“…The stretching of N-H and C-H groups can be observed in 3344 and 2923 cm −1 peaks, respectively. The stretching vibration band of the azo group N=N appears in wavenumbers of 1554 cm −1 [58]. The asymmetry stretching vibration of S-O group can be appreciated due to the transmittance peak at 1405 cm −1 [59].…”

This work provides an alternative method for evaluating the photodegradation behaviour of different types of dyes such as Methylene Blue, Rhodamine B, Congo Red, Metanil Yellow, and Malachite Green. In this methodology, the coating is dyed with the chosen colorant and two beams of light are combined and channelled to a spot on the dyed coating through an optical fibre, the first one from an ultraviolet (UV) source (which is the responsible of activating photocatalysis) and the second one from a Visible light source, which is employed to monitor changes in colour along the time. The photocatalytic coating selected for testing this methodology consists of a mat of electrospun poly (acrylic acid) (PAA) fibres that acts as base film, furtherly coated by using layer-by-layer (LbL) assembly technique for the immobilization of two different photocatalytic metal oxide precursors (TiO2 and Fe2O3) nanoparticles. The morphological characterization of the samples has been implemented by means of scanning electron microscopy (SEM), confocal microscopy, and water contact angle measurements in order to analyse the resultant thickness, roughness, electrospun fibre diameter, and wettability. The experimental results clearly demonstrate the validity of the methodology to measure the photocatalytic activity in all dyed coatings, although significant differences have been observed depending on the selected dye.

“…The working electrode was made by immersing FTO glass coated with TiO2 in a 1000 ppm metal complexes for 24 hours, and then the FTO glass was taken and dried at room temperature. Then the FTO glass is stored in a dark box to avoid scratches and sunlight [14][15].…”

“…The higher the incoming light, the higher the current value produced. This is because the current in the DSSC cell is strongly influenced by the photons absorbed by the dye sensitizer in the DSSC cell [14]. When compared among the three metal-phen complex compounds, the highest current is produced by the [Ni(phen)3] 2+ complex compound, which is 0.452 mA.…”

The use of metal complexes as a dye sensitizer in DSSC (Dye-Sensitized Solar Cells) provides many promising opportunities. Complex compounds with ligands that actively absorb UV rays have the potential to be applied in technology solar cells in areas rich in UV rays such as Indonesia. This research aim is to investigate the potential of several complex compounds with UV active ligands and apply them as dye sensitizer in DSSC. Ligand phenanthroline (phen), and morin will be synthesized with several transition metals. The synthesized metal complexes were characterized by spectrophotometer UV-VIS (for all metal complexes) and spectrophotometer FTIR (for morin complexes). The performance of metal complexes as dye sensitizer will be analyzed from the current and voltage obtained and in this research was limited to the phenanthroline complex compound because the research was still in the ongoing process. The highest current produced by [Ni(phen)3]2+ with 0.452 mA while the highest voltage produced by complex [Fe(phen)3]2+ with 711 mV.

“…Despite the risks resulting from the use of this dye, there are sectors in which it is still used, for example in the textile industry because of its affinity with cellulose fibers, and in the cosmetic, pharmaceutical, and stationery industries. Setyawati and co-workers [ 11 ] carried out a study in which they functionalized Congo Red dye to improve its photovoltaic performance (by forming complexes with metals such as Fe, Ni, and Co). The purpose of this functionalization was to use the complexes in solar cells.…”

The aim of this study was to synthesize a CoFe2O4@HaP nanocomposite (HaP-Hydroxyapatite) through the coprecipitation method in aqueous solution, with the purpose of using it in adsorption processes for the removal of Congo Red dye from aqueous solutions. Fourier Transform Infrared Spectroscopy (FT-IR) was used to characterize the synthesized material, identifying absorption bands specific to the functional groups of cobalt ferrite (Fe-O and Co-O at 603 and 472 cm−1) and hydroxyapatite PO43− at 1035, 962, 603 and 565 cm−1. Powder X-ray diffraction confirmed the cubic spinel structure of cobalt ferrite (S.G Fd-3m) and the hexagonal structure of hydroxyapatite (S.G P63/m). The nanocomposite’s crystallite size was calculated to be 57.88 nm. Nitrogen adsorption/desorption isotherms and BET specific surface area measurements were used to monitor textural parameters, revealing an increase in specific BET surface area when cobalt ferrite nanoparticles (15 m2/g) were introduced into the hydroxyapatite heterostructure (34 m2/g). Magnetic properties were investigated by interpreting hysteresis curves in the ±10 kOe range, with the nanocomposite showing a saturation magnetization of 34.83 emu/g and a coercivity value of 0.03 kOe. The adsorption capacity of the CoFe2O4@HaP nanocomposite is up to 15.25 mg/g and the pseudo-second-order kinetic model (Type 1) fits the data with a high correlation coefficient of 0.9984, indicating that the chemical adsorption determines the rate-determining step of the process. The obtained nanocomposite is confirmed by the analyses, and the absorption measurements demonstrate that it can be utilized to degrade Congo Red dye.
