based alloy and enhances the combination between CoSn and carbon. Profiting from the synergistic effect of the multibuffer structure alloy and cross‐linked porous carbon, CoSn@SnOx/CoOx@C displays high capacity (912.6 mA h g−1 after 100 cycles at 0.1 A g−1) and excellent cycling stability (almost no capacity decay at 10 A g−1 after 1000 cycles) when used as anode for LIBs. The presence of Sn–O/Co–O bond makes the nanoalloy tightly pinned on the carbon substance and the structure stability of electrode material is improved significantly. Furthermore, the porous carbon with plentiful defects offers abundant room for the volume expansion of Sn and ensures fast transport of electrons/ions. Cyclic voltammogram (CV) curves under different scan rates reveal that the charge storage of the nanocomposite is controlled by pseudocapacitive and ion‐diffusion mechanisms. This facile fabrication strategy and unique structure design can be extended to other composite materials for energy storage devices.
