Materials Data on P3Ru by Materials Project

Abstract

RuP3 is Hausmannite-like structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ru2+ sites. In the first Ru2+ site, Ru2+ is bonded to six P+0.67- atoms to form RuP6 octahedra that share corners with five equivalent RuP6 octahedra, corners with nine PP3Ru tetrahedra, and edges with two equivalent RuP6 octahedra. The corner-sharing octahedra tilt angles range from 41–63°. There are a spread of Ru–P bond distances ranging from 2.36–2.42 Å. In the second Ru2+ site, Ru2+ is bonded to six P+0.67- atoms to form RuP6 octahedra that share corners with five equivalent RuP6 octahedra, corners with eleven PPRu3 tetrahedra, and an edgeedge with one RuP6 octahedra. The corner-sharing octahedra tilt angles range from 41–63°. There are a spread of Ru–P bond distances ranging from 2.31–2.42 Å. There are six inequivalent P+0.67- sites. In the first P+0.67- site, P+0.67- is bonded to three Ru2+ and one P+0.67- atom to form distorted PPRu3 tetrahedra that share a cornercorner with one RuP6 octahedra, corners with fifteen PP3Ru tetrahedra, and an edgeedge with one PPRu3 tetrahedra. The corner-sharing octahedral tilt angles are 70°. The P–P bond length is 2.22 Å. In the second P+0.67- site, P+0.67- is bonded to one Ru2+ and three P+0.67- atoms to form distorted PP3Ru tetrahedra that share corners with five RuP6 octahedra and corners with nine PPRu3 tetrahedra. The corner-sharing octahedra tilt angles range from 58–72°. There are a spread of P–P bond distances ranging from 2.21–2.24 Å. In the third P+0.67- site, P+0.67- is bonded to one Ru2+ and three P+0.67- atoms to form PP3Ru tetrahedra that share corners with six RuP6 octahedra and corners with eight PPRu3 tetrahedra. The corner-sharing octahedra tilt angles range from 54–82°. The P–P bond length is 2.22 Å. In the fourth P+0.67- site, P+0.67- is bonded to three Ru2+ and one P+0.67- atom to form PPRu3 tetrahedra that share a cornercorner with one RuP6 octahedra, corners with fifteen PPRu3 tetrahedra, and an edgeedge with one PPRu3 tetrahedra. The corner-sharing octahedral tilt angles are 60°. In the fifth P+0.67- site, P+0.67- is bonded to two Ru2+ and two P+0.67- atoms to form PP2Ru2 tetrahedra that share corners with four RuP6 octahedra and corners with twelve PPRu3 tetrahedra. The corner-sharing octahedra tilt angles range from 66–77°. There are one shorter (2.20 Å) and one longer (2.22 Å) P–P bond lengths. In the sixth P+0.67- site, P+0.67- is bonded to two equivalent Ru2+ and two P+0.67- atoms to form PP2Ru2 tetrahedra that share corners with three RuP6 octahedra, corners with eleven PPRu3 tetrahedra, and an edgeedge with one PP2Ru2 tetrahedra. The corner-sharing octahedra tilt angles range from 68–73°.

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.
