Zinc oxide is one of the novel metal oxides utilized for diverse applications. The sol−gel and unintended selfpropagation procedures were applied to synthesize the porous and high surface area ZnO-based metal oxide nanocomposite. The p-type manganese(III) oxide was successfully coupled with n-type ZnO. The physical property characterization results revealed the surface area, porosity, and charge transfer capability improvement on the poly(vinyl alcohol) (PVA)-aided binary nanocomposite (PVA-ZnO/Mn 2 O 3 ), compared to ZnO. The XRD patterns and TEM image analysis validated the nanometer size range for the materials (15−60 nm). The SEM micrographs and BET spectral details have confirmed the porous nature of the PVA-ZnO/Mn 2 O 3 nanocomposite. The supporting results were obtained from the HRTEM (IFFT) and SAED pattern analyses. The EDX and HRTEM analyses were used for the confirmation of elemental composition and reality of the PVA-ZnO/Mn 2 O 3 composite, respectively. The presence of the improved charge transfer property for PVA-ZnO/Mn 2 O 3 , compared to ZnO, was evidenced from acid orange-8 dye degradation. The highest zone of inhibition (14 mm) was recorded on Escherichia coli bacteria for the uncalcined PVA-ZnO/Mn 2 O 3 nanocomposite compared to PVA, yet, less zone of inhibition compared to the calcined PVA-ZnO/Mn 2 O 3 nanocomposite. The authors recommend the formation of the couple between metal oxides by electrochemical technique analyses as a future work.

“…This may indicate the presence of only a local heterojunction between the ternary metal oxides [8,31,32]. The XRD data and the respective size of the particles were calculated using Debye-Scherrer's formula (D = Kλ/ (βcos(θ)), where λ is the wavelength of X-ray radiation (for Cu 0.15418 nm), K is constant close to unity, β is the full width at half maximum (FWHM) in 2θ scales and θ is the angle of the considered Bragg reflection [33,34].…”

Zinc oxide (ZnO) is a fascinating semiconductor material with many applications such as adsorption, photocatalysis, sensor, and antibacterial activities. By using a poly (vinyl alcohol) (PVA) polymer as a capping agent and metal oxides (iron and manganese) as a couple, the porous PVA-aided Zn/Fe/Mn ternary oxide nanocomposite material (PTMO-NCM) was synthesized. The thermal, optical, crystallinity, chemical bonding, porosity, morphological, charge transfer properties of the synthesized materials were confirmed by DTG/DSC, UV–Vis-DRS, XRD, FT-IR, BET, SEM-EDAX/TEM-HRTEM-SAED, and CV/EIS/amperometric analytical techniques, respectively. The PTMO-NCM showed an enhanced surface area and charge transfer capability, compared to ZnO. Using the XRD pattern and TEM image analysis, the crystalline size of the materials was confirmed to be in the nanometer range. The porosity and superior charge transfer capabilities of the PTMO-NCM were confirmed from the BET, HRTEM (IFFT)/SAED, and CV/EIS analysis. The adsorption kinetics (adsorption reaction/adsorption diffusion) and adsorption isotherm test confirmed the presence of a chemisorption type of adsorbate/methylene blue dye-adsorbent/PTMO-NCM interaction. The photocatalytic performance was tested on the Congo red and Acid Orange-8 dyes. The superior ascorbic acid sensing capability of the material was understood from CV and amperometric analysis. The noble antibacterial activities of the material were also confirmed on both gram-negative and gram-positive bacteria.

Graphene is currently emerging as an alternative to traditional conductive materials, such as copper and silver because of its excellent electrical conductivity and earth's carbon abundance. Graphene can be applied in many different electronic fields with different manufacturing methods to meet their specific requirements, which promote the development of advanced manufacturing technology in graphene electrical applications. Inkjet printing, as an environmentally friendly, low-cost and simple-to-operate advanced manufacturing method, has broad development prospects especially in the field of flexible electronics. In this review, several factors affecting the electrical conduction property of graphene applications in the inkjet-printed graphene process are listed as follows: the preparation method of ink, material and treatment of substrate, thickness of print, and annealing, especially whether a coffee ring is produced. In addition, this paper also cites some examples of inkjet-printed graphene in electrical conductivity. In order to continuously improve the procedure designs of graphene electronics fabrication, more accurate relationships between electrical conductivity of graphene and these parameters can be built. Based on the excellent prospect of inkjet printing technology in the field of conductive electronics, there will be some further research about the perfect implementation of graphene's electrical conductivity.
