Materials Data on PCSN3O2 by Materials Project

Abstract

CPN3SO2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two CPN3SO2 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a 1-coordinate geometry to three N1- atoms. There are a spread of C–N bond distances ranging from 1.21–1.46 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three N1- atoms. There are a spread of C–N bond distances ranging from 1.31–1.39 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one S2- and three O2- atoms to form distorted corner-sharing PSO3 tetrahedra. The P–S bond length is 2.19 Å. There are a spread of P–O bond distances ranging from 1.46–1.64 Å. In the second P5+ site, P5+ is bonded to one S2- and three O2- atoms to form distorted corner-sharing PSO3 tetrahedra. The P–S bond length is 2.11 Å. There is one shorter (1.46 Å) and two longer (1.63 Å) P–O bond length. There are six inequivalent N1- sites. In the first N1- site, N1- is bonded in a 1-coordinate geometry to one C4+, one N1-, and one S2- atom. The N–N bond length is 1.26 Å. The N–S bond length is 3.28 Å. In the second N1- site, N1- is bonded in a distorted bent 120 degrees geometry to one C4+ and one S2- atom. The N–S bond length is 1.65 Å. In the third N1- site, N1- is bonded in a distorted bent 150 degrees geometry to one C4+ and one S2- atom. The N–S bond length is 1.59 Å. In the fourth N1- site, N1- is bonded in a distorted single-bond geometry to one C4+ atom. In the fifth N1- site, N1- is bonded in a 1-coordinate geometry to one C4+ and one N1- atom. In the sixth N1- site, N1- is bonded in a single-bond geometry to one C4+ atom. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a distorted bent 120 degrees geometry to one P5+ and two N1- atoms. In the second S2- site, S2- is bonded in a distorted water-like geometry to one P5+ and one N1- atom. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ 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.
