“…Meanwhile, Wang et al [ 11 ] reported that an urchin-like CuO nanostructure produced a remarkable humidity sensing response due to the capillary condensation process, facilitated by the gap existing between the spine structures. Similar results have also been reported for devices prepared using hollow balls [ 12 ], nanosheets [ 13 ], nanofibers [ 14 ], nanoflakes [ 15 ], nanotubes [ 16 ], and other structures.…”

Unique three-dimensional (3D) titanium dioxide (TiO2) nanoflowers (TFNA) have shown great potential for humidity sensing applications, due to their large surface area-to-volume ratio and high hydrophilicity. The formation of a composite with other materials could further enhance the performance of this material. In this work, the effect of different types of composites on the performance of a TNFA-based humidity sensor was examined. NiO, ZnO, rGO, and PVDF have been explored as possible composite pairing candidates with TiO2 nanoflowers, which were prepared via a modified solution immersion method. The properties of the composites were examined using field emission electron spectroscopy (FESEM), X-ray diffractometry (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), current-voltage (I-V) analysis, Hall effect measurement, and contact angle measurement. The performance of the humidity sensor was assessed using a humidity sensor measurement system inside a humidity-controlled chamber. Based on the result, the combination of TiO2 with rGO produced the highest sensor response at 39,590%. The achievement is attributed to the increase in the electrical conductivity, hydrophilicity, and specific surface area of the composite.

As the fossil fuels are running out, the world is advancing toward renewable energy sources and related energy storage technologies. Metal−air batteries have received significant prominence due to their high energy density compared to conventional batteries and fuel cells. Particularly, lithium−air battery has garnered tremendous attention owing to its highest theoretical energy density alongside a large cell capacity. However, technical challenges pertaining to the cathode such as cell voltage drop, carbon electrode corrosion, detrimental side reactions, electrode pore clogging, etc., still persist and hinder their commercial success. So, to improve their overall performance and make them a practical success, various cathode materials are being investigated by researchers around the globe. Nanoengineering of two-dimensional materials is one such subject under extensive investigation, where MXenes have recently emerged as strong candidates with their unique properties such as high hydrophilicity, large interlayer spacing, and high mechanical stability. MXenes with high electrical conductivity and catalytic activity possess a huge potential for applications in energy storage. Over the past few years, more than 30 MXenes with different chemistries have been synthesized for various applications. Yet, titanium carbide MXene (Ti 3 C 2 T x ) remains as the most studied MXene, mainly, but not exclusively, for its high electrical conductivity, which makes it a suitable choice for electrode material. This review presents an overview of MXene, its syntheses, and an up-to-date summary from the literature focused on the potential use of TiC MXenes as cathodes in Li−air batteries.
