Materials Data on ZnGaNO by Materials Project

Abstract

ZnGaNO is Stannite-like structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are four inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with three equivalent ZnNO3 tetrahedra and corners with nine GaN2O2 tetrahedra. There are one shorter (2.02 Å) and three longer (2.05 Å) Zn–O bond lengths. In the second Zn2+ site, Zn2+ is bonded to one N3- and three O2- atoms to form ZnNO3 tetrahedra that share corners with five GaNO3 tetrahedra and corners with seven ZnO4 tetrahedra. The Zn–N bond length is 1.91 Å. There are two shorter (2.00 Å) and one longer (2.18 Å) Zn–O bond lengths. In the third Zn2+ site, Zn2+ is bonded to two equivalent N3- and two O2- atoms to form ZnN2O2 tetrahedra that share corners with five GaNO3 tetrahedra and corners with seven ZnNO3 tetrahedra. Both Zn–N bond lengths are 1.98 Å. There are one shorter (1.99 Å) and one longer (2.20 Å) Zn–O bond lengths. In the fourth Zn2+ site, Zn2+ is bonded to three equivalent N3- and one O2- atom to form ZnN3O tetrahedra that share corners with three equivalent ZnN2O2 tetrahedra and corners with nine GaN3O tetrahedra. All Zn–N bond lengths are 2.06 Å. The Zn–O bond length is 2.02 Å. There are four inequivalent Ga3+ sites.

There is three shorter (1.94 Å) and one longer (1.97 Å) Ga–N bond length. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded to three equivalent Zn2+ and one Ga3+ atom to form NZn3Ga tetrahedra that share corners with three equivalent NZn2Ga2 tetrahedra and corners with nine OZn3Ga tetrahedra. In the second N3- site, N3- is bonded to two equivalent Zn2+ and two Ga3+ atoms to form NZn2Ga2 tetrahedra that share corners with five OZn3Ga tetrahedra and corners with seven NZn3Ga tetrahedra. In the third N3- site, N3- is bonded to one Zn2+ and three Ga3+ atoms to form NZnGa3 tetrahedra that share corners with five OZn2Ga2 tetrahedra and corners with seven NZn2Ga2 tetrahedra. In the fourth N3- site, N3- is bonded to four Ga3+ atoms to form NGa4 tetrahedra that share corners with three equivalent NZnGa3 tetrahedra and corners with nine OZn3Ga tetrahedra.

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.
