Materials Data on Mn3In2Sb3O14 by Materials Project

Abstract

Mn3In2Sb3O14 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Mn+2.33+ sites. In the first Mn+2.33+ site, Mn+2.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six SbO6 octahedra and edges with four equivalent InO8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 50°. There is four shorter (1.97 Å) and two longer (1.98 Å) Mn–O bond length. In the second Mn+2.33+ site, Mn+2.33+ is bonded to eight O2- atoms to form distorted MnO8 hexagonal bipyramids that share edges with four equivalent InO8 hexagonal bipyramids and edges with six SbO6 octahedra. There are a spread of Mn–O bond distances ranging from 2.19–2.52 Å. In the third Mn+2.33+ site, Mn+2.33+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Mn–O bond distances ranging from 2.27–2.52 Å. In3+ is bonded to eight O2- atoms to form distorted InO8 hexagonal bipyramids that share edges with two equivalent MnO8 hexagonal bipyramids, edges with two equivalent InO8 hexagonal bipyramids, edges with two equivalent MnO6 octahedra, and edges with four SbO6 octahedra. There are a spread of In–O bond distances ranging from 2.19–2.50 Å. There are two inequivalent Sb5+ sites. In the first Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with four equivalent SbO6 octahedra, edges with two equivalent MnO8 hexagonal bipyramids, and edges with four equivalent InO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 49–50°. There is two shorter (1.97 Å) and four longer (2.00 Å) Sb–O bond length. In the second Sb5+ site, Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with four SbO6 octahedra, edges with two equivalent MnO8 hexagonal bipyramids, and edges with two equivalent InO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 49–50°. There are a spread of Sb–O bond distances ranging from 1.97–2.01 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two Mn+2.33+ and two equivalent In3+ atoms to form corner-sharing OMn2In2 tetrahedra. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Mn+2.33+, two equivalent In3+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Mn+2.33+ and two equivalent Sb5+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Mn+2.33+, one In3+, and one Sb5+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Mn+2.33+, one In3+, and two Sb5+ 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.
