Electrochemical and electrocatalytic studies of toluidine blue immobilized on a silica gel surface coated with niobium oxide
The electrochemical behavior of toluidine blue (TB) adsorbed on a silica surface modified with niobium oxide (SN) was investigated using a modified carbon paste electrode. The presence of SN gave the electrode high stability, avoiding the leaching out of the mediator from the electrode surface. The...
