Abstract

High temperature looping cycles can be used to produce hydrogen or capture CO₂ from power stations, though sintering of absorbents is frequently a problem, reducing reactivity. In this work we develop materials, in which the crystal structure and volume of polymorphic materials change with temperature, as active spacers to reduce sintering.
