Special Issue Information

Dear Colleagues,

Our previous Special Issue, “10th Anniversary of Inorganics: Inorganic Materials”, published in 2023, received great attention, collecting 25 interesting papers (21 articles and 4 reviews) with the second highest number of published contributions to the journal Inorganics from a Special Issue. This Special Issue is the first in the Inorganic Materials section, and has attracted the attention of many potential authors and readers, with more than 59,000 views (data as of 5 March 2025). Meanwhile, the first edition of this Special Issue, entitled “Featured Papers in Inorganic Materials 2024”, published in 2025, collected 10 papers (9 articles and 1 review) and received more than 12,000 views (as of 5 March 2025). Due to the success of this Special Issue and the high level of interest in this topic, we have decided to launch the Special Issue "Featured Papers in Inorganic Materials 2025" as a complementary Special Issue, with the aim of continuing the discussion on recent advancements in the field of functional inorganic materials for a 'green' and sustainable future.

Therefore, it is with great pleasure that we may cordially invite colleagues and experts in the field of inorganic materials to submit original articles and critical reviews describing the synthesis of inorganic materials following alternative ecofriendly methods, new protocols and strategies for the reuse of inorganic materials, and newly emerging areas of interest involving the sustainable use of inorganic materials. The relationships between material structure and properties are of general interest, and may lead to discoveries of novel functional materials, which may lead to the development of new technologies. This Special Issue will embrace studies on a wide range of materials with fascinating structures and properties, for a wide range of applications.

We look forward to receiving your valued contributions.

The hydrogen sorption and electrochemical properties of the alloy Mg50Ni12.5Al12.5V12.5Fe12.5 synthesized by ball milling under the protected atmosphere of argon for 50 h in a planetary ball mill are investigated. The significantly fast rate of absorption reaction is observed along with the hydrogen absorption capacity of 2.04 wt.% H2 at temperatures 200 and 300 °C and at a pressure of 1 MPa. Even at room temperature, the absorption capacity is relatively high, and it is about 1.6 wt.% H2. The alloy ball milled for 50 h and the alloy after cycling and hydrogenation were characterized by X-ray diffraction analyses, SEM, and TEM. The prepared alloy was tested as an anode in a Ni/MH battery in a 6 M KOH electrolyte. Galvanostatic and potentiostatic discharge modes were employed, revealing activation after the third cycle and giving a discharge capacity of 257 mAh/g. Full article

Applying the melt quenching method (cooling rate 101–102 K/s), new multicomponent vanadate glasses were synthesized, containing different amounts of MoO3 at the expense of B2O3 with the composition 20Li2O:(30 − x)B2O3:50V2O5:xMoO3, x = 10, 20 mol%. The obtained samples were characterized by X-ray diffraction, infrared spectroscopy, differential scanning calorimetry and impedance spectroscopy. The density of the glasses was measured by the Archimedes method, on the basis of which the physicochemical parameters molar volume, oxygen molar volume and oxygen packing density were calculated. It was found that the replacement of B2O3 with MoO3 leads to changes in electrical conductivity, which are a consequence of the increase in non-bridging oxygen atoms in the amorphous structure. The electrochemical characterization of the 20Li2O:(30 − x)B2O3:50V2O5:20MoO3 glass obtained was performed by assembling an all-solid-state cell, employing 20Li2O:(30 − x)B2O3:50V2O5:20MoO3 glass as a cathode active material. The obtained results show that the studied glass compositions are interesting in view of their potential application as cathode materials in all-solid-state lithium-ion batteries. Full article

Photocatalytic H2 production is one of the most promising approaches for sustainable energy. The literature presents a plethora of carefully designed systems aimed at harnessing solar energy and converting it into chemical energy. However, the main drawback of the reported photocatalysts is their stability. Thus, the development of a cost-effective and stable photocatalyst, suitable for real-world applications remains a challenge. An ideal photocatalyst for H2 production must possess appropriate band-edge energy positions, an effective sacrificial agent, and a suitable cocatalyst. Among the various photocatalysts studied, TiO2 stands out due to its stability, abundance, and non-toxicity. However, its efficiency in the visible spectrum is limited by its wide bandgap. Metal doping is an effective strategy to enhance electron–hole separation and improve light absorption efficiency, thereby boosting H2 synthesis. Common metal cocatalysts used as TiO2 dopants include platinum (Pt), gold (Au), copper (Cu), nickel (Ni), cobalt (Co), ruthenium (Ru), iron (Fe), and silver (Ag), as well as bimetallic combinations such as Ni-Fe, Ni-Cu, Nb-Ta, and Ni-Pt. In all cases, doped TiO2 exhibits higher H2 production performance compared to undoped TiO2, as metals provide additional reaction sites and enhance charge separation. The use of bimetallic dopants further optimizes the hydrogen evolution reaction. Additionally, porphyrins, with their strong visible light absorption and efficient electron transfer properties, have demonstrated potential in TiO2 photocatalysis. Their incorporation expands the photocatalyst’s light absorption range into the visible spectrum, enhancing H2 production efficiency. This review paper explores the principles and advancements in metal- and porphyrin-doped TiO2 photocatalysts, highlighting their potential for sustainable hydrogen production. Full article
