a Schematic images comparing catalyst fabrication processes. b SEM micrograph of corresponding catalysts with La0.52Ca0.28Ni0.06Ti0.9O3 fibres. I. LCNT fibres reduced at 800 oC for 4 h in 5% H2/Ar (inset: size distribution of Ni particles), II. Pt deposited on LCNT fibres and treated at 400 oC in air to decompose nitrates, III. LCNT-Pt fibres reduced 600 oC for 4 h in 5% H2/Ar. c Thermogravimetric analysis plot of weight as a function of temperature step and (d) Temperature programmed reduction profiles of LCNT and Pt deposited LCNT fibres.
