“…A further improvement of the mechanical strength was obtained by sintering the structures at temperatures between 900 • C and 1500 • C, reaching a compressive strength up to 11.09 MPa. In a more recent report, Som et al developed a 3D-printed architecture reporting on ZnO-based hierarchical structures for enhanced photocatalytic performance [107]. They formulated a ZnO ink based on 20-40 nm sized ZnO NPs.…”

Solution-based printing approaches permit digital designs to be converted into physical objects by depositing materials in a layer-by-layer additive fashion from microscale to nanoscale resolution. The extraordinary adaptability of this technology to different inks and substrates has received substantial interest in the recent literature. In such a context, this review specifically focuses on the realization of inks for the deposition of ZnO, a well-known wide bandgap semiconductor inorganic material showing an impressive number of applications in electronic, optoelectronic, and piezoelectric devices. Herein, we present an updated review of the latest advancements on the ink formulations and printing techniques for ZnO-based nanocrystalline inks, as well as of the major applications which have been demonstrated. The most relevant ink-processing conditions so far explored will be correlated with the resulting film morphologies, showing the possibility to tune the ZnO ink composition to achieve facile, versatile, and scalable fabrication of devices of different natures.

We report on the fabrication of porous ZnO microspheres (pZnO MSs) grafted with thermo-responsive polymers of poly(N-isopropylacrylamide) (PNIPAM) via surface-initiated atom transfer radical polymerization (SI-ATRP) for photocatalysis applications. Photodegradation of Rhodamine B (Rh-B) is used to evaluate the photocatalysis performance of pZnO MSs grafted with PNIPAM (pZnO MSs-PNIPAM). The results show that pZnO MSs-PNIPAM exhibits a reversible temperaturecontrolled photocatalysis activity and good recycling perform-ance. By adjusting the environmental temperature, the photocatalysis property of pZnO MSs-PNIPAM can be turned on/off, resulting in a temperature-controlled switching function of the obvious/unobvious photocatalysis performance below/upon the lower critical solution temperature (LCST) of PNIPAM. Additionally, the dispersion property of pZnO MSs-PNIPAM in water can also be regulated by changing the environment temperature, demonstrating the potential applications in that of photocatalysis-related fields for the graft systems.
