Description
Abstract A facile synthesis of hexagonal α-zirconium phosphate (ZP) nanoparticles as an
effective, eco-friendly and recyclable solid acid catalyst was studied. Polyvinylpyrrolidone
(PVP) and Polyvinyl alcohol (PVA) were used as the organic matrix which were the
dispersing agents and acted as a template for the nanoparticles. It seems H-bonds between
ZP and PVA or PVP along polymer chains lead to a better dispersion of in situ formed ZP.
Pure ZP nanoparticles with hexagonal shape were obtained after calcination of PVA/ZP or ...
