Electrochemical properties of anodized copper hydroxide nanostructures
Here, we report room temperature growth of one-dimensional copper hydroxide, Cu(OH)2 nanostructures viz., nanoneedles (NNs), nanoleafs (NLs) and nanorods (NRs) from NaOH, LiOH and NaOH+ LiOH aqueous electrolyte solutions, respectively, employing a simple and cost-effective chemical anodization process. Structural elucidation and morphological evolution studies are elaborated thoroughly. Morphology inspired evolution of specific capacitance is estimated using cyclic-voltammogram and discharge measurements wherein, due to a relatively higher total charges and the least charge transfer resistance, in electrode with NRs morphology paved remarkable electrochemical performance compared to electrodes of NNs and NLs morphologies
Unprecedented “In Water” Imidazole Carbonylation: Paradigm Shift for Preparation of Urea and Carbamate
The first “In Water” imidazolecarbonylation of amine is described. A one pot reaction of carbonylimidazolide in water with a nucleophile provides an efficient and general method for the preparation of urea, carbamates and thiocarbamates. Use of an anhydrous solvent and an inert atmosphere could be avoided. Product precipitate out from the reaction mixture and can be obtained in high purity by filtration, resulting in a simple and scalable method
Current density enhancement in ZnO/CdSe photoelectrochemical cells in the presence of a charge separating SnO2 nanoparticles interfacing-layer
Improved Photoelectrochemical Cell Performance of Tin Oxide with Functionalized Multiwalled Carbon Nanotubes–Cadmium Selenide Sensitizer
Here we report functionalized multiwalled
carbon nanotubes (<i>f</i>-MWCNTs)–CdSe nanocrystals
(NCs) as photosensitizer in photoelectrochemical cells, where <i>f</i>-MWCNTs were uniformly coated with CdSe NCs onto SnO<sub>2</sub> upright standing nanosheets by using a simple electrodeposition
method. The resultant blended photoanodes demonstrate extraordinary
electrochemical properties including higher Stern–Volmer constant,
higher absorbance, and positive quenching, etc., caused by more accessibility
of CdSe NCs compared with pristine SnO<sub>2</sub>–CdSe photoanode.
Atomic and weight percent changes of carbon with <i>f</i>-MWCNTs blending concentrations were confirmed from the energy dispersive
X-ray analysis. The morphology images show a uniform coverage of CdSe
NCs over <i>f</i>-MWCNTs forming a core–shell type
structure as a blend. Compared to pristine CdSe, photoanode with <i>f</i>-MWCNTs demonstrated a 257% increase in overall power conversion
efficiency. Obtained results were corroborated by the electrochemical
impedance analysis. Higher scattering, more accessibility, and hierarchical
structure of SnO<sub>2</sub>-<i>f</i>-MWCNTs-blend–CdSe
NCs photoanode is responsible for higher (a) electron mobility (6.89
× 10<sup>–4</sup> to 10.89 × 10<sup>–4</sup> cm<sup>2</sup> V<sup>–1</sup> S<sup>1–</sup>), (b)
diffusion length (27 × 10<sup>–6</sup>), (c) average electron
lifetime (32.2 ms), and transit time (1.15 ms)
