| Abstract [eng] |
The synthesis conditions of AlPO-zeotype using aluminium hydroxide and aluminium isopropoxide feedstocks were investigated. The AlPO-5 ceotype is obtained using aluminium isopropoxide with the addition of N,N-diisopropylethylamine (or DIPEA) The molar composition of the sample is 1 Al2O3:1 P2O5:1 DIPEA:120 H2O and the reaction is carried out in a microwave-induced hydrothermal synthesis reactor at 180 °C for 1 hour. X-ray diffraction analysis and scanning electron microscopy data confirm the formation of hexagonal singonia crystals. The resulting microporous structure is impregnated with copper (II) nitrate trihydrate solution to incorporate Cu2+ ions into the material structure. From the adsorption and atomic absorption spectroscopy studies carried out, a CuO/zeotype catalyst was prepared with a concentration of 150,538 mgCuO per gram of adsorbent. |
