A novel K-promoted Cu-Fe bimodal derived catalyst was designed to optimize the catalytic activity and higher alcohols selectivity in higher alcohols synthesis (HAS). The characterization results indicated that the Cu-Fe bimodal derived catalyst presented the bimodal pore structures. The adding of K promoter increased the BET surface area and promoted the dispersion of Cu and Fe species in the bimodal...
A Cu–Fe supported bimodal pore catalyst prepared by incipient-wetness impregnation exhibited two kinds of nano-pores. Increasing amount of copper and iron species decreased BET surface area and the size of both the small pores and large pores, while promoted the aggregation of bi-metal particles inside the large pores. Higher bimetal species content in the bimodal derived catalyst facilitated the...
