📄 Abstract（原文）
Global warming, driven by greenhouse gas emissions, has led to rising temperatures, more frequent natural disasters, environmental disruptions, and economic strain. CO₂ accounting for 76% of greenhouse gases, is the primary culprit. Reducing atmospheric CO₂ through carbon capture can mitigate this crisis. Ceramic materials, particularly zeolites, offer a promising alternative to traditional amine-based absorbents, as they require less energy for regeneration and are potentially more cost-effective. While ceramic materials have versatile applications, conventional manufacturing of complex shapes is costly, largely due to tooling expenses. Additive manufacturing (AM), particularly binder jetting, can reduce these costs by eliminating tooling. Binder jetting involves spreading powder layers and spraying binder to build a part, layer by layer, until complete. This process supports complex geometries, minimizes binder usage, and holds a strong potential for large-scale production. Binder jetting enables the creation of interconnected pore structures in ceramics, allowing efficient CO₂ adsorption. In this research, zeolite monolithic adsorbents were fabricated through a binder jetting AM process. A gyroid structure was successfully printed. A compressive strength of 1.06 MPa was achieved on green parts. Following printing, the parts were debound at 470°C and subsequently sintered at 750°C, achieving a strength of 0.45 MPa. The sintered samples demonstrated excellent CO₂ adsorption capacities although the adsorption performance did not fully match that of raw zeolite powder. These findings indicate the potential of binder jetting to produce structurally robust, porous zeolite adsorbents for carbon capture applications, with opportunities for further optimization to enhance adsorption performance.
