“…These mechanisms must mission durations continue to push the demands placed on these lubricants requiring ultrahigh wear lives on the order of decades instead of months. [13,14] To address these limitations, MoS 2 has been co-deposited with an enormous range of additives including soft metals, [15][16][17][18][19] hard metals, [20][21][22][23][24] ceramics, [25][26][27][28][29][30] and combinations of all three to form "chameleon" coatings. [31][32][33][34] Most commonly, these additives are selected based on their chemical compatibility with MoS 2 including substitution into the lattice structure, dangling edge bond passivation, and preferential oxygen bonding, as well as their mechanical performance in increasing the wear resistance of the coating.…”

Molybdenum disulfide coatings have been employed as lubricants for spacecraft since the 1950s but continue to face major engineering challenges including performance in both terrestrial air and deep space vacuum environments and service lifetimes on the order of decades without maintenance. Co‐deposition of MoS2 with additive compounds provide enhancements in some circumstances but a lubricant which can perform in all space‐facing environments with long lifetimes remains an ongoing problem. Herein, it is demonstrated the multi‐environment adaptable performance of a novel MoS2 + tantalum lubricant coating, which excels as a lubricant in both terrestrial and space environments while the benchmark space‐qualified commercial MoS2 lubricants do not. It is noted that the 10% tantalum additive exhibits preferential oxidation in air to preserve the lubricating ability of MoS2 while forming phases of TaS2, which aid in the exceptional lubrication of MoS2 in ultra‐high vacuum. Additionally, completely different tribofilms of small particles and compact sheets are noted for air and vacuum environments, respectively, which allows for adaptable lubricating mechanisms from a single coating depending on the environment. This novel coating sets the benchmark as the first demonstrated instance of a fully versatile space lubricant which offers high‐performance in both terrestrial and deep space environments.

“…As well as Ag and Au, other common noble metals, such as Pt and Pd, have also been used to decorate MoS 2 . Luo et al [179] adopted an electrodeposition method to import Pt on MoS 2 and it exhibited a comparable HER activity. As reported by Yuwen et al [175] , they utilized a microwave-assisted method to disperse Pd on MoS 2 , leading to an enhanced catalytic activity for methanol oxidation.…”

Molybdenite (MoS2) has been widely used in the fields of catalysis, desalination, energy storage and conversion and optoelectronics as a result of its unique crystal structures and unusual properties. In the last decade, the modification of the surface, structural and semiconducting properties of zero-, two- and three-dimensional (0D, 2D and 3D) MoS2 for enhanced applications has attracted considerable attention. In this review, we summarize the synthesis, modification methods and application of 0D, 2D and 3D MoS2. The unique structures and properties of 0D, 2D and 3D MoS2 are first introduced. Next, the preparation methods of 0D, 2D and 3D MoS2 are summarized. The modification methods, including surface, structural and composite engineering, for enhancing the physical and chemical properties of 0D, 2D and 3D are also discussed. Finally, inspired by natural and modified MoS2, future suggestions for the design of novel 0D, 2D and 3D MoS2 for various applications are also suggested. This review offers new insights into the design and construction of novel and efficient 0D, 2D and 3D MoS2 for practical applications.
