ConspectusThe rising levels of atmospheric CO2 and their resulting impacts on the climate have necessitated urgent development effective carbon capture technologies. Electrochemical systems emerged as a potential alternative to conventional thermal based amine solutions due modularity, energy efficiency, lower environmental impact. Among these, aqueous electrochemical pH swing that capitalize dependence dissolved inorganic (CO2/HCO3–/CO32–) speciation release are particular interest they can be flexible in system design range potentials used well being environmentally benign. In this Account, we present our recent findings swing-based using redox-active materials, paving way toward sustainable solution for mitigating emissions.In first section, discuss utilization molecular organic materials by method. This configuration involves homogeneous electrolytes containing compounds combined with inert carbon-based electrodes. We oxygen-insensitive neutral red (NR)-based systems. Notably, discovery 1-aminopyridinium (1-AP) an electrochemically reversible compound enables efficient swing, leading impressive electron 1.25 mol per mole electrons. Additionally, explore red/leuconeutral (NR/NRH2) redox system, which demonstrates applicability direct air (DAC) ambient feed gas.The second section focuses nanomaterials electrodes capture. configuration, employ inducing swings without interrupting other ionic species, except protons. Specifically, effectiveness manganese oxide (MnO2) achieving selective removal from simulated flue gas. then demonstrate bismuth/silver (Bi/BiOCl, Ag/AgCl) nanoparticle electrode sodium-insensitive extracting (DIC) seawater high efficiency.Overall, these advances offer promising preliminary combating change capturing dilute sources such gas enabling ocean water. While demonstrated efficiency benefits represent only beginning research journey. Further optimization currently underway strive unlock full large-scale implementation, carbon-neutral future.

The utilization of carbonic anhydrases (CAs) for CO2 capture aligns with the principles environmental sustainability. However, there is an urgent need to minimize cost CA purification while improving their performance in harsh environments. A novel strategy was proposed solve above problems by employing ferritin-tagged variant (DvCA8.0-F). achieved low-speed centrifugation, yielding 92% activity recovery and 95% purity. After 14 weeks incubation a 50% MDEA solution at 50 °C, DvCA8.0-F maintained nearly equivalent initial activity, which showed remarkable stability compared free ones. Encouragingly, had yield up 800 mg/L, allowing cost-effective CA-assisted absorption desorption solutions. results show that reduced time from 70 min 40 °C 25 96 25%MDEA+1%[N1111][Gly] final load stripped amount same time. exhibits maximum reaction rate °C; regeneration efficiency improved 60% 87 72%. When concentration 1.5 g/L, reached about 90% 25% MEA solution. These demonstrate simplicity preparation outstanding properties DvCA8.0-F, paves feasible way capture. This exciting may also have excellent potential enzymes innovative chemical synthesis achieve sustainable development green chemistry.
