2019年9月1日 · Here, we report a facile silylation reaction for efficient stabilizing the MXene against structural degradation due to spontaneous oxidation and improved surface properties with adjustable hydrophilicity. (3-Aminopropyl)triethoxysilane functioned MXene (APTES-MXene) was chosen as the model to evaluate the stability and surface property changes.

2017年3月24日 · Figure 2a presents the UV–vis-NIR absorption spectra (300–1300 nm) of MXene and CNT aqueous suspensions with the same mass concentration of 0.1 mg/mL. As can be seen, CNT absorbs broad spectrum from 300 to 1300 nm without any distinct absorption peak while MXene exhibits a basic absorption much higher than CNT material with an absorption ...

We report on one-step hybridization of silver, gold and palladium nanoparticles from solution onto exfoliated two-dimensional (2D) Ti3C2 titanium carbide (MXene) nanosheets. The produced hybrid...

2021年3月16日 · The UV–vis absorption spectrum is widely used to analyze the degree of oxidation in MXenes because each MXene has its own characteristic absorption peaks at a certain wavelength . Kim et al. investigated the UV–vis spectra of the Ti 3 C 2 T x MXene dispersion in water that was stored for one month (Fig. 2i).

8、紫外-可见漫反射光谱（UV-vis DRS）： 通过UV-vis DRS对样品的光学性质进行评估。Ti3C2 MXene和MXene@Pt样品在250-800 nm范围内表现出强烈的光吸收，并且没有明显的吸收边缘，表明了MXene@Pt复合物独特的光收集和没有带隙的金属特性。

2024年12月3日 · To maximize photothermal performance, MXene metamaterials (m-MXenes) are developed with a superlattice with alternating MXene and organic layers, reducing RI and inducing multiple light...

2024年12月27日 · Here we introduce in situ UV-visible (UV-Vis) spectroscopy method to distinguish battery-type, pseudocapacitive and elec. double-layer charge storage processes. On the basis of Ti3C2Tx MXene in aq. acidic and neutral electrolytes, and lithium titanium oxide in an org. electrolyte, we found a correlation between the evolution of UV-Vis spectra ...

6 天之前 · This MMRSA obtained 95.87% and 95.74% absorptance over the VIS and UV ranges, which correspond to results in the UV to FIR range. MMRSA’s NIR, MIR, and FIR results were 97.13%, 94.45%, & 91.39% ...

Fig. 7 a depicts the comparative UV–vis absorption profiles of the raw MXene, dispersed MXene in nitric acid, and the hydrothermally treated N-MQDs before dialysis (N-MQDS-B). The influence of pH on the absorption peak of N-MQDs is investigated in Fig. 7 b, suggesting potential interactions between the functional groups of N-MQDs and the ...

2025年3月25日 · Phosphorous Doped Ti 3 C 2 T x MXene/Carbon Foam Hybrid Aerogel as a Versatile Platform for Industrial Waste Treatment, ... Subsequently, 2 mL samples were taken from the dye solution at an interval of 3 min and immediately analyzed using a UV-vis absorption spectrophotometer. For the organic dyes, the concentration was maintained at 10 mg/L. ...
