Special Issue Information

Dear Colleagues,

Nanoparticles, with dimensions ranging from 1 to 100 nanometers, exhibit unique properties due to their high surface-to-volume ratio. Advanced chemical engineering in nanoparticles holds great promise in revolutionizing various scientific and industrial sectors. This emerging field encompasses the synthesis process, materials characterization, physical/chemical properties, and various applications of nanoparticles. Understanding the fundamental principles behind nanoparticle chemistry and engineering is crucial for developing novel materials and devices with tailored functionalities.

Specifically, the synthesis process of nanoparticles involves the precise control over size, shape, and composition, which can be achieved through various chemical engineering techniques. The materials characterization plays a vital role in understanding the structure and properties of nanoparticles. Techniques such as X-ray diffraction, electron microscopy, and spectroscopy are commonly employed to analyze their chemical composition, crystal structure, and morphology. These characterizations help in tailoring the properties of nanoparticles for specific applications.

The physical/chemical properties of nanoparticles make them suitable for a wide range of applications. For example, Metallic nanorods find applications in catalysis, sensing and biomedical fields, while carbon nanotubes and graphene are utilized in electronics, energy storage, and composite materials. Recent cutting-edge topics in this field include the development of different kinds of nanoparticles, such as Au nanoparticles, up-conversion nanoparticles, metal-organic frameworks, for tumor-targeting drug delivery and environmental remediation.

In this study, we report the fabrication and characterization of silver nanoparticle-doped zinc oxide tetrapod substrates used for surface-enhanced Raman scattering to detect rhodamine B. Prior to this, silver nanoparticle-doped zinc oxide tetrapods were synthesized using the solar physical vapor deposition method. Subsequently, silver-doped zinc oxide tetrapods were applied onto silicon wafers via the droplet evaporation process. The surface-enhanced Raman scattering activity of the silver nanoparticle-doped zinc oxide tetrapod substrate was evaluated by detecting rhodamine B using Raman spectroscopy. Our results demonstrate that the silver nanoparticle-doped zinc oxide tetrapod substrate exhibits surface-enhanced Raman scattering activity and can detect rhodamine B at concentrations as low as 3 μg/mL. This study suggests that silver nanoparticle-doped zinc oxide tetrapod substrates have potential as surface-enhanced Raman scattering platforms as well as potential for the detection of biomolecules.

The design of economical and robust catalysts is a substantial challenge for the dry reforming of methane (DRM). Monometallic nickel-based catalysts used for DRM reactions had comparable activity to noble metals. However, they turned out to be less stable during the reactions. As a continuation of the interest in synthesizing catalysts for DRM, this paper evaluates the catalytic performance of bimetallic Co–Ni catalysts regarding their synergy effect, with graphene oxide (GO) as support for the first time. The synthesized bimetallic catalysts prepared via the wet-impregnation method were characterized using N2 physisorption analysis, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and X-ray diffraction (XRD). The catalytic test was performed in a stainless-steel tubular reactor in atmospheric conditions with a reaction temperature of 800 °C, time-on-stream (TOS) of 300 min and CH4: CO2 being fed with a ratio of 1:1. The bimetallic 10 wt%Co–10 wt%Ni/GO and 20 wt%Co–10 wt%Ni/GO catalysts had a similar BET specific surface area in N2 physisorption analysis. The XRD pattern displayed a homogeneous distribution of the Co and Ni on the GO support, which was further validated through SEM–EDX. The conversion of CO2, CH4, and H2 yield decreased with reaction time due to the massive occurrence of side reactions. High conversions for CO2 and CH4 were 94.26% and 95.24%, respectively, attained by the bimetallic 20 wt%Co–10 wt%Ni/GO catalyst after 300 min TOS, meaning it displayed the best performance in terms of activity among all the tested catalysts.
