Fig. 1: Schematic illustration of the synthesis of CuNa-CF catalyst.

The dual metal site catalyst with transition Cu atom and main-group Na-containing functional group encapsulated in the flexible carbon nanofibers (CuNa-CF) was synthesized by using pyrolysis followed solution blow spinning technology. Uniformly dispersed chlorophyllin sodium copper complex-polyacrylonitrile (CSCC-PAN) membrane can be scalable produced by using solution blow spinning strategy.
