The activated carbons used for the characterizations were
prepared under the following conditions: microwave power
350 W, radiation time 20min and phosphoric acid/carbon 1:1 for microwave activation; temperature 600 ◦C, heating rate 10 ◦C/min,
phosphoric acid/carbon 1:1 and activation time 60min for thermal
activation. The bamboo precursor was milled into powder for its
FTIR and XPS analysis.
