Porous MgO Supported Ba-Cs-Ru/MgO Catalysts for Superior NH3 Synthesis and the Effect of Ru Loading on Dispersion of Ru and Promoters
Abstract
Porous MgO support through MDCPy is used to prepare superior Ba-Cs-Ru/MgO NH3 synthesis catalysts with outperformed activity than those MgO from other methods. Based on the effect of Ru loading on the dispersion of Ru and promoters, the optimal catalyst appears a quasi-core-shell site of 2.2 nm RuNP@subnano-BaCsOx.
