Recent advance in two-dimensional MXenes: New horizons in flexible batteries and supercapacitors technologies

Recent Progress in Emerging Novel MXenes Based Materials and their Fascinating Sensing Applications

“…[ 292,293 ] HF in varied concentrations was the initial etchant applied to etch Ti 3 AlC 2 MAX phase. [ 9–91,293,294 ] Ghidiu and his colleagues [ 295 ] demonstrated in 2014 that etching the parent ternary compounds by means of a combination of HCl and LiF is also achievable. The HF is still generated by in situ mean in this situation.…”

“…To achieve high‐performance sensors new novel low‐dimensional active sensing materials are extremely required for the future nanotechnological world. [ 9–91 ] As a result, low dimensional materials, for example, 2D materials [ 20,30,40,43–45,47,50,51,56,83,92–98 ] are studied, which are deliberate broadly for the past few decades; starting with breakthrough of unusual physical and electrochemical properties of single‐atomic layer carbons, called graphene. [ 30,40,45,56,96,99 ]…”

Recent advances in MXenes: a future of nanotechnologies

“…Low electrical noise and high signal throughput are often two essential issues in the development of sensitive gas sensors. 1–7,9,12,14–18,26,29,30,35,52,55,95,118,119,462–469 This is likely if the sensing platform can handle both high conduction and a large number of active spots for interfacial interactions. Traditional materials, such as graphene, metal oxides, and black phosphorous (PB), exhibit a trade-off relationship, classifying them as suitable but not ideal for sensing applications.…”

“…M n +1 X n T x ( n = 1 to 4) is a common formula for 2D MXene NMs, where M indicates transition metals (TMs) 3,5,6,13,20,49–80 and X indicates carbon or nitrogen, respectively 1,7–10,15,16,18,23,25,35,81–126 . Also, T x (where x varies) denotes single or mixed termination groups (for example, T = S, O, NH, F, Cl, Br, Te, OH, Se), as shown in Fig.…”

Recent major advances and challenges in the emerging graphene-based nanomaterials in electrocatalytic fuel cell technology

“…The quality and performance of the produced graphene cost and its processability should be considered when determining the optimal substrate. 5–7,10–13,15–17,43,45,52,55,56,60,63,67,69,71,73,548–609…”
