Fig. 7. PEC water oxidation performance of the Ag3PO4 microcrystalline film photoanodes: (a) The dependence of photocurrent density minus dark current density (Jlight − Jdark) on applied potential. Inset shows an enlarged view of the potential range from 0.330 to 0.405 V vs. Ag/AgCl. NA...
The dimensions of the unit cell are: a=6.259 plus or minus 0.005, b=7.124 plus or minus 0.005, c=10.990 plus or minus 0.005 A for CaCrO4Cl, and a=6.185 plus or minus 0.002, b=6.983 plus or minus 0.002, c=10.816 plus or minus 0.004 A for CaPO4Cl. The crystal structures of ...
Of particular interest was the requirement of carbon dioxide release during the setting reaction to obtain Ca9− x (HPO4)1−1.5 x (PO4)5−2.5 x (CO3)3.5 x (OH)1 + 1.5 x with a fixed carbonate content. Results indicated that a compromise is necessary with respect ...
at 23 °C for a colorless crystal of dimensions 0.135 × 0.063 × 0.027 mm on a Siemens Smart-CCD diffractometer on convergence gave final values ofR1= 0.0429,wR2(F2) = 0.0906, GOF = 1.068, residual electron density between −0.59 and 0.69 e Å−3. ...
The difference between the initial and final pH was measured, and the point where ΔpH = 0 was taken as the point of zero charge (Figure 3). The pHZPC of the alginate–clay bio-nanocomposite used was found to be 6.2 (Figure 3). This figure shows that the bio-nanocomposite surface ...
The electrolytic resistance Rel is the first intercept of the semicircle with the x‐axis, while the second intercept minus the electrolytic resistance Rel represents the charge transfer ...
