“…Their reports have been completed with information about parameters involved in the photodecomposition, such as photocatalyst dosage, (Eskizeybek et al, 2012) initial concentration of organic materials, (Matthews 1991) properties of organic materials and catalyst, (Iskandar et al, 2007;Nandiyanto et al, 2009;Nandiyanto et al, 2013;Arutanti et al, 2014) temperature, pH, (Sun et al, 2008) reaction volume, light intensity, type of light sources (Matthews 1991;Eskizeybek et al, 2012) (i.e., artificial UV/visible light source and natural sunlight), turbidity , oxygen gas flow rate , additional chemical (i.e., oxidant, (Sun et al, 2008), reducing agent, co-catalyst, (Arutanti et al, 2014;Arutanti et al, 2015) and dopant (Arutanti et al, 2015)), and consideration of inhibitor. However, there is no report on the photodecomposition of organic materials during the solar eclipse phenomenon.…”

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.

“…The pH at the point of zero charge (pH PZC ) for TiO 2 has been reported to be in the range 6.25-6.90 32 . Thus, the TiO 2 surface is positively charged in acidic media (pH < pH PZC ), and negatively charged under alkaline conditions (pH > pH PZC ).…”

ABSTRACT:The photocatalytic degradation of indigo carmine was investigated by using rubber sheet impregnated with titanium dioxide particles. The characteristics of the impregnated sheet were studied using scanning electron microscopy and X-ray diffraction. The degradation was monitored by measuring the change of dye concentration as a function of irradiation time under UV light. The anatase impregnated sheet showed higher degradation efficiency than the P25 impregnated sheet. The effects of solution pH, dye initial concentration, and intensity of UV light on the photodegradation were investigated. Kinetics of photocatalytic degradation was of a first-order reaction. The used TiO2-impregnated sheets can be recovered and reused with no decline in the photodegradation efficiency.

“…Many reported investigations have revealed that doping with non-metal atoms, such as C, N, F, P or S, can significantly improve the photocatalytic activity of TiO 2 under visible light (Chang et al, 2005;Irie et al, 2003;Ohno et al, 2004Ohno et al, , 2003aSun et al, 2008;Wu et al, 2007). Co-doping of C and N Yang et al, 2008), metal and non-metal co-doping (Neville et al, 2012;Shen et al, 2008; were reported to render materials with high visible light response.…”

a b s t r a c tIn this work, we have successfully synthesized a set of titania photocatalytic nanocomposites by the incorporation of different TiO 2 content on wheat bran residues. The obtained catalysts were characterized by different techniques including UVeVis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Transmission Electron Microscopy (TEM) while their photocatalytic activity was investigated in the oxidation of benzyl alcohol under UV light irradiation. Benzaldehyde yields were ca. 20%, with conversion in the systems of ca. 33% of benzyl alcohol by using 10%Ti-Bran catalyst, as compared to 33% yield to the target product (quantitative conversion of benzyl alcohol) using commercial pure TiO 2 (P-25). The photocatalytic activity results indicate that designed waste-derived nanomaterials with low TiO 2 content can efficiently photocatalyze the conversion of benzyl alcohol with relative high selectivity towards benzaldehyde.
