Wastewater-containing dyes are an environmental problem. The prime source of dye pollutants is the textile industry, such as paper manufacturing, food processing, leather, pigments, etc. Dye removal from wastewater using nanotechnology has received attention in recent decades thanks to efficient nanomaterials improving traditional technologies. In recent years, multiple research reports on carbon nanotubes for dye removal and photocatalytic dye degradation provided substantial insight into the comprehension of nanotechnology and remediation. This work presents a review and bibliometric analysis of carbon nanotubes for dye removal and photocatalytic dye degradation, which have an environmental impact today. The bibliometric study showed that the current research tendency on carbon nanotubes applied in dye removal and photocatalysis is still growing. According to research, this work observed that carbon nanotubes for dye removal exhibit high removal and efficient photocatalysis activity, indicating the functionality of nanotechnology for environmental remediation. The analysis of the parameters involved in the removal studies, such as temperature and pH, showed adsorption behavior. The photodegradation of methylene blue demonstrated the photocatalytic activity of carbon nanotubes attributed to the sp2 lattice of graphitic configuration.

Nanocomposites of SiO2/MoO3 having respective weight ratios of 3:1, 2:2, and 1:3 were synthesized using a nanosecond pulsed laser ablation method. The prepared samples were analyzed with UV-Vis and Raman spectroscopy, XRD, SEM, EDX, and TEM. Based on the TEM analysis, the morphology and the structure of the nanocomposites varied with the change in the ratio of MoO3, and the sample containing the highest amount of MoO3 shows a compact morphology and a higher number of nanoparticles. The band gap energy of the nanocomposites increases with an increase in MoO3 load. The nanocomposites were used in the catalytic reduction of 4-nitrophenol (4-NP) in the presence of NaBH4. The reduction time of 4-NP decreases as the amount of MoO3 increases in the nanocomposite. The rate constants were estimated at 0.0878, 0.2319, and 0.1726 min-1 for SiO2/MoO3 (3:1, 2:2, and 1:3) catalysts respectively. The results demonstrate the good catalytic performance of the prepared materials by enabling fast reduction of 4-NP.
