Das, Sumit Kumar; Bhattacharya, Tara Shankar; Chowdhury, Joydeep published an article about the compound: Pyridine-4-thiol( cas:4556-23-4,SMILESS:SC1=CC=NC=C1 ).Recommanded Product: Pyridine-4-thiol. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:4556-23-4) through the article.

Reported the wavelength-scanned (WS) SERS spectra of 4-mercaptopyridine mols. (4-MPy) adsorbed on Au nanoparticles immobilized in a Langmuir Reverse Schaefer (L-RSh) film matrix of 5CB mols. The WS-SERS spectral profile exhibited an increment in the intensity of the enhanced Raman bands of 4-MPy with an increase in the wavelength of the excitation laser source. The rationale behind the exptl. observations was supported by the simulated extinction spectra and the enhancement factor measurements of the modeled systems using the T-matrix formalism. The SERS intensity fluctuations in the band located at 1000 cm-1 for the 4-MPy mol., as obtained from 3 different locations in the L-RSh film substrate, were analyzed. Depending on the spatial locations of the substrates, the intensity fluctuations of the abovementioned band exhibit both Poisson and Gaussian distributions but the maximum number of probe mols. that can reside in the scattering areas under study cannot exceed 16. Probably the origin of SERS from single/few mols. or from the ensemble-averaged system cannot be inferred from the statistical distributions of the Raman intensity fluctuations. The present exptl. observations also revealed the relation between the near-field plasmonic behaviors of the substrate with the corresponding far-field SERS spectra of the 4-MPy mol.

Thanks to its larger surface and free volume, hollow nanostructure and nanomaterials are one kind of highly desirable electrodes for efficiently enhancing sodium-ion battery performance, especially at high rate. Herein, a design is demonstrated of hierarchical semi-open hollow structure, assembling with molybdenum selenide (MoSe2) nanosheets embedded on the nitrogen doped carbon matrix. The unique hollow structure can not only enable sufficient electrode/electrolyte interaction and fast electron transportation, but also suppress volume expansion during the insertion/extraction of sodium ion. As a direct outcome, the MoSe2/carbon anode exhibits excellent cycling and rate performance with a specific capacity of 431 mAh g-1 at 200 mA g-1, maintaining 87.7% capacity after 120 cycles. Notably, a discharge capacity of 199.1 mAh g-1 can be achieved even at an ultra-high c.d. of 20 A g-1, indicating quick Na+ storage ability. The results may open a new way to realize high-rate anode for ion battery applications.

Author is Rohloff, Martin; Anke, Bjoern; Kasian, Olga; Zhang, Siyuan; Lerch, Martin; Scheu, Christina; Fischer, Anna.

Anion substitution is an emerging strategy to enhance the photoelectrochem. performance of metal oxide photoelectrodes. In the present work, the effect is investigated of fluorine incorporation on the photoelectrochem. water oxidation performance of BiVO4 and Mo:BiVO4 thin film photoanodes. The BiVO4 and Mo:BiVO4 thin film photoanodes were prepared by a straightforward organometallic solution route involving dip coating and subsequent calcination in air. Fluorine modification was realized by applying a soft and low-cost solid-vapor reaction route involving fluorine-containing polymers and an inert gas atm. leading to novel F:BiVO4 and F/Mo:BiVO4 thin film photoanodes with substantially increased photoelectrochem. water oxidation properties. Deposition of the cobalt phosphate (CoPi) water oxidation catalyst allowed further enhancement of the photoelectrochem. performance. While Mo doping mainly improves light-harvesting, charge transport, and charge separation efficiencies, F modification was demonstrated to primarily affect the charge transfer efficiency at the semiconductor-electrolyte interface, thereby leading to a photocurrent increase of 40 and 21% upon fluorination of the BiVO4 and Mo:BiVO4 photoanodes, resp., and an applied bias photon-to-current efficiency increase of 35 and 5%, resp. It is demonstrated that cation and anion co-doping in BiVO4 as demonstrated for Mo and F allows combining the photoelectrochem. relevant benefits associated with each type of dopant.
