The requisite papers by Chueh and Haile that motivate the use of ceria for redox: \cite{Chueh_2010} \cite{Chueh_2010a}  \item   These peoples modeled an entire reactor setup of ceria in a falling particle configuration: \cite{Oles_2015}. Not surprisingly, they found that the efficiency was low because the ceria particles do not absorb well. They go on to say that they must instead reflect well, which is not really so---the radiation goes right through!  Andrew S. Oles, Gregory S. Jackson. Modeling of a concentrated-solar falling-particle receiver for ceria reduction. Solar Energy 122, 126–147 (2015).  \end{itemize}
