Electrochemistry of undoped diamond nanoparticles: accessing surface redox states.


The electrochemical response of an electrode-immobilized layer of undoped, insulating diamond nanoparticles is reported, which we attribute to the oxidation and reduction of surface states. The potentials of these surface states are pH-dependent; moreover they are able to interact with solution redox species. The voltammetric response of redox couples Fe(CN… (More)
