Bixin is a natural dye belonging to the carotenoid group that has been reported to have many health benefits. In this work, for the first time, metal-bixin complexes were synthesized through a simple green route using deep eutectic solvent (DES) as reaction media. DES was produced by stirring choline chloride and glycerol with a molar ratio of 1:3. The metal-bixin complex was prepared by grinding and stirring bixin and divalent metal ions (Mg2+, Ca2+, Zn2+, Cu2+, separately) in DES at room temperature. DES formed in this work was a homogeneous colorless liquid with a freezing point below -20 °C. It has a pH, density, viscosity, and conductivity of 7.13, 148.99 cP, 1.207 g/cm3, and 1.8 mS/cm, respectively. UV-Vis spectrophotometric analysis shows that the absorption spectra produced by the Mg(II)-bixin, Ca(II)-bixin, Zn(II)-bixin, and Cu(II)-bixin complexes show an insignificant shift in the direction of a larger wavelength (red shift) compared to pure bixin. Spectral fine structure expressed as %III/II, i.e., the ratio of the height of the longest-wavelength absorption to the middle absorption peak. The value of %III/II for bixin, Mg(II)-bixin, Ca(II)-bixin, Zn(II)-bixin, and Cu(II)-bixin are 16.77, 20.37, 17.39, and 13.52%, respectively. The results of the FTIR spectra analysis confirmed that the bond between bixin and metal ions occurred in the carboxylate acid group, indicated by a decrease in the absorption intensity at wavenumber 3389 and 1716 cm−1.

“…Bixin has been shown to reduce the inflammatory response and atherosclerotic plaque in hypercholesterolemic rabbits [4] and prevent neuroinflammation and demyelination in mice [5]. Rahmalia et al [6][7] used bixin as a sensitizer, such as a light filter, so it has the potency to protect food products from oxidation due to light.…”

“…The stability of kaolinite-bixin organoclay increased up to 15% compared to pure bixin [8]. Another study has reported that when used as a sensitizer, the Znbixin complex can be stable up to 700 W m -2 irradiation [7]. However, most of the previous studies observed the performance of DSSC based on the maximum energy conversion efficiency parameter.…”

Dye-Sensitized Solar Cells or DSSC is the latest solar cell type generation that uses natural dyes as sensitizers. Bixin extracted from the seeds of kesumba (Bixa orellana L) is one of the natural dyes that can be used as a sensitizer. This study aims to determine the effect of the active surface area of solar cells on the effectivity and reusability of bixin-sensitized solar cells based on their open-circuit voltage (Voc), short-circuit current (Isc), and maximum energy conversion efficiency. The results of this study will provide an overview of the best surface area to produce DSSC with the highest maximum energy conversion efficiency and the lifetime of bixin sensitized solar cells. The measurement results showed that the resulting Voc for each variation of the surface area 1, 2, and 3 cm2 was 344; 719; 1002 mV under intensity 100 mW cm-2, while the Isc produced under the same intensity was 0.223; 0.471; 0.680 mA. Based on the calculation results, the maximum power generated by each surface area was 0,077; 0,338; 0,681 W. This means that the larger the active surface area of the solar cell, the greater the voltage and current generated. In this work, the highest efficiency was produced by solar cells with a surface area of 2 cm2, which is 0.085%. The solar cells fabricated in this study can be reused for five days under continuous irradiation.

“…On the other hand, several studies have shown that the photochemical efficiency of TiO 2 can be improved by the use of sensitizers [ 53 , 54 , 55 , 56 ], including transition metal coordination complexes, such as the Cu(C 3 H 3 N 3 S 3 ) 3 complex (Cu-TTC), which was referenced in previous studies [ 57 ]. This complex formed by Cu(I) and trithiocyanuric acid (C 3 H 3 N 3 S 3 ) proved to be an effective photosensitizer in the Cu(C 3 H 3 N 3 S 3 ) 3 /ZnTiO 3 /TiO 2 (Cu/TTC/ZTO/TO) system since it allowed the insertion of e − between the conduction band of the hybrid semiconductor ZnTiO 3 /TiO 2 and the excited molecule [ 58 ].…”

The use of semiconductors for bacterial photoinactivation is a promising approach that has attracted great interest in wastewater remediation. The photoinactivator Cu-TTC/ZTO/TO was synthesized by the solvothermal method from the coordination complex Cu(C3H3N3S3)3 (Cu-TTC) and the hybrid semiconductor ZnTiO3/TiO2 (ZTO/TO). In this study, the effect of photocatalyst composition/concentration as well as radiation intensity on the photoinactivation of the gram-negative bacteria Escherichia coli and the gram-positive bacteria Staphylococcus aureus in aqueous solutions was investigated. The results revealed that 25 mg/mL of photoinactivator, in a Cu-TTC:ZTO/TO molar ratio of 1:2 (w/w%) presents a higher rate of bacterial photoinactivation under simulated solar light (λ = 300–800 nm) in comparison to the individual components. The evidence of this study suggests that the presence of the Cu(C3H3N3S3)3 coordination complex in the ZnTiO3/TiO2 hybrid semiconductor would contribute to the generation of reactive oxygen species (ROS) that are essential to initiate the bacterial photoinactivation process. Finally, the results obtained allow us to predict that the Cu-TTC/ZTO/TO photocatalyst could be used for effective bacterial inactivation of E. coli and S. aureus in aqueous systems under simulated solar light.
