VISIBLE-LIGHT-ACTIVE NITROGEN DOPED TIO2 NANOPARTICLES PREPARED BY SOL-GEL ACID CATALYZED REACTION

Yellow-colored nitrogen doped TiO2 photocatalyst and a pure TiO2 powder were synthesized via sol-gel method using TiCl4 and urea as raw materials. However, the synthesis procedure for nitrogen doped TiO2 was catalyzed by acid that dialed with controlled precipitation and slow nucleation. According to XRD analysis, the nitrogen doped TiO2 consisted of anatase phase of titania which was a signifi...

Competition between Silver Ions and Oxybromine Species for Bromide Ions in the Silver-Perturbed Beiousov-Zhabotinskii Reaction

one-humped, next-maximum map is in this region. More complex maps certainly do occur in the experiment^.^^.'^ We never saw a truly single-valued simulated next-maximum map; nevertheless, the maps in Figures 3b and 4a would certainly appear single-valued in the presence of even a low level of experimental noise, and there are indication^^^ that all experimental maps may consist of multiple sheet...

Role of Dibromomalonic Acid in the Photosensitivity of the Ru(bpy)3-Catalyzed Belousov-Zhabotinsky Reaction

The photosensitive Belousov-Zhabotinsky (BZ) reaction catalyzed by the Ru(bpy)3 metallo-complex has been widely utilized in recent years. It has been employed in image processing,1 for pattern formation,2 in studying traveling,3 spiral,4,5 and scroll waves,6 as well as in investigations of stochastic resonance.7-9 Understanding the mechanism of photosensitivity in this reaction may facilitate t...

Phase transfer catalyzed reaction of disodium salt of 1,3-dihydroxybenzene with propargyl bromide in solid-liquid biphasic condition

The present work describes, the reaction between disodium salt of 1,3-dihydroxybenzene (in situ formation) and propargyl bromide was carried out in a solid-liquid biphasic phase transfer catalytic system at 50°C. Higher selectivity of the bis-derivative (1,3-bis(prop-2-ynyloxy)benzene) was obtained under solid-liquid PTC condion. The conversion of propargyl bromide of more than 99% was achieved...
