Synthesis of two-dimensional Ti3C2Tx MXene using HCl+LiF etchant . . . Herein, enhanced exfoliation and large-scale delamination of two-dimensional (2D) Ti3 C 2 T x MXene using etchant of HCl + LiF, instead of HF, in which both etching and intercalation were achieved in exfoliation process, were thoroughly investigated with the focus on the effects of two critical factors, reaction temperature and washing solution
Pristine MXene: In Situ XRD Study of MAX Phase Etching with HCl+LiF . . . Here the first time-resolved in situ synchrotron radiation X-ray Diffraction study of MXene synthesis performed using a plastic capillary-size reaction cell directly in HF solution is reported This study provides the first report on the structure of “pristine MXene” formed by Ti3AlC2 etching with LiF HCl
Comparative Study of Ti3C2Tx MXene Synthesized via HF and LiF-HCl . . . 2 2 In Situ HF Etching In the indirect etching process, 20 ml of hydrochloric acid (HCl) and 2 07 g of lithium fluoride (LiF) were used to prepare a solution at room temperature and stirred for 30 min After that, 0 5 g of Ti 3 AlC 2 was added to the solution pinch by pinch until its bubbles settled down and stirred continuously at 50 °C for 24 h The resulting product was washed with
Critical Analysis of MXene Production with In‐Situ HF Forming Agents . . . The main obstacle towards their massive implementation is the synthesis requiring the direct use of HF as etching agent The development of alternative synthetic routes exploiting in-situ forming HF agents is the main strategies to overcome this limitation
Pristine MXene: In Situ XRD Study of MAX Phase Etching with HCl+LiF . . . Here the first time-resolved in situ synchrotron radiation X-ray Diffraction study of MXene synthesis performed using a plastic capillary-size reaction cell directly in HF solution is reported This study provides the first report on the structure of “pristine MXene” formed by Ti3AlC2 etching with LiF+HCl
Environment-friendly synthesis of Ti3C2TX MXene by etching and galvanic . . . Abstract Although MXene is acknowledged as next generation two-dimensional (2D) nanomaterials, in general, MXene has been obtained by using hazardous and corrosive etching agents such as HF and HCl Therefore, in the present study, we report on the environment-friendly synthesis of 2D Ti 3 C 2 T X MXene using weak acid H 3 PO 4 as etchant
Chemical Exfoliation and Delamination Methods of MXenes | part of MXene . . . Because of their milder and safer than HF, in‐situ HF‐forming etching methods are widely studied firstly, such as fluoride salts (e g , LiF, KF, and NH 4 F) in HCl or H 2 SO 4 and hydrothermal route with low toxicity etching agents (e g , NaBF 4 in HCl) However, the releases of volatile HF gas formed during mixing are still risky
