Abstract

The authors first report the three-dimensional (3D) structured CeO2–PLA scaffold using a 3D printing methodology. The scaffold is prepared by decorating functional metal-oxide nanoparticles onto the 3D-printed polylactic acid (PLA) platform via an electrostatic interaction and is applied to the applications for photochemical degradation. As-designed CeO2–PLA scaffold shows high photocatalytic degradation performance toward methyl orange under a light irradation. Furthermore, the CeO2–PLA scaffold shows reasonable degradation performance even after it is washed and reevaluated; this result demonstrates the benefit of 3D-printed CeO2–PLA scaffold that it can be recycled several times without losing the catalysts.
