“…Afterward, in the step of replacement, the – F terminal groups may be substituted by – O terminal groups. The O-terminated Ti 3 C 2 MXene can exhibit higher active surface areas as a result of the O-substituted surface, resulting in improved electrochemical performance . The surface terminal groups have an effect on the Ti 3 C 2 T x properties that are possibly examined through transmission electron microscopy (TEM), neutron scattering, and nuclear magnetic resonance (NMR) techniques.…”

Construction of an S-Scheme Heterojunction with Oxygen-Vacancy-Rich Trimetallic CoAlLa-LDH Anchored on Titania-Sandwiched Ti3C2 Multilayers for Boosting Photocatalytic CO2 Reduction under Visible Light

“…Apart from noble metals, the newly discovered MXene materials have been utilized with LDH to reduce the recombination, which may result in enhanced photocatalytic activity toward CO 2 reduction. Shi et al 64 through a hydrothermal process constructed a 3D NiAl-LDH/Ti 3 C 2 hierarchical nanocomposite through in situ loading of Ti 3 C 2 on the NiAl-LDH framework. The 3D structure of the composite with a high specific surface area caused beneficial absorption and utilization of photons.…”

Enhanced photocatalytic activities of a hierarchical ZnO/V2C MXene hybrid with a close coupling heterojunction for the degradation of methyl orange, phenol and methylene blue dye

“…13,14 To solve these shortcomings, the co-catalyst modification of ZnO photocatalysts is considered to be an effective method to improve the photocatalytic performance by promoting the effective separation of photo-induced charges. [15][16][17][18] The co-catalyst normally includes carbon based materials (carbon nanotubes, 19 graphene, 20 and C 3 N 4 to significantly enhance the photocatalytic performance due to its unique morphology with exposed metal sites and good electrical conductivity. [31][32][33][34] These MXene materials usually exhibit a strong interface coupling effect with these photocatalysts, leading to a fast charge transfer kinetics, 35 thus effectively enhancing the photocatalytic performance.…”

“…To solve these shortcomings, the co-catalyst modification of ZnO photocatalysts is considered to be an effective method to improve the photocatalytic performance by promoting the effective separation of photo-induced charges. 15–18 The co-catalyst normally includes carbon based materials (carbon nanotubes, 19 graphene, 20 and C 3 N 4 21 ), metal nanoparticles 22 and others, 23–26 which can be used to reduce the recombination ratio of photoinduced electron–hole pairs on ZnO and thus enhance the photocatalytic efficiency of ZnO. Recently, a new type of 2D material named MXene, which is usually obtained by exfoliation of M n +1 AX n materials, was employed as a co-catalyst on some photocatalysts including TiO 2 , 27 Bi 2 WO 6 , 28 BiOBr, 29 and CdS 30 to significantly enhance the photocatalytic performance due to its unique morphology with exposed metal sites and good electrical conductivity.…”
