Highly Efficient Ni–Co Alloy Catalyst Fabricated by a Multivariate CoNiMgZn-MOF Template for the Cascade Reaction of Nitroarenes With Alcohols
A porous carbon/MgO composite–supported CoNi alloy catalyst (denoted as CoNi@Zn/MC) was synthesized via a multivariate metal–organic framework (MTV-MOF) pyrolysis strategy. The catalyst, derived from Zn-doped CoNiMgZn-MOF precursors, demonstrated exceptional performance in the tandem hydrogenation–alkylation of nitroarenes with diverse alcohols. Comparative studies revealed that CoNi@Zn/MC achieved 100% selectivity for N-phenylbenzylamine, significantly outperforming the Zn-free CoNi/MC counterpart (80.2% selectivity). The incorporation of Zn2+ ions in the MOF precursors enhanced the reduction efficiency and dispersion of Co/Ni species during pyrolysis, as evidenced by HAADF-STEM and XRD analyses. Notably, CoNi@Zn/MC exhibited robust magnetic recyclability, maintaining full catalytic activity over seven consecutive cycles. This work provides a generalized template strategy for designing high-efficiency alloy catalysts for tandem reactions.
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
