“…Since the CB of g-C 3 N 4 (−1.03 eV) has a potential lower than that of TiO 2 (−0.17 eV), the excitated electrons on the g-C 3 N 4 surface can easily shift to the TiO 2 surface through the hetero interface. 42 Finally, these electrons can be captured by the La 3+ with free orbitals. 43 The electrons accumulated on the La 3+ surface can easily be captured by the O 2 dissolved in solution to generate superoxide ·O 2− , and the generated ·O 2− can subsequently be used to degrade RhB.…”

We prepared a new three-dimensional, flower-like La-TiO 2 /g-C 3 N 4 (LaTiCN) heterojunction photocatalyst using a solvothermal method. Analysis and characterization were performed by conducting scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform-infrared spectroscopy, ultraviolet-visible spectrophotometry, and nitrogen adsorption and desorption. The prepared g-C 3 N 4 nanosheets could reach 100 nm in size and covered the TiO 2 surface. A tightly bound interface formed between the g-C 3 N 4 and TiO 2 , speeding up the effective transfer of photo-induced electrons. In addition, the incorporation of La 3+ reduced the electron-hole recombination efficiency. Consequently, the prepared La-TiO 2 /g-C 3 N 4 composite material exhibited better visible-light catalytic activity than pure TiO 2 .

“…The design and construction of TiO 2 /g-C 3 N 4 hybrid photocatalysts have attracted much attention, as they have been recognized as an effective material for various environmental and energy applications [ 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 ]. It should be noted that TiO 2 in the TiO 2 /g-C 3 N 4 heterojunction is a wide-band-gap semiconductor that responds to UV light (Eg = 3.2 eV; λ ≤ 387.5 nm) [ 99 , 100 ], while g-C 3 N 4 responds to visible light.…”

“…In the preparation of a TiO 2 /g-C 3 N 4 heterojunction, two-step processes have generally been applied in two different ways [ 82 , 83 , 84 , 85 , 86 , 87 , 88 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 ]. The first approach involves the prior synthesis of both TiO 2 and g-C 3 N 4 from the corresponding precursors and subsequent mixing [ 87 , 88 , 92 , 95 , 96 , 97 , 98 ].…”

Nanocomposites constructed with heterostructures of graphitic carbon nitride (g-C3N4), silver (Ag), and titanium dioxide (TiO2) have emerged as promising nanomaterials for various environmental, energy, and clinical applications. In the field of textiles, Ag and TiO2 are already recognized as essential nanomaterials for the chemical surface and bulk modification of various textile materials, but the application of composites with g-C3N4 as a green and visible-light-active photocatalyst has not yet been fully established. This review provides an overview of the construction of Ag/g-C3N4, TiO2/g-C3N4, and Ag/TiO2/g-C3N4 heterostructures; the mechanisms of their photocatalytic activity; and the application of photocatalytic textile platforms in the photochemical activation of organic synthesis, energy generation, and the removal of various organic pollutants from water. Future prospects for the functionalization of textiles using g-C3N4-containing heterostructures with Ag and TiO2 are highlighted.

“…The contact angle (CA) of the membranes was measured on a Krüss DSA 30 (Krüss Company, Ltd., Germany) apparatus. [24,25]. The basic building block of this kind of sodium titanate structure is TiO 6 octahedron, the edge of which forms a negatively charged layered structure, and the opposite cation of Na + is located between adjacent layers, resulting in a variable layer spacing [26][27][28].…”

In this work, a free-standing sodium titanate ultralong nanotube membrane for multifunctional water purification has been prepared. For obtaining this free-standing membrane with good tenacity, one-dimensional (1D) sodium titanate ultralong nanotubes with a diameter of about 48 nm and length of hundreds of micrometers were prepared from TiO 2 nanoparticles by a stirring hydrothermal method, which can be easily assembled into 2D membranes by facile vacuum filtration. After modified with methyltrimethoxysilane (MTMS), the free-standing membrane with hydrophobic surface possesses oil-water separation, self-cleaning and photocatalytic functions at the same time, which is favorable for the recovery of membrane and decontamination of various pollutants including oils, dust, and organic dyes from water. Furthermore, this membrane also exhibits excellent alkaline, acid, and corrosive salt resistance. This free-standing sodium titanate membrane with multifunction has potential applications in efficient wastewater purification and environmental remediation.
