Materials Data on PrGa3Co10 by Materials Project

Abstract

PrCo10Ga3 crystallizes in the orthorhombic Fmm2 space group. The structure is three-dimensional. Pr is bonded in a 10-coordinate geometry to eighteen Co and six Ga atoms. There are a spread of Pr–Co bond distances ranging from 3.27–3.40 Å. There are a spread of Pr–Ga bond distances ranging from 3.27–3.30 Å. There are nine inequivalent Co sites. In the first Co site, Co is bonded to ten Co and two equivalent Ga atoms to form face-sharing CoGa2Co10 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.36–2.44 Å. Both Co–Ga bond lengths are 2.47 Å. In the second Co site, Co is bonded to eight Co and four Ga atoms to form a mixture of corner and face-sharing CoGa4Co8 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.44–2.49 Å. All Co–Ga bond lengths are 2.47 Å. In the third Co site, Co is bonded in a 12-coordinate geometry to two equivalent Pr, seven Co, and three Ga atoms. There are a spread of Co–Co bond distances ranging from 2.38–2.77 Å. There are one shorter (2.45 Å) and two longer (2.49 Å) Co–Ga bond lengths. In the fourth Co site, Co is bonded to two equivalent Pr, eight Co, and two Ga atoms to form distorted CoPr2Ga2Co8 cuboctahedra that share corners with five CoGa4Co8 cuboctahedra and faces with five CoGa2Co10 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.44–2.53 Å. There are one shorter (2.44 Å) and one longer (2.46 Å) Co–Ga bond lengths. In the fifth Co site, Co is bonded in a 12-coordinate geometry to two equivalent Pr, seven Co, and three Ga atoms. There are a spread of Co–Co bond distances ranging from 2.43–2.70 Å. There are one shorter (2.40 Å) and two longer (2.49 Å) Co–Ga bond lengths. In the sixth Co site, Co is bonded in a 12-coordinate geometry to two equivalent Pr, six Co, and four Ga atoms. There are one shorter (2.56 Å) and two longer (2.58 Å) Co–Co bond lengths. There are two shorter (2.41 Å) and two longer (2.47 Å) Co–Ga bond lengths. In the seventh Co site, Co is bonded in a 12-coordinate geometry to two equivalent Pr, seven Co, and three Ga atoms. There are a spread of Co–Co bond distances ranging from 2.35–2.71 Å. There are a spread of Co–Ga bond distances ranging from 2.53–2.58 Å. In the eighth Co site, Co is bonded in a 12-coordinate geometry to two equivalent Pr, seven Co, and three Ga atoms. There are one shorter (2.50 Å) and one longer (2.66 Å) Co–Co bond lengths. There are a spread of Co–Ga bond distances ranging from 2.52–2.61 Å. In the ninth Co site, Co is bonded to two equivalent Pr, nine Co, and one Ga atom to form a mixture of distorted corner and face-sharing CoPr2GaCo9 cuboctahedra. The Co–Ga bond length is 2.79 Å. There are three inequivalent Ga sites. In the first Ga site, Ga is bonded in a 11-coordinate geometry to two equivalent Pr and nine Co atoms. In the second Ga site, Ga is bonded in a 12-coordinate geometry to two equivalent Pr and ten Co atoms. In the third Ga site, Ga is bonded in a 11-coordinate geometry to two equivalent Pr and nine Co 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.
