Materials Data on Re3(SCl)7 by Materials Project

Abstract

Re3(SCl)7 crystallizes in the trigonal P31c space group. The structure is two-dimensional and consists of two Re3(SCl)7 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Re7+ sites. In the first Re7+ site, Re7+ is bonded to five S2- and two Cl1- atoms to form distorted face-sharing ReS5Cl2 pentagonal bipyramids. There are a spread of Re–S bond distances ranging from 2.36–2.47 Å. Both Re–Cl bond lengths are 2.39 Å. In the second Re7+ site, Re7+ is bonded to five S2- and two Cl1- atoms to form distorted face-sharing ReS5Cl2 pentagonal bipyramids. There are a spread of Re–S bond distances ranging from 2.37–2.46 Å. There are one shorter (2.37 Å) and one longer (2.43 Å) Re–Cl bond lengths. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Re7+ and one S2- atom. The S–S bond length is 2.07 Å. In the second S2- site, S2- is bonded in a 4-coordinate geometry to two equivalent Re7+ atoms. In the third S2- site, S2- is bonded in a 7-coordinate geometry to two equivalent Re7+ and one Cl1- atom. The S–Cl bond length is 2.71 Å. In the fourth S2- site, S2- is bonded in a 7-coordinate geometry to two equivalent Re7+, one S2-, and four Cl1- atoms. There are a spread of S–Cl bond distances ranging from 2.71–3.60 Å. In the fifth S2- site, S2- is bonded in a 9-coordinate geometry to three equivalent Re7+ atoms. In the sixth S2- site, S2- is bonded in a 6-coordinate geometry to three equivalent Re7+ atoms. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Re7+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Re7+ and two equivalent S2- atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Re7+ atom. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Re7+ and one S2- atom. In the fifth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent S2- atoms. In the sixth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent S2- 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.
