Decomposition of 2-Propanol over Molybdenum …

The decomposition reactions of 2-propanol over molybdenum disulfide (MoS 2) catalysts were studied at 250°C by use of apulse reactor, using 20mg catalyst under the carrier gas (He) flow of 30ml/min. In the decomposition of 2-propanol over MoS 2, dehydration proceeded preferentialy to form a large amount of propylene and a trace amount of diisopropylether, while dehydrogenation proceeded ...

Recent progress in atomic layer deposition of …

As a kind of specially modified chemical vapor deposition (CVD), atomic layer deposition (ALD) has long been used to fabricate thin films. The self-limiting reaction of ALD endows the films with excellent uniformity and precise controllability. The thickness of the films obtained by ALD can be controlled in an atomic scale (0.1 nm) on a large-area substrate even with complex structures.

Layered molybdenum disulfide coated carbon hollow …

Through supramolecular assembly method, molybdenum disulfide (MoS 2) is uniformly anchored on the mesoporous hollow carbon spheres (HCS), which are obtained by hard template method.The introduction of HCS can prevent the agglomeration of MoS 2 and decrease the electric resistance of the compound material MoS 2 @HCS. The composite of MoS 2 @HCS‐17 also owns a specific surface area of 119.0 …

Microscopic Insights into pH-dependent Adsorption …

The EXAFS spectra revealed the coexistence of two sorption types. The inner-sphere complexation was formed in the form of Cd-S bond at lower pH (3.56, 6.48), while the Cd(OH) 2 precipitation occurred in the form of Cd-O and Cd-Cd bonds at higher pH (9.57).

Preparation of high-performance natural …

Molybdenum disulfide (MoS2) is a potential additive for rubber enhancement. However, its poor dispersion and weak interaction with matrix limit its further application. To improve the dispersion of MoS2 in natural rubber (NR) and enhance the interaction of MoS2 with matrix, single-layered MoS2 nanosheets are prepared and further modified by cysteine.

Poly(acrylonitrile)–molybdenum disulfide polymer ...

Elemental analysis, FT-IR spectra, thermal analysis and 7 Li MAS-NMR spectra indicate that the polymer is co-intercalated with lithium in the MoS 2 matrix. Lithium can be de-intercalated and intercalated electrochemically from the nanocomposite in the range x = 0.1–0.8.
