Ternary nickel phosphide (Ni2P) and titanium carbide (Ti2C2) MXene supported titanium dioxide nanoparticles (TiO2 NPs) to construct a Ni2P/TiO2 NPs/Ti3C2 MXene hybrid composite for stimulating photocatalytic hydrogen production has been investigated. The performance comparison of two-dimensional (2D) Ti3C2 MXene multilayers with in situ grown TiO2 NPs synthesized through etching and atmospheric calcination methods was conducted and promising separation of charge carriers was observed. TiO2 NPs embedded over 2D Ti3C2, synthesized through both methods, were found to have promise in promoting photoactivity, whereas 2.89 times more H2 yield was attained with TiO2 NPs embedded through the oxidation (ox) approach. Using the Ni2P/TiO2/Ti3C2-ox heterostructure, a rate of 9425 ppm g–1 h–1 of H2 was reached, 2.77, 4.81, and 8.28 times more than those using Ni2P/TiO2, TiO2/Ti3C2 and TiO2 samples, respectively. This obviously augmented H2 production rate can be ascribed to a binary cocatalyst with efficient charge carrier separation, higher light absorption, and more attachment of water molecules. Among different alcohols, glycerol was a promising reagent to yield more hydrogen in addition to having higher photostability in consecutive cycles. This study provides a new approach to construct a ternary nanocomposite with proficient charge carrier separation and would be beneficial for other energy applications.

Ceramics is one of the oldest materials prepared and used by human beings. Ancient ancestors started to make pottery by forming and burning clay since the earliest civilizations. Ancient people started to fabricate burnt claywares since %6500 B.C., and clayware as a commercial product was available by %4000 B.C. [1] In modern society, as one of the largest branches in material family, ceramics have been developed and used in almost every fields of human beings' lives. In some senses, ceramics and metals possess complementary properties; generally, ceramics show the advantages of high strength, high hardness, high chemical stability, high wear resistance, whereas ceramics typically show intrinsic brittleness and poor plasticity due to their covalent and/or ionic chemical bonding; metals have good plasticity, high toughness, and high thermal and electronic conductivity; however, they typically show lower chemical stability and lower hardness than ceramics. It would be marvelous for a material to combine the properties of ceramics and metals. MAX phases are the materials that meet the challenge.MAX phases are a family of nanolaminate ternary nitrides and carbides, which were first discovered by Nowotny and his colleagues in Vienna. [2] In the beginning, MAX phases have a general formula of M nþ1 AX n (n ¼ 1-3), where M is a transition metal, A is an element from group A, and X is either carbon or nitrogen. The n value could be 1, 2, or 3, and the phases are named as 211, 312, and 413 MAX phases, respectively. These MAX phases show a hexagonal crystal structure (P63/mmc), consisting of M 6 X octahedra separated by A atomic layers. [3] M─X bonds in M 6 X octahedra are strong covalent bonds, whereas the M─A bonds between M 6 X and A atomic layer are much weaker, especially in shear. This unique bonding structure is analogous to graphite, and it is the special bonding structure that endows MAX phases properties of both ceramics and metals. On the one hand, MAX phases are stiff, lightweight, chemically stable, and oxidation resistant, which are the features of ceramics; on the other hand, they exhibit good electric and thermal conductivity as well as excellent machinability and damage tolerance, which are the features of metals.Unfortunately, MAX phases had not attracted enough attention in both academia and industry until 1996 when Barsoum et al. [4] synthesized and characterized Ti 3 SiC 2 . Ever since then, material researchers become more interested in this material. [5] In the past two decades, many MAX phases have been synthesized and tested to show highly unusual properties, [6] which will be discussed with detail in the following sections. The intensive extent of the researches on MAX phases can be demonstrated by the published papers (Figure 1). A remarkable jump can be observed between 1998 and 1999, and after that, the number of published papers increases steadily, reaching as high as 980 papers in 2019 (Figure 1a). From another aspect, the citation of the milestone paper published by Barsoum [4] also signific...

“…Plus, it is feasible to deposit heterogeneous multilayer coatings with excellent adhesion to the substrate, providing a dense film possessing a high deposition rate. [28][29][30] Although so far TiN has been intensively studied as a coating material, the other binary nitrides and carbides of the transition metals have also attracted considerable interest. Among the developed new materials, ternary nitrides and carbides mostly titanium-based are being increasingly studied and to some extent technically used.…”

The examination of the existing relationships between nanoindentation responses and tribological properties of the nanostructured CrN, Cr(CN), and (CrTi)N coatings was the matters to be considered in this research. A cathodic arc physical vapor deposition machine was therefore implemented to apply the chosen coatings on the DIN 1.2510 tool steel substrate. Moreover, an X‐ray diffraction and a field emission scanning electron microscope were utilized in order to show the features regarding microstructure and morphology of these very coatings. The mechanical and tribological behavior of the coatings was expected to be assessed with the use of a nanoindentation and pin‐on‐disc wear tests. According to the obtained result, the wear resistance and hardness value of the (CrTi)N coating were proved to be much better than those of the CrN and Cr(CN). Linear equations were proposed between wear rate/hardness and friction coefficient/hardness to evaluate the correlation between mechanical and tribological properties. The presence of a quadratic equation between the friction coefficient and the plastic deformation index was also discovered.
