Plasmon-assisted facile selective gaseous isopropanol dehydrogenation over Ag nanocubes

The present research showed that the non-heating effect of plasmonic absorption caused a great increase in the acetone dehydrogenation over Ag nanocubes in high selectivity at low temperatures.

Synthesis of Novel Geopolymer Supported Nano Bimetallic Catalysts and its Application for Isopropanol Dehydrogenation

A novel geopolymer supported nanobimetallic catalyst for isopropanol dehydrogenation was prepared by modified wet impregnation and reduction method. XRD, SEM, EDX and TEM analysis confirmed formation of amorphous geopolymer from the polymerization of metakaolin and deposition of nanometals over the geopolymer support. The bimetallic catalyst containing 5wt. % Cu and 10wt. % Ni loading over geopolymer shows an excellent performance with 23.18% conversion of isopropanol and 88.24% selectivity to acetone under reaction conditions of 90 °C, 3 hours, and catalyst amount of 0.15g/5.0g of isopropanol. Moreover, the catalyst maintains its catalytic stability without noticeable loss of activity after five cycles.
