Effect study of precursor concentration of ZnO crystals obtained by electrode position

Recent progress in the electrochemical deposition of ZnO nanowires: synthesis approaches and applications

“…For the templateless electrodeposition of ZnO nanowires and nanorods, the (002) preferred orientation is promoted at low concentrations of the precursor, high bath temperatures, moderate potentials, and short deposition times. For the hardtemplate electrodeposition of ZnO nanowires or nanorods, higher concentrations of the precursor can be used 38,39,43,[63][64][65][66][67][68] .…”

“…The optimal precursor concentrations for the templateless electrodeposition of ZnO nanowires and nanorods are a saturated solution for molecular oxygen, 2-5 mM for nitrate ions, and 2-10 mM for hydrogen peroxide 38,39,43,63,65,66,[68][69][70] .…”

“…The increase of [Zn 2+ ] provokes a decrease in nanowire density and an increase in nanowire diameter 38,39,43,63,65,66,[68][69][70][71][72][73] .…”

“…-The increase of [Zn 2+ ] translates to a wider diameter distribution 38,39,43,63,65,66,[68][69][70][72][73][74] .…”

“…-High concentrations of [Zn 2+ ] (i.e., >10 mM) are not suitable for the templateless electrodeposition of ZnO nanowires or nanorods 38,39,43,63,65,66,[68][69][70][72][73][74] .…”
