Enhanced photocatalytic activity of accordion-like layered Ti3C2 (MXene) coupled with Fe-modified decahedral anatase particles exposing {1 0 1} and {0 0 1} facets

Metal (Mo, W, Ti) Carbide Catalysts: Synthesis and Application as Alternative Catalysts for Dry Reforming of Hydrocarbons—A Review

“…MXene compounds are gaining importance due to their metal-like conductive properties, thermal and chemical stability, and the ability to manipulate properties through simple and effective modification of terminal groups [162,163]. Their unique properties allow for application in various branches of science: energy storage [163,164], electrocatalysis [165,166], photocatalysis [167,168], and heterogeneous catalysis [23,[164][165][166]169].…”

“…Recently, an increasing number of research reports on modified metal carbides from the MXene group to improve catalytic [169,180], conducting [186,187], photocatalytic [167,182], and optical response properties [167,182] have been published. He et al [187] synthesized Ni 1.5 Co 1.5 S 4 @Ti 3 C 2 nanocomposites for high-performance supercapacitors.…”

“…The upgraded properties of metal/metal oxide/MXene nanocomposites were also observed for Fe/TiO 2 /Ti 3 C 2 photocatalysts. Grzegórska et al [167] obtained TiO 2 /Ti 3 C 2 nanocomposites by hydrothermal treatment of the Ti 3 C 2 MXene. As a result, decahedral TiO 2 of exposed {101} and {001} facets created a highly efficient connection in the photocatalytic degradation of pharmaceuticals.…”

Microstructure and opto-electronic EFFECTS IN MXenes spincoated from polar aprotic solvents on ito

“…It is worth noting that the typical Raman peaks of TiO2 (Eg at 150 cm -1 ; B1g at 400 cm -1 , A1g at 600cm -1 ) are missing from these films, probably due to its relatively low content in the films. [11] Figure 2 shows the Raman mapping of the film microstructure corresponding to the A1g vibrations in the MXene flake region. The size of the flakes or particles corresponding to the Raman vibrations are well correlated with the lateral sizes of the protrusions observed in the AFM topography of the MXene films.…”

A simple preparation method of in situ oxidized titanium carbide MXene for photocatalytic degradation of catechol

“…[29][30][31] Recently, as a new ''Star'' series of the two-dimensional material, MXs (transition metal carbides and nitrides, represented by a general formula of M n+1 X n T x , where M, X, and T refer to transition metal, an X group element group, and C or N element, respectively) have comparable conductivity, abundant functional groups and excellent physical and chemical properties with graphene in photocatalysis, making them extensively used in supercapacitors, batteries, catalysis, sensors, and other fields. [32][33][34][35][36][37] Among them, MX Ti 3 C 2 has attracted great attention. 29,30,[38][39][40] MX Ti 3 C 2 can be easily compounded with semiconductors to form a Schottky junction, 41 which can efficiently restrain the combination of photogenerated carriers and greatly improve the photocatalytic efficiency.…”
