“…It was clear that the TiO 2 modified cotton fabric exhibited a typical absorption to UV rays rather than visible lights, while the pristine cotton fabric had little resistance to UV rays. 75 This was because the electrons in the valence band could be excited into the conduction band in anatase TiO 2 . 68 It was demonstrated that the absorption ability of TiO 2 in visible light region was distinctly enhanced when RGO was introduced.…”

The self-cleaning textiles coated with reduced graphene oxide-titanium dioxide (TiO2) nanocomposites have enhanced photocatalytic activities and could have great potential in practical applications. However, it is still problematic regarding how to avoid aggregation of reduced graphene oxide nanosheets in producing reduced graphene oxide-TiO2 nanocomposites. In this research article, we propose a new method to reduce the aggregation of reduced graphene oxide nanosheets in producing cotton fabrics coated with reduced graphene oxide-TiO2 nanocomposites by combining vibration-assisted ball milling and hydrothermal synthesis process. The microstructure and photocatalytic-related properties of the resultant reduced graphene oxide-TiO2 nanocomposites and their coating cotton fabrics were characterized by using a series of techniques including field emission scanning electron microscope (FESEM), atomic force microscope (AFM), X-ray diffraction spectroscopy (XRD), Raman, particle size distribution, Brunauer-Emmett-Teller,(BET), transmission electron microscope (TEM), X-ray photoelectron spectrometer (XPS), diffuse reflectance spectra (DRS), ultraviolet photoelectron spectroscope (UPS), and photoluminescence (PL). It was indicated that the aggregation of reduced graphene oxide nanosheets in reduced graphene oxide-TiO2 nanocomposites was successfully avoided via ball milling in the presence of tetrabutyl titanate. After hydrothermal treatment, the resulting reduced graphene oxide-TiO2 nanocomposites were firmly immobilized on cotton fabric. It was demonstrated in the self-cleaning experiments that the resultant self-cleaning cotton fabrics are hydrophilic and could directly decompose color contaminants such as methylene blue, Congo red, and coffee stains under simulated sunlight irradiation due to the photo-degradation reactions of the reduced graphene oxide-TiO2 nanocomposite coating. The reduced graphene oxide-TiO2 nanocomposite-modified cotton fabric also exhibited excellent performance in both robust abrasion resistance and soap-washing resistance. The fabric photocatalytic self-cleaning capability was not found to decrease significantly after being repeatedly used for five times.

“…Chen et al showed that the g-C 3 N 4 mass ratio of 72% provides the highest photocatalytic performance, which is 17 times higher than bulk g-C 3 N 4 [303]. SnO 2 -g-C 3 N 4 heterojunction reveals notable stability and recyclability [18]. In addition to robust photocatalytic activities, this composite has a noticeable photoelectrochemical performance under visible light.…”

“…Among them, metal oxides are the most common ones to improve the efficiency of g-C 3 N 4 , e.g., increasing the light absorption and reducing the recombination of electrons and holes by promoting the separation of charge carriers. This is mainly due to their suitable band structures [13][14][15][16][17][18].…”

g-C3N4 has drawn lots of attention due to its photocatalytic activity, low-cost and facile synthesis, and interesting layered structure. However, to improve some of the properties of g-C3N4, such as photochemical stability, electrical band structure, and to decrease charge recombination rate, and towards effective light-harvesting, g-C3N4–metal oxide-based heterojunctions have been introduced. In this review, we initially discussed the preparation, modification, and physical properties of the g-C3N4 and then, we discussed the combination of g-C3N4 with various metal oxides such as TiO2, ZnO, FeO, Fe2O3, Fe3O4, WO3, SnO, SnO2, etc. We summarized some of their characteristic properties of these heterojunctions, their optical features, photocatalytic performance, and electrical band edge positions. This review covers recent advances, including applications in water splitting, CO2 reduction, and photodegradation of organic pollutants, sensors, bacterial disinfection, and supercapacitors. We show that metal oxides can improve the efficiency of the bare g-C3N4 to make the composites suitable for a wide range of applications. Finally, this review provides some perspectives, limitations, and challenges in investigation of g-C3N4–metal-oxide-based heterojunctions.

“…For the transformation of furfuryl alcohol, Brönsted acids such as H 2 SO 4 , HCl, p-toluensulfonic acid, H-ZSM-5 (an acidified commercial zeolite), hyaluronic acid or Amberlyst-15 (a strongly acid exchange resin) readily catalyse the hydrolysis reaction, favoring the production of levulinic acid [81,82]. For example, when using Amberlyst-15, only a 16.5% selectivity towards the HCP is achieved, yielding mostly levulinic acid as the product.…”
