Carbon capture and storage (CCS) technologies are employed to mitigate global warming by removing carbon from the atmosphere. To enhance efficiency, nanoparticles have gained considerable attention as catalysts due their large surface area, tunable properties, regeneration, enhanced reactivity. However, it poses some challenges, such nanoparticle aggregation reduced effectiveness in sustainable solvents like seawater. address these limitations promote an environmentally method for capture, this study evaluates CO2 efficiency of seawater using nickel (NiNPs) coated with polyvinylpyrrolidone (PVP) a catalyst. We examined time-dependent size variations bubbles flow-focusing microchannel high-speed bubble-based microfluidics, directly associated transitory dissolution into surrounding solution. hypothesized that smaller polymer-coated NiNPs, higher surface-to-volume ratio, can solubility rates under identical environmental conditions. verify this, NiNPs three different sizes—5 nm, 10 20 nm—were synthesized tested. The experiments revealed 5 nm achieved rate 77%, contrast 71% 43% particles. These findings validate hypothesis, demonstrating facilitate more effective equivalent material quantities, thereby potentially improving overall reduction. This innovative approach contributes advancing NiNP-based saltwater-based capture.
