Topic Information

Dear Colleagues,

We are pleased to invite you, along with the members of your research group, to contribute to the forthcoming MDPI Topic, entitled “Synthesis, Characterization and Performance of Materials for a Sustainable Future, 2nd Volume”. This Topic is a continuation of the previous successful work on the "Synthesis, Characterization and Performance of Materials for a Sustainable Future". Today, sustainability represents the key factor for economic progress which is in compliance with social advancement and environmental protection, driving innovation in materials, processes and technologies. Therefore, proceeding from the need for innovative chemical formulations for advanced (nano)materials, inorganic/organic/coordination compounds, porous composites, hybrid/multifunctional or nanostructured supported systems, this Topic aims to present recent advances in, challenges of and opportunities for the application of functional materials in different fields, including catalysis, photocatalysis, electronics, optics, energy and environment, according to green chemistry and green engineering concepts and eco-efficiency, industrial ecology and sustainable processes from an environment and economic point of view. In this respect, a more rational use of natural sources and solid wastes must be addressed, as well as the application of novel synthetic procedures for energy saving. Specific attention should also to be paid to the potential of modeling as an analytical tool for matching the peculiar structure–reactivity relationships of materials, highlighting mechanistic clues to controlling their behavior in processes of industrial interest. Relevant subject areas to be covered in this Topic span from material-to-application including:

  • Production of green hydrogen;
  • Purification of gaseous streams from industrial processes;
  • Power-to-gas approaches;
  • CCUS strategies to reach net zero or negative GHG emissions;
  • Synthesis of sustainable chemicals and fuels;
  • Conversion of biomass and wastes to added value products;
  • Treatment of air, water and soil pollution.

Review articles surveying recent research trends, original research articles, high-quality research notes or short communications are to be preferentially delivered to the following journals: Catalysts, Materials, Nanomaterials, Polymers and Sustainability. We hope that you will be able to accept this invitation and contribute to the ongoing success of this outstanding Topic.

Cobalt, nickel, manganese and zinc vanadates were synthesized by a hydrometallurgical two-phase method. The extraction of vanadium (V) ions from alkaline solution using Aliquat® 336 was followed by the production of metal vanadates through precipitation stripping. Precipitation stripping was carried out using solutions of the corresponding metal ions (Ni (II), Co (II), Mn (II) and Zn (II), 0.05 mol/L in 4 mol/L NaCl), and the addition time of the strip solution was varied (0, 1 and 2 h). The time-dependent experiments showed a notable influence on the composition, structure, morphology and crystallinity of the two-dimensional vanadate products. Inspired by these findings, we selected two metallic vanadate products and studied their properties as alternative cathode materials for nonaqueous sodium and lithium metal batteries. Full article

Electrolytic water splitting is a promising path for the production of clean hydrogen when combined with green electric power, such as photovoltaic and wind power; however, the high current water electrolysis is mainly dependent on the utilization of Pt, Ru, and other expensive materials, while the transition metal-based catalysts still need improvement in electrocatalytic activity and stability. Here, we present the preparation of economic and scalable electrode materials, Nickel-Iron phosphide/Nickel foam (NiFeP/NF), with a hierarchical porous structure for overall water splitting as both the anode and cathode. An overall potential of 1.85 V for the current density of 100 mA cm−2, and a long lifetime of 700 h, were achieved by using NiFeP/NF as both the anode and cathode. The nanostructures of the composite phosphides were investigated and the spent electrode after long-term electrolysis was characterized to investigate the long-term failure mechanism of the phosphides. Surface shedding and reconstruction theories were proposed for the failure of the NiFeP/NF cathode and anode in long-term electrolysis, respectively. Furthermore, TiO2 coating was proved to be an efficient strategy to elongate the lifetime of the phosphide electrodes, which shows a slow current decline rate of 0.49 mA·cm−2 h−1. Full article

At present, the conservation of the environment represents an objective that everyone wants to achieve. The construction industry has influenced the advancement of alternative materials that comply with sustainable development. In this article, reinforced concrete was obtained by mixing 80% blast furnace slag and 20% fly ash. These concentrations were chosen because they provide the lowest porosity in the cementitious matrix. Rice husk ash was used as an activator. Guadua angustifolia fibers were used to evaluate the mechanical performance of the concrete. The composition of the raw material was determined by X-ray fluorescence, the microstructure of the fibers by AFM, and the SEM technique was used to determine the surface characteristics of guadua fibers and concrete mixes. The structural characterization using XRD, the structure of the molecules of the guadua fiber, and the composition of the mixture’s molecular mixtures were determined by FTIR spectroscopy. Its properties, such as tensile strength and flexural strength, were analyzed. The results indicated that the concrete with the addition of Guadua angustifolia fibers. The results indicated that the concrete with the addition of guadua angustifolia fibers showed the best mechanical behavior. Tensile strength was optimized, establishing values of 2.68 MPa for unreinforced concrete and up to 3.12 MPa for fiber-reinforced concrete. The flexural strength values increase at ages after 28 days due to the pozzolanic reaction generated. Values of 2.8 MPa were obtained for concrete without fiber and 3.5 MPa for concrete reinforced with guadua angustifolia fiber. Full article
