Research Abstract

We could demonstrate that 1) Preyssler-type heteropoly acids(H_14NaP_5W_30O_110 and it' s derivatives) have stronger acid site compared to H_2SO_4 and the most known heteropoly acid, Keggin-type phosphotungstic acid(H_3PW_12O_40), and 2) Ru in Ru-substituted heteporoly anion can act as a Lewis acid site by reacting Ru with pyridine derivatives(Lewis base).
