Highly dispersed silver imbedded into TiN submicrospheres for electrochemical detecting of hydrogen peroxide

Abstract We report the fabrication of silver nanoparticles evenly imbedded into TiN submicrospheres via one-pot solvothermal reaction and subsequent nitridation for electrochemical detecting of hydrogen peroxide. The precursor of TiO2 submicrospheres and high dispersion of silver nanoparticles are r...
