Synthesis and electrochemical properties of carbon microtubes by a simple in situ template method

Direct synthesis of carbon-based microtubes by hydrothermal carbonization of microorganism cells

“…Recent studies also showed that CMTs had a great potential in serving as a mesoscale bridge from nano to bulk materials [7,8]. However, unlike CNTs, the synthetic methods of CMTs have not been fully investigated and most of the synthesis processes are complex, time consuming, and energy intensive [9].…”
