Despite the need to liquefy CO2 and to add temporary storage facilities for loading and unloading onto ships, beyond a certain distance at fixed CO2 transported and plant life, ship transport optimal at pressures of 7 or 15 bar depending on the type of vessel.

The number density results reveal that MXene stratifies the ILs between the layers, with higher concentrations of ILs near MXene and lower concentrations in the middle layer. Notably, MXene has a greater impact on cations distribution compared to anions. As the layer spacing of MXene expands from 1.5 to 3 nm, the interaction between MXene and IL weakens, while that between the cations and anions strengthens. The confined ILs enhance gas solubility capability but impede gas diffusion. CO2 is distributed closer to anions, while CH4 tends to be closer to cations, with the distance between CH4 and cations decreasing as the layer spacing increases. Additionally, with the increase of layer distance, the proportion of confined ILs gradually decreases, and the gas diffusion coefficient gradually increases.

By integrating waste plastic into new products and materials, upcycling supports a more sustainable and environmentally friendly economic model. This reduces the overall environmental footprint, including CO2 emissions, associated with plastic consumption. Moreover, converting plastic waste into carbon nanotubes, can effectively sequester carbon. This means that carbon is captured and stored in a stable form, preventing its release into the atmosphere as CO2. This contributes directly to reducing net emissions. Recent interest in upcycling strategies includes producing target-oriented catalysts to reform plastic waste into carbon nanotubes embedded spent catalysts, offering potential for various applications. However, research in this area is scattered and lacks comprehensive conclusions. This review critically examines the use of spent catalysts from plastic waste pyrolysis and identifies their suitability for practical applications. It suggests focusing on the catalytic pyrolysis of plastic waste for target-oriented catalysts, as they offer good hydrogen yield and post-pyrolysis use in targeted applications. The unique structure of these catalysts enhances performance compared to commercial alternatives, but post-treatment is crucial to remove impurities for optimal performance.
