The recoveries for the determination of AA in human serum were obtained at 94.63–105%. These results manifested that CuBTC@PW12 could be used as a peroxide-mimetic enzyme for the continuous detection of H2O2 and AA with the advantages of simplicity, efficiency, sensitivity and accuracy.Song ...
Catalytic formation of acetic anhydride over tungstophosphoric acid modified SBA-15 mesoporous materials Tungstophosphoric acid H 3PW 12O 40 (TPA) was impregnated on mesoporous materials SBA-15 with pore sizes 91.9 and 63.9 at different loadings. TPA-containi... NY He,CS Woo,HG Kim,... -...

A series of H3PW12O40 (HPW)-modified Fe2O3 catalysts for the selective catalytic reduction of NOx by NH3 (NH3-SCR) were synthesized via impregnation of HPW on Fe2O3 micro-flowers followed calcination. The optimum HPW/Fe2O3-350-0.5 catalyst exhibits nearly 100% of NO conversion at 240...
Synthesize of methylamine from methanol and ammonia was studied in this research work using a partiallypotassium heteropoly salt (K3-xHxPW12O40 abbreviated as KPW) as a catalyst. KPW was prepared from heteropoly salt and potassium carbonate by using ion exchange method. The reaction was conducted...
thevisiblewavelength range. From XPS and UV–vis spectra, it was confirmed that LBL coating was attained using the same thicknesses between Keggin ions and TiO2. For IPA decomposition, PW12was the most effective for the combination with TiO2. The PMo12possessed the highest adsorption capability ...
H3PW12O40/SiO2: an efficient, reusable and eco-friendly catalyst for the synthesis of 1,1-diacetates at room temperature12-Tungstophosphoric acid (TPA), is known to be very active catalyst for both homogeneous and heterogeneous acid catalyzed reactions. This allows it to be used as catalyst...
A series of different loading H_3PW_(12)O_(40)SiO_2 and HPW/diatomite were prepared by a typical incipient wetness impregnation of methanol, meanwhile SiO_2 and diatomite supported Cs-salt catalysts were prepared via two-step impregnating method. The catalysts were investigated by X...
In the case of atrazine, an analogous treatment for Cs3PW12O40 yields K=1.4(±0.1)×104 M−1 while the value for TiO2 is at least an order of magnitude less. The quantum yields indicate the importance of heterogeneity of the photocatalyst surface for Cs3PW12O40, where the concentration...
