Novel hollow microsphere with porous carbon shell embedded with Cu/Co bimetal nanoparticles:Facile large-scale preparation and catalytic hydrogenation performance
文献摘要：
Non-noble bimetals have attracted extensive attention for their natural aboundance and low cost,but it remains a big challenge to design and synthesize novel supported non-noble bimetal nanocatalyst in a controllable and high-efficient manner.Herein,a novel hollow spherical supported non-noble bimetal nanocatalyst with porous carbon shell as the continuous matrix and Cu/Co bimetal nanoparticles as the dispersion phase is successfully fabricated by a convenient strategy involving spray drying and subse-quent heat treatment.The morphology and microstructure depend catalyst activity of the hollow spher-ical supported catalyst has been studied systematically.It is found that the heating temperature plays a critical role in determining the microstructure and catalytic performance of the products.With an opti-mal heating temperature of 600℃,the corresponding product exhibits the highest normalized reaction rate constant(kn)of 25.4 s-1 g-1 for catalytic reduction of 4-notrophenol,which can be attributed to the suitable synergism of the well-defined bimetal structure,combined effect of the two metallic phases and the metal-support interaction.This work provides an additional strategy for the simultaneous forma-tion of both the support and the active loading phase of supported non-noble bimetal nanocatalyst,and may shed some light on the high-efficiency synthesis of other supported heterostructure with various compositions and properties.
