A biochar-modified carbon paste electrode

TURKISH JOURNAL OF CHEMISTRY, 2017
The present work examined the use of biochar derived from tea waste as a novel electrode material. For the fabrication of the biochar electrode, suitable amounts of biochar and graphite were mixed with mineral oil for the first time. The electrochemical performance of the biochar-modified carbon paste electrode (BCPE) was measured by various cyclic ...
