Effects of NiMoO4 impregnation on the catalytic activity of Cu3 (PO4)2 in the conversion of isopropanol

Abstract

Hereby, we are describing the synthesis and characterization concerning acid -basic properties of catalysts containing varied amounts of NiMo (2-14 wt % of NiMoO 4 ) worn on copper orthophosphate whose its preparation was executed employing a co-precipitation method, to which we introduced the Nickel-Molydenum by impregnation with a porous volume at several stages, succeeded by calcination under air at a different temperature. The employed techniques for solids’ characterization were XRD to identify different phases, Nitrogen adsorption at-196°C. and catalytic conversion of isopropanol at different temperatures’ reaction ranging from 180 to 400 °C. The outcome revealed that the solids NiMo/CuP mainly consisted of copper phosphate Cu 3 (PO 4 ) 2 together with NiMoO 4 as minor phase. The NiMoO 4 crystallinity’s degree increases by increasing Nickel-Molydenum. It was discovered that the specific area (S BET ) of the studied system will slightly increase by the increase in NiMoO 4 content. The catalytic activity in isopropanol conversion which proceeds via dehydration yielding propene increases as a function of extent of loading.
