Materials Data on UTa2S6Cl6O by Materials Project

Abstract

UTa2O(S2)3Cl6 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one UTa2O(S2)3Cl6 ribbon oriented in the (1, 0, 0) direction. U4+ is bonded in a 1-coordinate geometry to four S1-, one O2-, and four Cl1- atoms. There are a spread of U–S bond distances ranging from 2.85–2.96 Å. The U–O bond length is 2.32 Å. There are a spread of U–Cl bond distances ranging from 2.77–2.85 Å. There are two inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded in a 7-coordinate geometry to four S1-, one O2-, and two Cl1- atoms. There are a spread of Ta–S bond distances ranging from 2.45–2.59 Å. The Ta–O bond length is 2.02 Å. There are one shorter (2.32 Å) and one longer (2.35 Å) Ta–Cl bond lengths. In the second Ta5+ site, Ta5+ is bonded in a 7-coordinate geometry to four S1-, one O2-, and two Cl1- atoms. There are a spread of Ta–S bond distances ranging from 2.46–2.58 Å. The Ta–O bond length is 2.01 Å. There are one shorter (2.32 Å) and one longer (2.38 Å) Ta–Cl bond lengths. There are six inequivalent S1- sites. In the first S1- site, S1- is bonded in a 2-coordinate geometry to two Ta5+, one S1-, and one Cl1- atom. The S–S bond length is 2.08 Å. The S–Cl bond length is 3.17 Å. In the second S1- site, S1- is bonded in a 1-coordinate geometry to one U4+, one Ta5+, and one S1- atom. The S–S bond length is 2.08 Å. In the third S1- site, S1- is bonded in a 1-coordinate geometry to one U4+, one Ta5+, one S1-, and two Cl1- atoms. There are one shorter (3.28 Å) and one longer (3.60 Å) S–Cl bond lengths. In the fourth S1- site, S1- is bonded in a 1-coordinate geometry to one U4+ and one Ta5+ atom. In the fifth S1- site, S1- is bonded in a 1-coordinate geometry to one U4+ and one Ta5+ atom. In the sixth S1- site, S1- is bonded in a 2-coordinate geometry to two Ta5+ and one S1- atom. O2- is bonded in a trigonal non-coplanar geometry to one U4+ and two Ta5+ atoms. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent U4+ and one S1- atom. In the second Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Ta5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Ta5+ and two S1- atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted water-like geometry to two equivalent U4+ atoms. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Ta5+ atom.

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.
