研究目的
Investigating the role of Cu and Cu2O ratio for fabricating earth abundant cost effective nanocatalysts for OER, HER, and organic chemical transformation.
研究成果
Hybrid Cu-Cu2O@C materials exhibited stronger electrocatalytic activity compared to pure phases whereas pure Cu and Cu2O@C NPs displayed better catalytic activity for A3 coupling reaction. The present work investigated the role of Cu and Cu2O ratio for fabricating earth abundant cost effective nanocatalysts for OER, HER, and organic chemical transformation.

1：Experimental Design and Method Selection:
Hydrothermal synthesis of carbon encapsulated hybrid Cu-Cu2O NPs with different ratio of Cu and Cu2O using amino acid based multidendate phenolic chelating organic ligands.
2：Sample Selection and Data Sources:
Samples were synthesized using different amino acid based phenolic ligands.
3：List of Experimental Equipment and Materials:
Powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (HR-TEM), and electrochemical work station (CHI660E, Austin, Texas, USA).
4：Experimental Procedures and Operational Workflow:
Hydrothermal reaction of Cu(OAc)
5：H2O and phenolic chelating organic ligand at
1 ratio in water-ethanol (4:1) produced carbon encapsulated NPs.
6：Data Analysis Methods:
PXRD analysis confirmed the formation of pure phase as well as hybrid Cu-Cu2O NPs in the carbon matrix. XPS analysis confirmed the formation of pure phase and hybrid Cu-Cu2O NPs in the carbon. HR-TEM images revealed formation of polydispersed crystalline Cu and Cu2O NPs with featureless morphologies in the carbon matrix.
