Materials Data on Pr5S2N3Cl2 by Materials Project

Abstract

Pr5N3S2Cl2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are five inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 1-coordinate geometry to one N3-, two S2-, and four Cl1- atoms. The Pr–N bond length is 2.20 Å. There are one shorter (3.13 Å) and one longer (3.35 Å) Pr–S bond lengths. There are two shorter (2.85 Å) and two longer (2.92 Å) Pr–Cl bond lengths. In the second Pr3+ site, Pr3+ is bonded in a 3-coordinate geometry to three N3-, two equivalent S2-, and three Cl1- atoms. There are two shorter (2.39 Å) and one longer (2.45 Å) Pr–N bond lengths. Both Pr–S bond lengths are 3.26 Å. There are one shorter (3.11 Å) and two longer (3.29 Å) Pr–Cl bond lengths. In the third Pr3+ site, Pr3+ is bonded in a 6-coordinate geometry to two equivalent N3- and four S2- atoms. There are one shorter (2.35 Å) and one longer (2.40 Å) Pr–N bond lengths. There are two shorter (2.95 Å) and two longer (3.00 Å) Pr–S bond lengths. In the fourth Pr3+ site, Pr3+ is bonded in a 2-coordinate geometry to two equivalent N3-, four S2-, and one Cl1- atom. Both Pr–N bond lengths are 2.40 Å. There are a spread of Pr–S bond distances ranging from 2.89–3.33 Å. The Pr–Cl bond length is 2.93 Å. In the fifth Pr3+ site, Pr3+ is bonded to four N3- and three equivalent Cl1- atoms to form distorted edge-sharing PrN4Cl3 trigonal pyramids. There are a spread of Pr–N bond distances ranging from 2.33–2.44 Å. There are one shorter (3.26 Å) and two longer (3.43 Å) Pr–Cl bond lengths. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded to four Pr3+ atoms to form a mixture of edge and corner-sharing NPr4 tetrahedra. In the second N3- site, N3- is bonded to four Pr3+ atoms to form a mixture of edge and corner-sharing NPr4 trigonal pyramids. In the third N3- site, N3- is bonded to four Pr3+ atoms to form a mixture of distorted edge and corner-sharing NPr4 tetrahedra. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to six Pr3+ atoms. In the second S2- site, S2- is bonded in a 6-coordinate geometry to six Pr3+ and two equivalent Cl1- atoms. Both S–Cl bond lengths are 3.47 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 3-coordinate geometry to five Pr3+ and two equivalent S2- atoms. In the second Cl1- site, Cl1- is bonded in a 6-coordinate geometry to six Pr3+ atoms.

Cyclic moisture reactivation of calcium sorbents for long duration thermochemical energy storage

The transition to a flexible and reliable energy infrastructure, using electro-thermal energy generation technologies such as geothermal, concentrated solar power, and nuclear, usually demands simultaneous advancement of thermal energy storage (TES) to support on-demand electricity generation and industrial applications while mitigating the inherent intermittency of renewable energy sources and power outages from direct energy generation. Among TES technologies, thermochemical energy storage (TCES) based on calcium looping emerges as a compelling high-power energy storage candidate due to its high reaction enthalpy, compatibility with elevated operating temperatures, and abundance of low-cost materials. However, the long-term durability of calcium-based sorbents for TCES is hindered by surface sintering and particle aggregation, leading to performance degradation over repeated thermal cycles. This study explores a moisture hydration-based strategy to regenerate a degraded calcium sorbent and mitigate performance degradation for long duration TCES. The addition of moisture transforms calcium oxide into calcium hydroxide and produces intercalation water layers, associated with a regenerated surface area and reduced calcium oxide crystallite size. Both these effects are beneficial in restoring the sorbents' reactivity for carbonization. Additionally, an optimized hydration-assisted reactivation protocol balances the recovered energy storage capacity with heating penalty required for moisture removal from hydrated samples, resulting in an enhanced energy storage capacity up to 176% compared to benchmark sorbents that undergo cycling without reactivation after 60 cycles. In conclusion, these results highlight the potential of hydration-assisted reactivation to enhance the long-term performance of TCES, providing an effective pathway to advancing electro-thermal storage technologies.
