In this investigation, the use of phosphotungstic acid (PWA) and phosphomolybdic (PMA) as well Zn2+ containing kaolin bentonite explored for chemical recycling post-consumer poly(ethyleneterephthalate) (PET) wastes have been explored. The clay supported catalysts 5wt% metals heteropolyacids (HPAs) synthesized using wet impregnation method. Nitrogen adsorption desorption studies, SEM–EDX mapping...
