Two Factors

The addition of Ba on the improvement of hydrothermal stability over Cu/BEA: (i) stabilize the dispersion of Cu species and suppress the formation of CuO clusters; (ii) the higher redox property. These two factors decide the higher hydrothermal stability over CuBa/BEA-HT rather than Cu/BEA-HT.
