A ZnO@ABS/TPU/CaSiO₃ 3D skeleton and its adsorption/photocatalysis properties for dye contaminant removal

Abstract

Enhanced synergistic effect of photocatalytic and adsorption was realized through the system constructed of ZnO nanoparticle loaded 3D skeleton.

Application of 3D printing technology for green synthesis of Fe2O3 using ABS/TPU/chlorella skeletons for methyl orange removal

“…Importantly, samples of ATCh40, AT-a-FeOOH, and AT skeletons also exhibit a wide diffraction peak at 20.6°, indicating that these samples possess an amorphous nature. 6 The similarity in diffraction peaks between AT and ATa-FeOOH skeletons suggest a relatively low loading of a-FeOOH on the AT skeletons. Intriguingly, aer the introduction of chlorella, the diffraction peak of ATCh40 skeleton weakened at 20.6°, suggesting that chlorella may exert a shielding effect on the polymer.…”

“…4,5 Among these methods, photocatalysis stands out as one of the most convenient options, primarily due to its simplicity and relatively low cost, as it does not necessitate complex post-treatment procedures. Currently, widely utilized photocatalysts include ZnO, 6 TiO 2 , 7 Bi 2 O 3 , 8 WO 3 (ref. 9) and g-C 3 N 4 .…”

“…Due to its capability for designing complex structures, facilitating batch manufacturing, and its ease of operation, 3D printing has found utility across various fields, including drug release, 14 wastewater treatment, 15 gas capture, 16 catalyst development. 17 In addressing the fixation of photocatalyst, Zhang et al 6 employed a hydrothermal technique to immobilize nano-ZnO onto a CaSiO 3 /ABS/TPU 3D skeleton for removing RhB, achieving a remarkable 90% removal ratio over six consecutive runs. Kennedy et al 18 combined polylactic acid (PLA) with TiO 2 photocatalysts to produce a lattice using 3D printing, demonstrating an excellent photocatalytic efficacy.…”

Biogenic Synthesis of Cu‐Doped ZnO Photocatalyst for the Removal of Organic Dye

“…As a result of its wide bandgap energy, narrow visible light absorption, and high recombination rate of photo-generated electron-hole pairs, ZnO only is not applicable [ 24 ]. To overcome the limitations of ZnO, different researchers have concentrated on the development of heterojunctions of ZnO with other narrow bandgap semiconductors [ 25 , 26 ].…”
