Recently, two different effects of phosphate tungsten (PWB) and phosphate
molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory
Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble in
BR solution [2], the addition of different masses of PWB linearly decreases the BR
oscillation time, while the addition of different masses of PMoB had no effects on
the BR reaction. Furthermore, PWB has an identical role as metal catalyst Mn2+ in
BR reaction and for obtained behavior is probably responsible the different
mechanisms of heterogeneous catalysis of these bronzes in oscillatory reaction.
Therefore, a deeper investigation was done in order to find the major structural
characteristic of these two bronzes by using the XRPD method.
What is so different for these two bronzes, causing dissimilar effects in BR
reaction, is it “just” catalytic activity of central cation or there is something more?
The XRPD method confirmed very different struct...ures of PWB and PMoB as
monoclinic and orthorhombic, respectively [3,4]. This work tries to connect the
structural properties of PWB and PMoB with BR oscillatory reaction responses,
expanding the usage of oscillatory reaction in material science and catalysis, in
general.
