| Description |
High-surface area and well-ordered mesoporous Fe incorporated SBA-15 (Fe-SBA-15), FeeCr
incorporated SBA-15 (FeeCr-SBA-15) and Cr incorporated SBA-15 (Cr-SBA-15) catalysts are synthesized
following a controlled post synthesis grafting process. The activities of all the catalysts are tested
systematically and quantitatively towards the production of carbon nanotubes (CNTs) by chemical
vapour deposition. In order to obtain CNTs with high quality and quantity, the parameters like
temperature, reaction time and gas flow rate are optimized. Under optimum conditions, the FeeCr-SBA-
15 catalyst is produced with high yield and uniform diameter of CNTs. The transmission electron
microscopy result reveals high purity and well-graphitized structure of CNTs. The synthesized CNTs are
used as counter electrode material for dye-sensitized solar cells (DSSCs). The CNTs based counter
electrode shows good chemical stability, lower charge-transfer resistance and higher electrocatalytic
activity towards I3
�/I� redox reaction than that of platinum (Pt) counter electrode. The energy conversion
efficiency of the CNTs counter electrode based DSSCs reaches 8.86% under irradiation with a simulated
solar light intensity of 100mWcm�2. The results prove that CNTs are one of the suitable candidates for Pt
free counter electrode for DSSCs
