Soft templated mesoporous manganese oxide/carbon nanotube composites via interfacial surfactant assembly†
Abstract
A mesoporous manganese oxide/carbon nanotube (CNT) composite was successfully synthesized using cetyltrimethylammonium bromide as a protection layer to prevent the direct contact between CNT and MnO4− ions, a linking agent to interact with MnO4− ions and a structure-directing agent for the formation of mesoporous oxide. The observed improvement in electrochemical utilization of MnO2 was due to the synergetic effect of the mesoporous structure and CNTs, which enhanced the overall electronic and ionic conductivities.
