Over the years, there has been an emphasis on the improvement of novel materials for photocatalytic processes for practical application in treating wastewater. In this sense, the ultrasonic-assisted in-situ chemical polymerization route was used to synthesize polypyrrole-multiwall carbon nanotubes (PPy-MWCNTs) nanocomposites. The transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and ultraviolet visible (UV-vis) analysis were employed to study the impact of MWCNTs on the properties of PPy. TEM showed that the PPy-MWCNTs nanocomposites consist of spherical PPy with 80 nm particle size, while the MWCNTs showed inner and outer diameters of 7 nm and 13 nm, respectively. XRD analysis showed that the crystallinity of the PPy increased with MWCNTs loading. The potential of PPy-MWCNTs nanocomposites as photocatalysts was evaluated via the photodegradation of rhodamine B (RhB) and methylene blue (MB) dyes. The photodegradation efficiency was found to have improved with increasing MWCNTs loading. Almost 99.36% and 78.30% of RhB and MB dye degradation were achieved after 35 min of reaction for the highest loading of MWCNTs. The remarkable nanocomposite photocatalytic activity was attributed to the optical bandgap energy (E g ) reduction with the addition of MWCNTs. These results foreshadow the potential use of the PPy-MWCNTs nanocomposites for water purification.

“…BiOI can degrade many pollutants such as methyl orange (MO), methylene blue (MB), Rhodamine B (RhB), and phenol under visible light, and it also can photocatalyze the production of hydrogen and photocatalyze the sterilization [12][13][14]. However, the serious charge recombination and narrow band gap limit the practical applications of modified BiOI [15,16].…”

The BiOI/NH2-MIL-125(Ti) composite photocatalyst with excellent photocatalytic performance was prepared by the solvothermal method. For the BiOI/NH2-MIL-125(Ti) (BNMT) system, the contents of NH2-MIL-125(Ti) in BNMT-4, BNMT-5, BNMT-7, BNMT-9, and BNMT-10 were 4 wt %, 5 wt %, 7 wt %, 9 wt %, and 10 wt %, respectively. XRD, XPS, SEM, and TEM characterizations indicated that BiOI/NH2-MIL-125(Ti) was successfully prepared. Brunauer, Emmett, and Teller (BET) and UV–vis diffuse reflectance spectra photoelectrochemical analysis indicated that BNMT-9 can make the specific surface area and photo absorption region larger than BiOI. In addition, the separation efficiency of photogenerated carriers was improved, and the recombination efficiency was reduced. The degradation percentages of Rhodamine B (RhB) and p-chlorophenol (P-CP) reached 99% and 90% over BNMT-9 under visible light irradiation. Additionally, the catalysts had high stability. The results of the active spices trapping experiments test indicated that h+ was the main active species. The possible degradation mechanism was proposed.

“…Indeed, the use of fibers such as carbon fibers as a supporting of BiOX lead to improved photocatalytic efficiency compared to photocatalyst alone [24][25][26][27]. In addition, other fibers without optical proprieties have also been tested as a support for bismuth oxyhalide such as luffa fiber [28], Al 2 O 3 -based ceramic fibers [29,30], glass fiber cloth [31] and cellulose fiber [32]. The combination between the semiconductor and an optically inactive support sometimes contributes to improve the adsorption and photocatalytic degradation of the pollutant.…”
