Abstract Supported polyethyleneimine (PEI) adsorbent is one of the most promising commercial direct air capture (DAC) adsorbents with a long research history since 2002. Although great efforts have been input, there are still limited improvements for this material in its CO 2 capacity and adsorption kinetics under ultradilute conditions. PEI also suffers significantly reduced capacities when working at sub‐ambient temperatures. This study reports that mixing diethanolamine (DEA) into...
Abstract The utilization of supported amines as adsorbents in direct air capture (DAC) has been demonstrated to be a promising strategy for the reduction CO 2 emissions. To improve performance amine‐based adsorbents, incorporation additives widely adopted. In present study, we conduct comprehensive comparison seven on tetraethylenepentamine‐impregnated mesoporous silica representative adsorbent. results indicate that minor molecular weight with hydroxyl groups show improved...
Abstract The immature design theory of electrolytes limits their targeted solvation structure formation and application in batteries. Here, based on the precondition that an electrolyte or solution is a system at thermodynamic equilibrium state, we try to develop guide design. In this theory, competitive between cation-solvent interaction cation-anion interaction, enthalpy entropy, are two key points determining solute dissolution various structures. Using essential principle all recently...
A Mn–Ni(OH) 2 @1T-MoS heterostructure with lattice-matched interfaces was fabricated, thereby boosting conductivity and delivering 244.2 mA h g −1 capacity a good rate capability of 51.4% at 12 .
Abstract Lithium−sulfur (Li−S) batteries are promising candidates for next‐generation energy storage systems. However, unsurpassed challenges including the shuttle effect and Li dendrite growth still faced marketization. Herein, La 2 Zr O 7‐ x (OV‐LZO) nanotubes with surface oxygen vacancies were fabricated to serve as Janus separator coatings Li−S batteries. The overlapping OV‐LZO construct an efficient lithium polysulfides adsorption catalysis network at interface of cathode/separator a +...
Lithium metal is an ideal electrode material for future rechargeable batteries. However, dendrite formation and unstable solid electrolyte interphase film lead to safety concerns poor Coulombic efficiency (CE). LiNO3 significantly improves the performance of lithium anode in ester electrolytes but its use restricted by low solubility. To increase content cell, a poly-(vinyl carbonate) organogel interlayer containing dissociated (LNO-PVC) placed between cathode anode. The effectively...
The development of efficient adsorbents is one the key technologies for direct air capture (DAC). Herein, a facile and scalable method to synthesize amine-functionalized layered double hydroxides (LDHs) as DAC presented. Specifically, ultrafine exfoliated Mg2Al–CO3 LDH nanosheets were generated within 2 min via rapid nucleation aging followed by organic solvent treatment, they remained on powders after vacuum drying. well-dispersed grafted with high density monolayered aminosilane (5.51 mmol...
