Abstract

CH2Cl2Sb6HO10Cl11 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four dichloromethane molecules and two Sb6HO10Cl11 clusters. In each Sb6HO10Cl11 cluster, there are six inequivalent Sb+4.33+ sites. In the first Sb+4.33+ site, Sb+4.33+ is bonded to four O2- and two Cl1- atoms to form a mixture of edge and corner-sharing SbCl2O4 octahedra. The corner-sharing octahedra tilt angles range from 45–54°. There are a spread of Sb–O bond distances ranging from 2.03–2.13 Å. Both Sb–Cl bond lengths are 2.34 Å. In the second Sb+4.33+ site, Sb+4.33+ is bonded to four O2- and two Cl1- atoms to form a mixture of edge and corner-sharing SbCl2O4 octahedra. The corner-sharing octahedra tilt angles range from 45–54°. There are a spread of Sb–O bond distances ranging from 2.02–2.13 Å. Both Sb–Cl bond lengths are 2.34 Å. In the third Sb+4.33+ site, Sb+4.33+ is bonded to four O2- and two Cl1- atoms to form distorted SbCl2O4 octahedra that share corners with two SbCl2O4 octahedra and edges with two SbClO5 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There are a spread of Sb–O bond distances ranging from 1.96–2.45 Å. There are one shorter (2.31 Å) and one longer (2.33 Å) Sb–Cl bond lengths. In the fourth Sb+4.33+ site, Sb+4.33+ is bonded to five O2- and one Cl1- atom to form a mixture of edge and corner-sharing SbClO5 octahedra. The corner-sharing octahedra tilt angles range from 48–54°. There are a spread of Sb–O bond distances ranging from 1.98–2.18 Å. The Sb–Cl bond length is 2.34 Å. In the fifth Sb+4.33+ site, Sb+4.33+ is bonded to four O2- and two Cl1- atoms to form distorted SbCl2O4 octahedra that share corners with two SbCl2O4 octahedra and edges with two SbClO5 octahedra. The corner-sharing octahedra tilt angles range from 45–51°. There are a spread of Sb–O bond distances ranging from 1.96–2.42 Å. There are one shorter (2.31 Å) and one longer (2.33 Å) Sb–Cl bond lengths. In the sixth Sb+4.33+ site, Sb+4.33+ is bonded to four O2- and two Cl1- atoms to form a mixture of distorted edge and corner-sharing SbCl2O4 octahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of Sb–O bond distances ranging from 1.97–2.22 Å. Both Sb–Cl bond lengths are 2.33 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sb+4.33+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sb+4.33+ and one H1+ atom. In the third O2- site, O2- is bonded in a water-like geometry to two Sb+4.33+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to two Sb+4.33+ atoms. In the fifth O2- site, O2- is bonded in a water-like geometry to two Sb+4.33+ atoms. In the sixth O2- site, O2- is bonded in a water-like geometry to two Sb+4.33+ atoms. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to three Sb+4.33+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to three Sb+4.33+ atoms. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to three Sb+4.33+ atoms. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to three Sb+4.33+ atoms. There are eleven inequivalent Cl1- sites.

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.
