Abstract The increasing energy demands of society today have led to the pursuit alternative storage systems that can fulfil rigorous requirements like cost‐effectiveness and high capacities. Based fundamentally on earth‐abundant sodium sulfur, room‐temperature sodium–sulfur batteries are a promising solution in applications where existing lithium‐ion technology remains less economically viable, particularly large‐scale stationary such as grid‐level storage. Here, key challenges field first highlighted, followed by comprehensive analyses accessible strategies overcome them, starting from engineering anode–electrolyte interface both liquid solid electrolytes. Recently reported polymer solid‐state electrolytes also surveyed. Thereafter, core principles guiding use‐inspired design cathode architectures, covering spectrum elemental sulfur polysulfide cathodes, emerging host structures, covalent composites focused upon. Future prospects explored, with insights into other alkali‐metal beyond batteries, potassium–sulfur battery. Finally conclusion is provided outlining research directions necessary attain devices, potential solutions issues concerning production, so ultimately realize widespread deployment practical systems.

Three-dimensional (3D) covalent organic frameworks (COFs) are rare because there is a limited choice of building blocks that offer multiple reactive sites in polyhedral geometry. Here, we synthesized an cage molecule (Cage-6-NH2) was used as triangular prism node to yield the first cage-based 3D COF, 3D-CageCOF-1. This COF adopts unreported 2-fold interpenetrated acs topology and exhibits reversible dynamic behavior, switching between small-pore (sp) structure large-pore (lp) structure. It also shows high CO2 uptake captures water at low humidity (<40%). demonstrates potential for expanding structural complexity COFs by using cages units.

Achieving more than a two-electron photochemical CO2 reduction process using metal-free system is quite exciting and challenging, as it needs proper channeling of electrons. In the present study, we report rational design synthesis redox-active conjugated microporous polymer (CMP), TPA-PQ, by assimilating an electron donor, tris(4-ethynylphenyl)amine (TPA), with acceptor, phenanthraquinone (PQ). The TPA-PQ shows intramolecular charge-transfer (ICT)-assisted catalytic activity for visible-light-driven photoreduction to CH4 (yield = 32.2 mmol g–1) impressive rate (2.15 h–1 high selectivity (>97%). Mechanistic analysis based on experimental results, in situ DRIFTS, computational studies reveals that potential catalyzing was energetically driven photoactivated ICT upon surface adsorption CO2, wherein adjacent keto groups PQ unit play pivotal role. critical role stimulating photocatalysis further illustrated synthesizing another CMP (TEB-PQ), bearing triethynylbenzene (TEB) PQ, 8-fold lesser toward 4.4 compared TPA-PQ. results demonstrate novel concept efficient, sustainable, recyclable robust organic photocatalyst.
