Sci. Technol. VL - 58 IS - 6 SE - Materials DO - 10.15625/2525-2518/58/6/15119 UR - https://vjs.ac.vn/index.php/jst/article/view/15119 SP - 709-717 AB - <p>In this work, nano silver catalyst loaded on vanadium phosphorus oxide (Ag/VPO) for oxidation of styrene to benzaldehyde was synthesized by impregnating method including impregnating of VPO substrate with colloid solution of nano silvers. VPO substrate was prepared by microwave-assisted reaction of vanadium and phosphorus precursors. Meanwhile, nano Ag/PVP was prepared in solution using NaBH<sub>4</sub> as reducing agent and polyvinylpyrrolidone (PVP) as protecting agent and spherical-shaped nano particles with mean diameter of about 7.5 nm determined by transmission electron microscopy (TEM) was obtained. </p> ER -
