Review of DFT-simulated and experimental electrochemistry properties of the polypyridyl Row-1 Mn, Fe & Co, and Group-8 Fe, Ru and Os MLCT complexes
(Elsevier, 2022)Ruthenium had up to date been pivotal in electro- and photocatalytic applications involving reduction of CO2 and H2O, and dye-sensitized solar cells. Commercial applications would seek use of earth-abundant metals instead. ... -
Data to understand the nature of non-covalent interactions in the thiophene clusters
(Elsevier, 2021)We have reported herein the data to understand the nature and number of non-covalent interactions that stabilize the structures of the thiophene clusters. In addition, we have also provided the optimized Cartesian coordinates ... -
Polypyridyl copper complexes as dye sensitizer and redox mediator for dye-sensitized solar cells
(Elsevier, 2021)Developments on the application of polypyridyl-based copper complexes in dye-sensitized solar cells (DSSCs) are briefly discussed in this mini review. Copper complexes in solar cells are special in that they can be used ... -
Density functional theory calculated data of the iodomethane oxidative addition to oligothiophene-containing rhodium complexes – importance of dispersion correction
(Elsevier, 2021)Electronic and free energy data of density functional theory calculated optimized geometries of the reactants, transition state of the oxidative addition reaction and different reaction products of the [Rh(RCOCHCOCF 3 ... -
Free energy and enthalpy data of neutral and protonated clusters in the solvent phase
(Elsevier, 2021)Structures of neutral and protonated acetonitrile in the sol- vent phase are important to describe proton behavior and to calculate thermodynamic quantities related to the solva- tion of ions or molecules in acetonitrile. ... -
QTAIM analysis dataset for non-covalent interactions in furan clusters
(Elsevier, 2021)Furan clusters are very important to understand the dynam- ics and properties of the furan solvent. They can be used combined with quantum cluster equilibrium theory to theo- retically determine the thermodynamics properties ... -
Metal exchange of ZIF-8 and ZIF-67 nanoparticles with Fe(II) for enhanced photocatalytic performance
(American Chemical Society, 2021)Zeolitic imidazolate frameworks (ZIFs), such as ZIF-8 and ZIF-67, were found to be efficient catalysts. However, ZIFs are not used much in photocatalysis due to their low photocatalytic activity for most reactions. The ... -
Isotherm, kinetic, thermodynamics and reusability data on the adsorption of antidepressant onto silver nanoparticle-loaded biowaste
(Elsevier Inc., 2021)There has been an increase in the use of antidepressant drugs owing to significant economic challenges across the globe. Consequently, the increase in production of such drugs has impacted pharmaceutical pollution of ... -
Optimized CO2 capture of the zeolitic imidazolate framework ZIF‑8 modified by solvent-assisted ligand exchange
(American Chemical Society, 2021)Zeolitic imidazolate frameworks, like ZIF-8 and related structures, have shown great potential for the capture of carbon dioxide. Modifying their structure by exchanging part of the constituent organic ligands is a proven ... -
Comparison of the spectroscopically measure catalyst transformation and electrochemical properties of Grubbs' first- and second-generation catalysts
(American Chemical Society, 2021)According to UV–vis spectroscopy (0.10 mM, CH2Cl2 at 25 °C), the catalyst transformation (which could possibly include ligand dissociation with active catalyst formation, dimer formation, and decomposition) rate constants ... -
