“…[ 83 ] However, some problems are necessary to be considered, on the one hand, HF is strong toxic and corrosive. [ 105 ] The gained MXene has fallen into the surface chemical uncontrollable condition. On the other hand, this process is more applicable to the MAX phase that can react with hydrogen fluoride, especially the MAX phase where A is an aluminum element.…”

Moreover, a study from the World Health Organization (WHO) emphasized that death due to heart diseases and diabetes is still an upward trend and expected to be the first and seventh leading causes of death, respectively, by 2030. [16] Therefore, early diagnosis and treatment is urgently on demand. [12,17] A variety of human health-detection devices, intelligent wearable devices, and medical intelligent devices as efficient strategies have been emerging and making a big difference in daily life, [18][19][20][21][22][23] making it higher efficient, more accurate, more timely than traditional detection techniquesIn the meanwhile, sensors, as a vital component in intelligent detection devices quickly bloom to meet the requirement of high sensitivity, wide detection range, and stable response sensing capability. Sensors work through transforming external stimulus including biological, chemical, and physical changes into electrical signals changes. According to their respective work mechanism, sensors can be classified into the following several categories: piezoresistive, [24][25][26] piezoelectric, [27][28][29] frictional, [30] and capacitive. [31][32][33][34] Among them, piezoresistive sensors have attracted extensive concern for its simple structure, low cost, and easy signal acquisition, further being applied to the field of wearable detection devices. [35,36] It works by transforming external stimulus into visual electrical signals, and the change of resistance is generated by microscopic deformations of its own structure. [37][38][39][40] From sensors functional point of view, sensors can also be divided into strain sensors, [39,[41][42][43][44] stress sensors, [45,46] humidity sensors, [47] gas sensors, [41,48,49] temperature sensors, [50] and so on. On the present overall view, the key issue focuses on how to realize ideal sensors compatible with high sensitivity, wide detection range, ultralow response time, ultralow detection limitation, superb linearity, and cyclic stability. [51][52][53][54][55][56][57][58][59][60] What is noteworthy is that conductive materials interacting with other substances have been considered as an extremely efficient strategy to realize high sensing performance, being able to give out fast response reacting to outer tiny changes. Currently, aiming to endow sensors superb sensitivity and wide sensing range, flexible substrates for sensors commonly choose polydimethylsiloxane (PDMS), hydrogenated styrene-butadiene block copolymer (SEBS), and silicone rubber and other high elastic polymer materials. [37,57,61,62] Then, the composite sensor is fabricated successfully by different preparation techniques including With the advent of the era of intelligent manufacturing, sensors, with various detection objects, have set off a wave of enthusiasm and reached new heights in medical treatment, intelligent industry, daily life, and so on. MXene, as an emerging family of 2D transition metal carbides/nitrides, possesses impressive electrical conductivity, outstanding structural controllability, ...

“…The combination of MXene and graphene can effectively prevent self‐stacking between graphene and the MXene sheets, which could increase the available specific surface area, accelerate the diffusion of electrolyte ions and enhance the properties of the materials . Moreover, the combination of the electric double layer effects of graphene and the pseudocapacitance properties of MXene will further improve the electrochemical energy storage of the composite.…”

Novel nanomaterials and advanced nanotechnology continuously push forwardt he rapid development of sustainable energy conversion and storage equipment. An emerging family of two-dimensional transition-metal carbides, nitrides and carbonitrides, also known as MXenes, have attracted increasing attention and in depth investigation. Benefitting from their unique intrinsic properties, MXenes have attracted significant attention and they have been considered as promising candidate materials for the development of environmentally friendly energy resources. Al arge number of studies show that MXenes have great potential in energy conversiona nd storagef ields. Despite of their exceptional properties, MXenes also have some inher-ent characteristics, such as low capacities and unstabler etention performances, which severely hinder their prospect applicationsi ne nergy conversion and storage fields. In this Minireview,t he latest progress on MXenes and their hybrid composites with small molecules, polymers, carbon or metal ions, and their applicationsinenergy conversionand storage fields is highlighted, including their use in different types of batteries, supercapacitors, hydrogen/oxygene volution reactions, electromagnetic interference absorption/shielding and solar steam generation.

“…Generally, Ti 3 C 2 T x -based aerogels are fabricated by hydrothermal method and freezecasting technique to achieve high porosity [6,8]. On one hand, the Ti 3 C 2 T x gelation process in the hydrothermal strategy requires the use of cross-linkers (mostly graphene oxide), which will deteriorate the intrinsic properties of Ti 3 C 2 T x due to their low conductivity and limited capacitance [8][9][10]. Moreover, the heat treatment through the hydrothermal process will inevitably accelerate the oxidation of Ti 3 C 2 T x , limiting its capacity and rate capability [11][12][13].…”

Ti3C2Tx-based aerogels have attracted widespread attention for three-dimensional porous structures, which are promising to realize high-rate energy storage. However, disordered Ti3C2Tx aerogels with highly tortuous porosity fabricated by conventional unidirectional freeze-casting substantially increase ion diffusion lengths and hinder electrolyte ions transport. Herein we demonstrate a new bidirectional ice-templated approach to synthesize porous ordered Ti3C2Tx aerogel with straight and aligned channels, straight and short ion diffusion pathways, leading to better ion accessibility. The aligned Ti3C2Tx aerogel exhibits the high specific capacitance of 345 F g−1 at 20 mV s−1 and rate capability of 52.2% from 10 to 5000 mV s−1. The specific capacitance is insensitive of mass loadings even at 10 mg cm−2 and an excellent power density of 137.3 mW cm–2 is obtained in symmetric supercapacitors. The electrochemical properties of Ti3C2Tx aerogel supercapacitors at sub-zero (to −30 °C) temperatures are reported for the first time. The aligned Ti3C2Tx aerogel delivers temperature-independent rate performance and high capacitance retention (73% at 50 mV s−1 from 25 to −30 °C) due to the unique structure with metallic conductivity.
