The 2O 3 catalyst with significantly improved catalytic behavior can be potentially used in CO hydrogenation to produce higher alcohols. In addition, the 3D hierarchical structure of the 2O 3 catalyst facilitates mass diffusion/transportation as well as prevents hotspot formation, accounting for its stability and recyclability. XPS, in situ FTIR spectroscopy and HAADF-STEM revealed that the unique electronic and geometric interaction between Cu and Co in the NPs contributes to the significantly enhanced catalytic performances. The composition, particle size and shell thickness can be tuned by changing the Cu/Co molar ratio in the LDH precursors, and the best catalytic behavior was obtained over the Cu/Co (1/2) catalyst with a CO conversion of 21.5% and a selectivity (C 6+ slate 1-alcohols) of 48.9%, which is superior to the traditional modified FT catalysts. Silver nanoparticles supported over Al2O3 Fe2O3 core-shell nanopar. The role of the Cu 2 O shell is truly to enhance the separation, collection, and transport of the electrons and holes photogenerated in the GaN core to boost the photocurrent of the visible-blind UV PEC PD operating in the self. A hybrid magnetic material Fe2O3Shcu2O was easily prepared from Shilajit (Sh). Herein, we demonstrate the fabrication of core–shell nanoparticles (NPs) embedded on a Al 2O 3 matrix via an in situ growth of CuCoAl-LDH nanoplatelets on aluminum substrates followed by a calcination–reduction process, and they serve as efficient catalysts toward CO hydrogenation to produce higher alcohols. Therefore, the Cu 2 O shell does not contribute significantly to the photocurrent by absorption of visible light. Co, Fe, Ni) are efficient and cost-effective candidates. project in the field of core-shell nanocomposites under Prof G. The production of higher alcohols by the catalytic conversion of synthesis gas (CO + H 2) is one of the most promising approaches for the utilization of nonoil resources, in which bimetallic catalysts based on Cu and Fischer–Tropsch (FT) reaction active elements ( e.g. of Cu2O/Al2O3 and Cu/Cu2O interfaces by a Cu/Al2O3 interface 4.
