Interaction of CO with catalyst surfaces prepared in situ in the electron spectrometer: evidence for CO2− and related species relevant to methanol synthesis

Interaction of CO with the Cu ZnO catalyst surfaces prepared in situ in the sample preparation chamber of the electron spectrometer has been investigated by X-ray photoelectron spectroscopy. The catalyst surfaces contained different proportions of Cu1+ and Cu0 species. Besides chemisorbed CO, CO2 − and CO3 2− species are found on the catalyst surface, the proportion of CO2 − and CO3 2− species relative to CO increasing with the Cu 1+ Cu 0 ratio. This observation is of significance to methanol synthesis.

Boron nitride nanotubes and nanowires

Simple methods of preparing boron nitride nanotubes and nanowires have been investigated. The methods involve heating boric acid with activated carbon, multi-walled carbon nanotubes, catalytic iron particles or a mixture of activated carbon and iron particles, in the presence of NH3. While with activated carbon, boron nitride nanowires constitute the primary product, high yields of clean boron nitride nanotubes are obtained with multi-walled carbon nanotubes. Aligned boron nitride nanotubes are produced when aligned multi-walled carbon nanotubes are employed as the starting material suggesting the templating role of the nanotubes. Boron nitride nanotubes with different structures have been obtained by reacting boric acid with NH3 in the presence of a mixture of activated carbon and Fe particles.

Structural Rationalisation of Co‐crystals Formed between Trithiocyanuric Acid and Molecules Containing Hydrogen Bonding Functionality

Crystallisation of trithiocyanuric acid (TTCA) from various organic solvents that have hydrogen bonding capability (acetone, 2-butanone, dimethylformamide, dimethyl sulfoxide, methanol and acetonitrile) leads to the formation of co-crystals in which the solvent molecules are incorporated together with TTCA in the crystal structure. Structure determination by single-crystal X-ray diffraction reveals that these co-crystals can be classified into different groups depending upon the topological arrangement of the TTCA molecules in the crystal structure. Thus, three different types of single-tape arrangements of TTCA molecules and one type of double-tape arrangement of TTCA molecules are identified. In all co-crystals, hydrogen-bonding interactions are formed through the involvement of N-H bonds of TTCA molecules in these tapes and the other molecule in the co-crystal. Detailed rationalisation of the structural properties of these co-crystals is presented.

A single molecule switch based on two Pd nanocrystals linked by a conjugated dithiol

Tunneling spectroscopy measurements have been carried out on a single molecule device formed by two Pd nanocrystals (dia, $\sim$5 nm) electronically coupled by a conducting molecule, dimercaptodiphenylacetylene. The I-V data, obtained by positioning the tip over a nanocrystal electrode, exhibit negative differential resistance (NDR) on a background M-I-M characteristics. The NDR feature occurs at $\sim$0.67 V at 300 K and shifts to a higher bias of 1.93 V at 90 K. When the tip is held in the middle region of the device, a coulomb blockade region is observed ($\pm\sim$0.3 V).

Changes in the electronic structure and properties of graphene induced by molecular charge-transfer

Interaction with electron-donor and -acceptor molecules such as aniline and nitrobenzene brings about marked changes in the D, G, G' and 2D bands of the Raman spectrum and the electronic structure of graphene, prepared by the exfoliation of graphitic oxide.

NbO₂ a Highly Stable, Ultrafast Anode Material for Li- and Na-Ion Batteries

Anode materials with fast charging capabilities and stability are critical for realizing next-generation Li-ion batteries (LIBs) and Na-ion batteries (SIBs). The present work employs a simple synthetic strategy to obtain NbO2 and studies its applications as an anode for LIB and SIB. In the case of the LIB, it exhibited a specific capacity of 344 mAh g–1 at 100 mA g–1. It also demonstrated remarkable stability over 1000 cycles, with 92% capacity retention. Additionally, it showed a unique fast charging capability, which takes 30 s to reach a specific capacity of 83 mAh g–1. For the SIB, NbO2 exhibited a specific capacity of 244 mAh g–1 at 50 mA g–1 and showed 70% capacity retention after 500 cycles. Furthermore, detailed density functional theory reveals that various factors like bulk and surface charging processes, lower ion diffusion energy barriers, and superior electronic conductivity of NbO2 are responsible for the observed battery performances.
