“…These reasons make photodecomposition of curcumin being studied. (Kumavat et al, 2013;Buddee et al, 2014) Another material used in the present study was TiO2 as the photocatalyst. This material was selected due to its affinity for light, and its ability to degrade organic compounds and transfer energy (known as solar cell).…”

“…This material was selected due to its affinity for light, and its ability to degrade organic compounds and transfer energy (known as solar cell). (Nandiyanto et al, 2009) In addition, this material is relatively cheap, easily accessible, and non-toxic (Buddee et al, 2014). Anatase-TiO 2 was used because it has been proven to be the best for photocatalytic activity.…”

The present study investigated the photodecomposition of an organic material during the partial (88.76%) solar eclipse phenomenon of 9 March 2016 in Bandung, Indonesia. Curcumin and anatase titanium dioxide (TiO 2 ) particles were used as models of organic material and photocatalyst, respectively. The influence of the process parameters (i.e., curcumin concentration and the amount of TiO 2 ) on the photodecomposition process was also investigated. The results showed that the curcumin was decomposed along with the solar light irradiation time. During the solar eclipse, the photodecomposition rate is suddenly down. The partial solar eclipse provided a slower photodecomposition process than the process under sunny days (conducted on 8 and 10 March 2016). The concentration of curcumin and the amount of TiO 2 also have played an important role in the photodecomposition, in which the lower concentration of curcumin and the higher amount of TiO 2 have a correlation to the obtainment of higher photodecomposition rate.

Porous photoanodes of dye-sensitized solar cells (DSSCs) can adsorb specific type of natural or organic dyes. Adsorption of the dye results in a change of the structural, morphological and optical characteristics of the photoanode. In this work, we present a comparative study on the adsorption effect of natural dye (Curcuma Longa sp.) on the structural, morphological and optical properties of mesoporous titanium dioxide (TiO 2 ) photoanode on indium tin oxide (ITO) coated glass. A number of investigations including XRD, UV-Vis spectroscopy, EDS, and SEM were carried out to observe the variations due to adsorbed dye on TiO 2 surface. XRD characterization revealed the effect of dye adsorption on specific surface area (SSA), crystallite size, and morphological index (MI). In this case, increasing SSA with decreasing particle size was found for both dye adsorbed and dye free DSSC photoanode samples. Also, the MI and SSA were found to be directly and inversely proportional to the crystallite size respectively. UV-Vis-NIR spectroscopy showed that dye adsorption changes the light absorption, transmittance, and optical bandgap of the photoanode. Average atomic mass percentage of titanium (Ti) and oxygen (O) obtained from EDS analysis proved the presence of TiO 2 in the mesoporous photoanode. In SEM images, significant morphological changes of mesoporous TiO 2 surface appeared because of dye adsorption.

Curcumin-sensitized perovskite Bi 0.5 Na 0.5 TiO 3 (BNT) was synthesized for visible light photocatalytic decolorization of rhodamine 6G (Rh6G). Cube-shaped perovskite BNT was synthesized by solid-state route, and curcumin sensitization was performed using hydrothermal method. The surface sensitization of curcumin was analyzed by UV-Vis absorption spectra and FTIR. The degradation kinetics of Rh6G over Cur-BNT were investigated and discussed through first-order Langmuir-Hinshelwood kinetic model. The effect of catalyst dose on photocatalytic decolorization process was investigated. Photocatalysis was performed with different scavengers to investigate the role of active hole and radical species and photocatalytic degradation mechanism of Rh6G.
