Special Issue Information

Dear Colleagues,

The development of novel energy materials has been boosting the revolution of the energy structure in recent decades. One typical example is the battery technique. Since the discovery of secondary batteries, electrical devices have become increasingly popular, and the portion of green electricity in our society has increased dramatically. Nowadays, together with battery technology, other renewable energy technologies such as fuel cells, supercapacitors, solar cells, and electro(photo)catalytical hydrogen generation, play an increasingly important role in modern society. However, it is still a challenge to widely integrate these novel energy technologies into modern society due to a lack of appropriate materials to meet the demand of low-cost and satisfying performance. Research on low-cost and high-performance materials requires continuous effort. In this Special Issue, we would like to solicit manuscripts reporting recent progress in this area. The design, synthesis, processing, and characterization of low-cost materials and thin film devices, including but not limited to nano-oxides, nano-carbides and their composites, for renewable energy applications are highly encouraged.

The topics of interest include, but are not limited to, the following:

  • Novel approaches of material design, synthesis and processing for energy applications;
  • Synthesis of novel energy materials;
  • Understanding of structures and properties of novel materials;
  • Thin film energy devices;
  • Nanomaterials and nanostructures for energy applications;
  • Low-cost materials and manufacturing approaches.

This study tackles the critical demand for sustainable synthesis methods of reduced graphene oxide (rGO), highlighting the environmental drawbacks of conventional chemical processes. We introduce a novel, green synthesis technique involving the irradiation of a 500 eV argon ion beam, which not only facilitates the creation of micro-patterned rGO on a graphene oxide (GO) film but also enables simultaneous material characterization and patterning. By adjusting the irradiation exposure time between 0 and 80 s, we achieve meticulous control over the attributes and the reduction process of the material. The use of X-ray photoelectron spectroscopy (XPS) allows for real-time monitoring of the reduction from GO to rGO, evidenced by a notable reduction in the intensities of C-O, C=O, and O-C=O bonds, and an increase in C-C bond intensities, indicating a significant reduction level. Our research demonstrates the efficient production of eco-friendly rGO using precise, controlled argon ion beam irradiation, proving its advantages over traditional methods. These results contribute to the development of sustainable material science technologies, with potential applications in electronics, energy storage, and more. Full article

The present research work describes the synthesis and characterization of CuO/SiO2 for coating-perforated 304 stainless steel (SS) substrates to degrade methylene blue and amoxicillin under visible light irradiation. The foregoing photocatalytic system was achieved through the coprecipitation method by adding pure CuO to a SiO2 sol at 1:5, 1:10, and 1:15 molar ratios. The conditions for carrying out the depositions on the SS substrates (three per substrate) involved an immersion rate of 90 mm/min with a drying time of 20 min at 120 °C. The XRD technique confirmed the presence of the SiO2 amorphous phases and CuO monoclinic systems in the coatings, with a particle size distribution ranging from 0.5 to 2.5 μm (with an average of 1.26 ± 0.06 μm). As for SEM, it revealed a homogeneous coating surface without cracks. The produced photoactive CuO/SiO2 coatings were capable of degrading methylene blue (98%) at 1500 min and amoxicillin (55%) at 450 min. Full article

The reliable detection of environmental contaminants can correctly forecast the degree of environmental pollution that has occurred, which contributes to improving the environmental purification rate and maintaining the ecological balance. Herein, a novel hierarchical biomimetic catalysis MnO2@CuAl-CLDHs was designed and synthesized using a facile method, which exhibited significantly enhanced peroxidase-like activity due to the unique composition and hierarchical mesoporous structure. Under optimized operational conditions, a visible colorimetric array based on the superior nanozyme activity of MnO2@CuAl-CLDHs was developed for the quantitative determination of hydroquinone with a wide linear detection range (1–100 μM) and a low detection limit (0.183 μM). Simultaneously, our presented strategy could analyze hydroquinone in real water samples with high accuracy. Therefore, the bimetallic co-catalyzed nanozymes are expected to be the perfect replacement for natural enzymes to develop convenient and efficient sensors. Full article

The nanosheet-seeding growth (NSG) technique is an interesting synthesis method for preparing two-dimensional (2D) materials by employing ultrathin nanosheets as templates. In this work, the synthesis of 2D TiO2 nanoplates using Ti0.87O2 nanosheets via the NSG process is thoroughly studied to achieve a better understanding of this process. The influence of various synthesis conditions on the morphology and phase composition has been carefully examined. The study of synthesis time reveals that the TiO2 grows in the Stranski–Krastanov mode on the templates and the growth follows second-order kinetics. It is also found that the concentration of precursors and the synthesis time are the effective parameters in controlling the thickness of TiO2 nanoplates. The phase of the sample changes from anatase TiO2 to NH4TiOF3 and the morphology changes from flake to disk with the increase in the precursor concentration. The synthesis temperature has a large influence on the morphology and thickness of the sample but has little effect on the phase composition. However, the synthesis temperature changes the color of the sample, and a high temperature enlarges the light absorption range of the sample. Full article
