Bimetal-organic-frameworks-derived yolk-shell-structured porous Co2P/ZnO@PC/CNTs hybrids for highly sensitive non-enzymatic detection of superoxide anion released from living cells

We report a general approach for the synthesis of yolk-shell-structured porous dicobalt phosphide/zinc oxide@porous carbon polyhedral/carbon nanotube hybrids (Co2P/ZnO@PC/CNTs) derived from bimetal-organic frameworks, and explore their potential utilization in the electrochemical sensing of superoxi...

Description
Summary:We report a general approach for the synthesis of yolk-shell-structured porous dicobalt phosphide/zinc oxide@porous carbon polyhedral/carbon nanotube hybrids (Co2P/ZnO@PC/CNTs) derived from bimetal-organic frameworks, and explore their potential utilization in the electrochemical sensing of superoxide anions. Beyond our expectation, the trace level of O2˙- released from living cells has also been successfully captured by our designed sensor. The presented strategy for the controlled design and synthesis of bimetal-organic frameworks-derived functional nanomaterials offers prospects of developing highly active electrocatalysts in non-enzyme sensors.
