Rb10Mo36S38: A Novel Reduced Molybdenum Sulfide Containing the Highest Nuclearity Metal Transition Cluster in a Solid-State Compound
sixth member of the family of M2n-2Mo6nX6n+2 structures (M=Rb, Cs; X=S, Se, Te), which contains Mo6n clusters, is represented by Rb10Mo36S38. The Mo36 cluster present in the title compound results from the uniaxial trans face sharing of eleven Mo6 octahedra, and forms a Mo36S44 cluster unit with 44 sulfur atoms of its environment (38 inner, 6 outer ligands). The large cavities between these units are

Eight homoleptic metal(III) arylchalcogenolate polymers [M(EPh-p-X)3]n (M = Ru, Cr, and Mo) were characterized by PXRD. Structural solution of [Ru(SPh-p-tBu)3]n1 was achieved by Rietveld refinement of the PXRD data. Pyrolysis of [Ru(SePh)3]n4 produced nanostructured RuSe2, which selectively catalyzed the reduction of nitro compounds in the presence of other functionalities.
Abstract In order to improve the electrocatalytichydrogenevolutionreaction (HER), semiconductor heterojunctions must be further developed. In the present investigation, three-dimensional scaffold-like networks, consisting of gold (Au), bismuth sulfide (Bi2S3), and molybdenum disulfide (MoS2), have been developed and constructed. The main purpose was to improve the HER performances of a MoS2-based

production activity, and its hydrogenproduction rate is 293 μmol h−1 g−1, which is more than 3 times that of sample C. After 4 cycles of photocatalytic experiments, the photocatalytic activity is still stable, and the XRD diffraction peak does not appear obvious shift, which provides a new way for the design and preparation of efficient and stable photocatalyticmaterials.
在这项研究中,CDIN 2小号4 / MOS 2的复合结构是通过一个简单的两步水热合成法来制备,并且CDIN 2小号4 / MOS 2的复合结构的样品,其特征在于X射线衍射(XRD),扫描电子显微镜 (SEM)、X 射线光电子能谱 (XPS) 和紫外-可见漫反射光谱 (UV-vis)。由于MoS 2在CdIn 2 S 4颗粒表面的有效负载,CdIn 2 S 4 /MoS 2的光催化性能复合材料在可见光照射下(λ = 420 nm)显着改善,表明有效抑制了光生电子空穴的复合。同时,增加了CdIn 2 S 4的可见光响应,延长了光激发载体的寿命。摩尔含量为9%的CdIn 2 S 4 /MoS 2 (样品2CM)复合样品催化产氢活性最高,产氢率为293 μmol h -1 g -1,是样品C的3倍以上。经过4次光催化实验循环后,光催化活性依然稳定,XRD衍射峰未出现明显偏移,为设计制备高效、高效、稳定的光催化材料。
