S0 manuf. from H2S by oxidn. with O2 in an aq. acid contg. P-Mo-V heteropoly compds. as a catalyst and then regenerating the catalyst was improved to increase the selectivity and catalyst regeneration by using a heteropoly anion of compn. [PMoVI12 - nVVn - iVIViO40]3+n+i (n = 4-8, 2 ≤ i < n) as the catalyst.
