Gibbsite [α-Al(OH)3] is the solubility limiting phase for aluminum across a wide pH range, and it is a common mineral phase with many industrial applications. But the growth mechanism of...
A nonheme single-metal-site Mn-complex i.e. [Mn(N3Py2)H2O] (ClO4)2; where N3Py2 = N,N′-dimethyl-N-(2-(methyl(pyridin-2-ylmethyl)amino)-ethyl-N′-(pyridin-2-ylmethyl)ethane-1,2-diamine) displays electrochemical water oxidation ability in a wide pH range.
Manganese oxide coated carbon fibre paper electrodes (MnOx/CFP) exhibit promising water oxidation activities and stabilities for applications in alkaline, neutral and even acidic electrolytes.
Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate that the process are irreversible. The influence of the pH on the polarographic parameters was also studied. A UV spectrophotometric study was performed in the pH range 2-13. In basic media some variations in the absorption bands were observed due to the dissociation of the amidine group. A determination of the pK values was made by deconvolution of the spectra. Correlations of both the electrochemical parameters and spectrophotometric pK values with the Hammett substituent constants were obtained.
The development of a heterogeneous Fenton-like catalyst, possessing high degradation efficiency in a wide pH range, is crucial for wastewater treatment. The Fe-Mn-SiO2 catalyst was designed, and prepared by a...
