Abstract:
A self-enhanced photoelectrochemical copper ions sensor was constructed using an organic electron donor matrix with a Schottky heterostructure prepared from dopamine and single walled carbon nanohorns. The determination of Cu2+ with no additional electron donor solution, with high sensitivity and low background, provides new inspiration for the development of photoelectric sensing.
