摘要
We report the use of transition metal precursors impregnated into the pores of CPO-27(Co) metal-organic framework (MOF) crystals prior to pyrolysis as a straightforward strategy for tuning the properties of MOF-derived Co-based catalysts. By adding a Nb inorganic salt prior to pyrolysis hierarchical pores are formed in the resulting carbon and the Co accessible surface area is greatly increased leading to a strong enhancement of CO hydrogenation activity. Graphic Enhancing the activity of MOF-MS Co catalysts for syngas conversion by introducing Nb by impregnation into the pores of CPO-27(Co).
