“…Similar interactions were also noted by Rojas et al [75] . using benzimidazole‐based ionic liquid (IL) to modify the ZnO surface where the carboxylic group of IL binds efficiently with Zn and O atoms through electrostatic force, i. e., Zn atom exists in a distorted tetragonal geometry, acting as an electron sink to allow its interaction with IL.…”

Extensive use of zinc oxide and accelerators such as diphenyl guanidine (DPG) in the vulcanization of rubber composites entail potential environmental risks. These are pervasive contaminants of roadway runoff originating from tire wear particles (TWPs). Herein, the effect of phosphonium ionic liquids (PILs) in styrene-butadiene rubber compounds was demonstrated with reduced ZnO loading and no DPG to minimize the environmental footprint of the vulcanization process. The structure and chemistry of PILs were found to be the influencing parameters impelling the cross-linking kinetics, enabling shorter induction times. The generation of active Zn 2 + sites by PILs was examined through FTIR spectroscopy, calorimetry, and molecular dynamics simulations. From a tire application perspective, the PILs not only enhanced the cure kinetics but also improved the dynamic-mechanical behavior of the rubber composites. Consequently, the harm caused by TWPs to the atmosphere, fuel intake, and CO 2 emissions was minimal, thereby confirming the potential use of PILs in the tire industry.

“…As ZnO has interesting surface properties, which drive the many applications mentioned before, it is a great candidate to serve as a base to be linked with Hb [22]. Even though ZnO has been functionalized with many molecules in other studies that focused on CO 2 capture (such as benzimidazole-based ionic liquid [23], carbon nitride [24], and multiwalled carbon nanotubes and SiO 2 [25]), finding accessible methodologies for achieving a commercial device is a current need [26]. Furthermore, understanding the relationship between the morphology in an inorganic material and the functionalization efficiency with an organic molecule is a topic of great interest for many applications [27].…”

In this study, nanostructured ZnO arrays were synthesized by an accessible thermal oxidation (TO) methodology. The Zn films were chemically etched with nitric acid (HNO3) and then oxidized in a furnace at 500 °C for 5 h. Two different morphologies were achieved by modifying the HNO3 concentration in the etching process: (a) ZnO grass-like nanostructures and (b) rod-like nanostructures, with an etching process in HNO3 solution at 2 and 8 M concentration, respectively. The physical and chemical properties of the samples were analyzed by X-ray diffraction (XRD), scanning (SEM) and transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), and Raman spectroscopy. Both morphologies were functionalized with hemoglobin, and a difference was found in the efficiency of functionalization, which was monitored by UV–Vis spectroscopy. The sample with the highest efficiency was the ZnO grass-like nanostructures. Afterward, the capture of carbon dioxide was evaluated by monitoring a sodium carbonate solution interacting with the as-functionalized samples. The evaluation was analyzed by UV–Vis spectroscopy and the results showed a CO2 capture of 98.3% and 54% in 180 min for the ZnO grass-like and rod-like nanostructures, respectively.
