Thermochemical water-splitting reactor set-up for H2 generation .
SEM images of SnxFeyOz powders prepared with Sn:Fe weight ratio of 1:2 wt/wt and calcined rapidly upto 900 °C and quenched in (a) air or (b) N2 environment.
Transient H2 profiles obtained during four thermochemical cycles where water-splitting and regeneration steps were performed at 900 °C and 1100 °C using SF-1 and SF-2 materials.
XRD patterns of (a) SF-1 as-prepared and reacted and (b) SF-2 as-prepared and reacted (the reacted refers to the material that underwent four thermochemical cycles).
A summary of different products observed at the end of calcination and thermochemical cycles.
Comparison of H2 generation ability of SF-1 and SF-2 materials during four thermochemical cycles where water-splitting and regeneration steps were performed 900 °C and 1100 °C, respectively.
SEM images of reacted (a) SF-1 and (b) SF-2 materials obtained after performing four consecutive thermochemical cycles in the temperature range of 900 °C to 1100 °C.
