was examined as a function of the [Cu2+] or [PW12O 3-40 ] in the electrodeposition bath. The influence of nickel salt anions on the h.e.r. electrocatalytic activity of the electrodes was also investigated. The chemical surface composition of the electrodes was analysed by X-ray ...
摘要: GaxCs2.5-3xH0.5PW12O40 (x=0.05,0.10,and 0.15) salts were prepared using a solid synthesis method and they showed higher catalytic activity than that of Cs2.5H0.5PW12O40 for n-butane isomerization,which possibly comes from their enhanced acid strength as a result of Ga doping....
The bimetal-bearing (CePt or LaPt) 12-tungstophosphoric acid (H3PW12O40 (PW)) catalysts supported on dealuminated USY zeolite (DUSY) were prepared by impregnation and characterized by XRD, BET, IR, and H2-chemisorption. Their catalytic activities were tested in the hydroisomerization of n-...
12O40/SiO2Sensitized by H2O2 doi:10.1155/2012/927132In order to remove aquatic organic dye contaminants by utilizing the inexpensive and inexhaustible solar energy, the Keggin-type H3PW12O40 was loaded on the surface of SiO2 with the sol-gel method and sensitized by H2O2 solution. The ...

who published only a fraction of his writing before his death, had one brief romance, extolled the virtue of “doing nothing in life,” and ended one of his last poems with the summation, “Give me more wine, because life is nothing.” But while Pessoa may have been light on wor...
Microwave-Assisted Synthesis of HKUST-1 and Functionalized HKUST-1-@H3PW12O40: Selective Adsorption of Heavy Metal Ions in Water Analyzed with Synchrotron ... Li, W. Li, Microwave-assisted synthesis of HKUST-1 and functionalized HKUST-1-@ H3PW12O40: selective adsorption of heavy metal ions ...
A magnetically retrievable and stable composite, Fe3O4@SiO2-NH2/HPW@CS/HPW, in which H3PW12O40 (abbreviated as HPW hereafter) was successfully anchored onto the surface of a cross-linked chitosan coating on magnetic Fe3O4 cores, has been prepared by means of chemical bonding between the...
Silica-supported heteropoly acid H3PW12O40 (PW) is a very efficient and environmentally benign solid acid catalyst for the liquid-phase cyclization of (+)-citronellal (1). The reaction has been performed in cyclohexane solutions at 15–40 °C yielding (−)−isopulegol (2) and (+)-neo...
The Cs2.5H0.5PW12O40 nanoparticle catalyst appear to be a new and efficient solid acid catalyst for an economical, environmentally benign synthesis of (S)-(-)-propranolol. Cs2.5H0.5PW12O40 nanocatalyst are used as a new, recyclable and reusable. Synthesis of (S)-(-)-propranolol is ...
