Materials Data on Fe2TeWC10SeO10 by Materials Project

Abstract

WFe2C6TeSeO6(CO)4 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of eight formaldehyde molecules and one WFe2C6TeSeO6 ribbon oriented in the (1, 0, 0) direction. In the WFe2C6TeSeO6 ribbon, W2+ is bonded in a 2-coordinate geometry to one Te2- and one Se2- atom. The W–Te bond length is 2.79 Å. The W–Se bond length is 2.61 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded in a 5-coordinate geometry to three C+1.60+, one Te2-, and one Se2- atom. There is one shorter (1.77 Å) and two longer (1.81 Å) Fe–C bond length. The Fe–Te bond length is 2.57 Å. The Fe–Se bond length is 2.42 Å. In the second Fe3+ site, Fe3+ is bonded in a 5-coordinate geometry to three C+1.60+, one Te2-, and one Se2- atom. There is one shorter (1.77 Å) and two longer (1.80 Å) Fe–C bond length. The Fe–Te bond length is 2.57 Å. The Fe–Se bond length is 2.43 Å. There are six inequivalent C+1.60+ sites. In the first C+1.60+ site, C+1.60+ is bonded in a distorted single-bond geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the second C+1.60+ site, C+1.60+ is bonded in a linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the third C+1.60+ site, C+1.60+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the fourth C+1.60+ site, C+1.60+ is bonded in a distorted linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the fifth C+1.60+ site, C+1.60+ is bonded in a distorted single-bond geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. In the sixth C+1.60+ site, C+1.60+ is bonded in a linear geometry to one Fe3+ and one O2- atom. The C–O bond length is 1.16 Å. Te2- is bonded in a 2-coordinate geometry to one W2+, two Fe3+, and three O2- atoms. There are a spread of Te–O bond distances ranging from 3.43–3.72 Å. Se2- is bonded in a 2-coordinate geometry to one W2+ and two Fe3+ atoms. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ and one Te2- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ and one Te2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ and one Te2- atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one C+1.60+ 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.
