Various metal ions with different valence states (Mg2+ , Al3+ Ca2+ Ti4+ Mn2+ Fe3+ Ni2+ Zn2+ Pb2+ Ba2+ Ce4+ ) are successfully confined in quasi-microcube shaped cobalt benzimidazole frameworks using a space-confined synthesis strategy. More importantly, series of derived carbon materials that confine obtained by high-temperature pyrolysis. Interestingly, the exhibited electric double-layer and pseudocapacitance properties because presence various states. Moreover, additional within may create new phases, which can accelerate Na+ insertion/extraction thus increase electrochemical adsorption. Density functional theory results showed Ti exhibit enhanced resulting from characteristic anatase crystalline phases TiO2 . The Ti-containing have an impressive desalination capacity (62.8 mg g-1 capacitive deionization (CDI) applications high cycling stability. This work provides facile synthetic strategy for confinement metal-organic supports further development seawater CDI.

Plastic waste has become a serious environmental issue and attracted increasing attention. Various treatment technologies have been developed for the remediation of this waste, including degradation, recycling upcycling, transformation to value-added products extensively studied. Transitioning plastic into carbon-based functional materials is especially attractive because practical applications wastes derived carbon (PWCMs) in field green energy sustainable practices. Herein, recent advances preparation PWCMs are systematically reviewed. Thermal methods synthesizing from summarized, anoxic pyrolysis, catalytic pressure carbonization techniques, flash Joule heating microwave conversion. The PWCMs-based composites storage production (such as batteries, supercapacitors water-splitting systems) concepts (pollutant adsorption/degradation, solar evaporation CO2 capture) detailed, with an emphasis on property-performance correlation. potential future development also examined. This review meant provide insights advanced stimulate upcycling waste.

Abstract Lithium−sulfur batteries (LSBs) are regarded as one of the most promising candidates for energy storage devices. However, severe shuttling effect soluble polysulfides (PSs) limits its further application. Metal−organic frameworks (MOFs) have emerged a new kind sulfur host their talents in confining and trapping PSs. shuttle has not been fully stressed significant drawback MOFs that leads to sluggish redox kinetics, resulting low specific capacity short lifetime, especially at high loading. In this work, MOF‐sulfur copolymer (CNT@UiO‐66‐V‐S) is elaborated by copolymerization with vinyl functionalized MOFs. Systematic electrochemical experiments situ Raman spectroscopy analysis indicate cathode exhibits radical reaction mechanism can accelerates LiPSs conversion. The CNT@UiO‐66‐V‐S delivers over 100% improved discharge lowers decay rate both (5.6 mg cm –2 ) loadings compared physically mixed MOF/S cathode. strategy provides solution promoting kinetics tackling effect, expected inspire design advanced hosts applied high‐performance LSBs.
