2D TiVCT_x layered nanosheets grown on nickel foam as highly efficient electrocatalysts for the hydrogen evolution reaction

Abstract

The TiVCTx MXene was obtained by etching and peeling methods, and the TiVCTx@NF hybrid electrode material was obtained by the deposition method. The electrochemical performance was evaluated using a variety of characterization methods.

TiVCTX MXene/Graphene Nanosheet-Based Aerogels for Removal of Organic Contaminants from Wastewater

“…The TiVAlC precursor exhibits diffraction peaks at 13.20, 34.69, 40.28, 54.16, and 62.17°, which correspond to the (002), (100), (103), (106), and (110) planes of the standard MAX phase of TiVAlC, respectively. Following the etching process, most of the characteristic peaks of TiVAlC disappeared and the resulting TiVCT X nanosheets exhibit a single peak at 8.12°, representing the (002) plane, which is a typical feature of MXene materials. , This peak also confirms the complete elimination of the Al atomic layer from the TiVAlC precursor. Additionally, the (002) peak of TiVCT X nanosheets shifts from 13.20° in TiVAlC to a lower angle of 8.12°, indicating the successful exfoliation of TiVCT X nanosheets with a larger interplanar spacing, , as depicted in Figure b.…”

Recent advances in the role of MXene based hybrid architectures as electrocatalysts for water splitting

“…Hydrogen fuel as green energy has emerged as a promising solution as an alternative energy source. [4][5][6][7][8][9] The production of hydrogen by electrochemical water splitting has several advantages, including faster reaction time, high purity of the hydrogen produced, and zero greenhouse gas emissions compared to other methods. 10,14 The electrochemical water splitting reaction comprises two halfcell reactions, namely the oxygen evolution reaction (OER) that occurs at the anode and the hydrogen evolution reaction (HER) that takes place at the cathode represented by the following equations.…”

MXene-Based Chemo-Sensors and Other Sensing Devices

“…The family of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides called MXenes has significantly grown since the first report of the synthesis of Ti 3 C 2 in 2011 [ 1 ]. In recent years, MXenes have greatly impacted many fields, including energy storage [ 2 , 3 ], electronics [ 4 , 5 ], biomedicine, catalysis [ 6 , 7 ], environmental technologies, and many other technological areas. This widespread attention arises from the exceptional set of properties attributed to MXenes, which include superior mechanical strength and flexibility [ 8 ], liquid-phase processability [ 9 ], tunable surface functionality [ 10 ], high electrical conductivity [ 11 ], and the ability to customize their properties.…”
