Catalysts are widely used in the chemical industry because of their environmental friendliness and low energy consumption.However,integrated fabrication of catalytic reactors(CRs)remains challenging.In this study,we propose the integrated manufacturing of a palladium-carbon(Pd/C)CR for the first time.The outer shell ink com-prises Al2O3 powder and aluminum dihydrogen phosphate(AP),whereas the inner core ink consists of activated carbon powder,AP,and polymethylmethacrylate(PMMA).By integrating with the coaxial 3D printing strategy,the Pd/C CR can be freeform-designed with different core thicknesses,lengths,and shapes(W-type,L-type,and U-type).Based on this,a CR with excellent catalytic properties was further developed by loading palladium(Pd)particles.Typically,the resultant Pd/C CR with a length of 2.5 cm exhibits a catalytic efficiency of up to 97.6％after 60 min.This method of preparing Pd/C CR using coaxial 3D printing combines multimaterial 3D print-ing,integrated molding,and complex biomimetic structure fabrication.This offers a feasible and cost-effective solution that uses a simple fabrication process.
