“…The degradation of these pollutants by conventional methods is insufficient and lead to several side effects [4,5]. The application of nano-size photo-catalysts in degradation of organic pollutants in aqueous environment has concerned much interest due to their large surface area [6][7][8][9][10][11]. Semiconductor nano-particles have attracted many interests for their interesting properties and applications in photocatalysis [12][13][14][15].…”

“…[18][19][20]. The absorption band around 444 cm -1 is due to Zn-O vibration mode [20][21][22]. The FT-IR spectra of ZAD-Li and ZAD-Li,Ni samples, thermally treated at 257 o C, show similar behavior with undoped sample, as can be seen in the Figure 10.…”

“…In the 1010-1145 cm -1 region the observed bands are explained as the symmetric and asymmetric stretching modes of C-O bond in the acetate group. Below 686 cm -1 the bands are due to Zn-O vibration [17][18][19][20][21][22]. In the spectra of the doped samples the intensity of the Zn-OH band at 623cm -1 increased, and the bands at 502 and 420 cm -1 became more intense.…”

“…The bands in the low frequency region 429-485 cm -1 correspond to the lattice vibration mode of Zn-O [18][19][20][21][22] for doped and un-doped samples. The bands are shifted to lower wavenumbers in doped samples.…”

“…The bands are shifted to lower wavenumbers in doped samples. Small bands at 1507 cm -1 and 1123 cm -1 are assigned of organic adsorbed species [18][19][20][21][22]. During annealing the gels, zinc-acetate decomposed between 110-350 °C with the release of CH 3 COOH, acetone and CO 2 .…”

ZnO, Li doped and Li,Ni co-doped ZnO powders to be later used as transparent conductive oxide (TCO) thin film were prepared by heat treatment of gels obtained from alcoholic Zn(CH 3 COO) 2 •2H 2 O, LiNO 3 •nH 2 O and NiSO 4 •6H 2 O solutions with (CH 3 CH 2 OH) 3 N as chelating agent. The properties of the powders and their thermal treatment were studied by thermogravimetric and termodifferential anlysis (TG/DTA), differential scanning calorimetry (DSC), evolved gas analysis coupled with mass spectroscopy (EGA-MS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy coupled with energy dispersive X-ray (SEM/ EDX). The as-prepared gels consisted of submicron platelet-like particles and contained zinc acetate dihydrate and hydrozincite in different amount and with different preferred orientations. During annealing the gels, zinc-acetate decomposed between 110-350 °C with the release of CH 3 COOH, acetone and CO 2 . The N content of the chelating agent was responsible for NH 3 and NO evolution. The thermal behavior of the doped 3 gels was similar, but there were also differences in the mass losses, amount of released gases.Based on TG/DTA data, ZnO powders were obtained from the gels by annealing both at 275 and 500 °C. After heating at 275 °C, the obtained powders consisted of spherical 1-2 micron grains of wurtzite. The inclusion of the dopants was successful according to EDX and cell parameter data. Thermal study of the powder annealed at 275 °C confirmed that they still contain some zinc acetate. In the case of the doped samples the mass loss was smaller, since the Li and Ni dopants catalized the composition of zinc acetate during the previous annealing at 275 °C. After annealing the gels at 500 °C, stable un-doped ZnO or doped ZnO particles were obtained.
