Reporting their findings in ACS Applied Materials & Interfaces, the researchers state that BaRuO3 has three advantages over conventional catalysts.

Firstly, it exhibits high performance even at 313 K, a temperature much lower than the 373 to 423 K range reported in previous systems including other ruthenium- and manganese-based catalysts. Secondly, its high rate of oxygen transfer indicates that it has many potential uses; for example, it is applicable to the oxidative desulfurization of dibenzothiophene, which can produce a 99 percent yield of pure sulfone. Thirdly, the new catalyst is recyclable—the present study showed that BaRuO3 could be reused at least three times without loss of performance.
