Materials Data on NaZr2SN2Cl by Materials Project

Abstract

NaZr2N2SCl crystallizes in the trigonal R3m space group. The structure is three-dimensional. Na1+ is bonded to three equivalent S2- and three equivalent Cl1- atoms to form NaS3Cl3 octahedra that share corners with three equivalent ZrN4Cl3 trigonal pyramids, edges with six equivalent NaS3Cl3 octahedra, and edges with three equivalent ZrN4Cl3 trigonal pyramids. All Na–S bond lengths are 2.76 Å. All Na–Cl bond lengths are 2.84 Å. There are two inequivalent Zr4+ sites. In the first Zr4+ site, Zr4+ is bonded to four N3- and three equivalent Cl1- atoms to form distorted ZrN4Cl3 trigonal pyramids that share corners with three equivalent NaS3Cl3 octahedra, edges with three equivalent NaS3Cl3 octahedra, and edges with six equivalent ZrN4Cl3 trigonal pyramids. The corner-sharing octahedral tilt angles are 3°. There are one shorter (2.07 Å) and three longer (2.15 Å) Zr–N bond lengths. All Zr–Cl bond lengths are 3.01 Å. In the second Zr4+ site, Zr4+ is bonded in a 7-coordinate geometry to four N3- and three equivalent S2- atoms. There are three shorter (2.20 Å) and one longer (2.34 Å) Zr–N bond lengths. All Zr–S bond lengths are 2.73 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to four Zr4+ atoms to form NZr4 tetrahedra that share corners with three equivalent SNa3Zr3 octahedra, corners with six equivalent NZr4 tetrahedra, edges with three equivalent SNa3Zr3 octahedra, and edges with three equivalent NZr4 trigonal pyramids. The corner-sharing octahedral tilt angles are 24°. In the second N3- site, N3- is bonded to four Zr4+ atoms to form distorted NZr4 trigonal pyramids that share corners with three equivalent SNa3Zr3 octahedra, corners with six equivalent NZr4 trigonal pyramids, and edges with three equivalent NZr4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. S2- is bonded to three equivalent Na1+ and three equivalent Zr4+ atoms to form distorted SNa3Zr3 octahedra that share corners with three equivalent NZr4 tetrahedra, corners with three equivalent NZr4 trigonal pyramids, edges with six equivalent SNa3Zr3 octahedra, and edges with three equivalent NZr4 tetrahedra. Cl1- is bonded in a 6-coordinate geometry to three equivalent Na1+ and three equivalent Zr4+ 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.
