For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
(PWA) [1]. PWA was first converted into H3PW12O40×6H2O (6-PWA) by heating it to
80 °C in a kiln. The aqueous PrCl3×H2O solution was prepared by dissolving 0.7102 g
of PrCl3×H2O in distilled water. This solution is then mixed with aqueous solution of 6-
PWA, slightly heated in order to start the crystallization process and left overnight to
finish the crystallization. The produced greenish crystals of praseodymium doped
phosphate tungsten bronze are created by heating the obtained salt PrPW12O40×nH2O in
a furnace from room temperature to 600 °C. The conditions for thermal phase
transformation of praseodymium salt of 12-tungstophosphoric heteropoly acid to
produce new praseodymium phosphate tungsten bronze, have been investigated in the
current work. The new material (Pr-PWB), synthesized from Keggin's anion structure... as
a precursor, is successfully formed. The potential practical application of Pr-PWB is in
its installation in batteries and fuel cells, as a catalyst, and due to its specific green color
it could also be used as a pigment.
