Fully Understanding the Photochemical Properties of Bi₂O₂(CO₃)_1–<i>x</i>S_<i>x</i> Nanosheets

The photochemical properties of crystal facets with obviously distinct atomic and geometric structures have been studied widely to date. However, little work has been performed for two or more facets with very similar atomic and geometric structures. Herein, we mainly report the photochemical properties of {001} and {100} facets of Bi2O2(CO3)1–xSx with very similar atomic and geometric structures. The simulation and experimental results show that over {100} facets, sulfur prefers to substitute for the carbonate anion, leading to the formation of an interesting serpentine internal electric field that greatly inhibits the charge recombining of electrons and holes, which has rarely been demonstrated; over {001} facets, however, sulfur preferentially adsorbs in oxygen vacancies, which greatly reduces the surface energy of {001} facets, leading to 80% of the high-energy {001} facets exposed. As a result, the photochemical properties of nanosheets have been greatly improved. This study could help us to fully understand the photochemical properties of semiconductors

Hydrodynamic Behavior Analysis of Agitated-Pulsed Column by CFD-PBM

Recently, a newly designed type of energy-input extraction column, agitated-pulsed column (APC), has been achieved high mass-transfer efficiency due to the small-size droplets and high dispersed-phase holdup. In view of the lack of feasible population-balance-model (PBM) kernel functions in APC, parameter optimization is conducted by a simplified PBM method. Then the optimized PBM kernel functions are implemented in the computational fluid-dynamics (CFD) code to investigate local two-phase flow behaviors in a 25 mm APC. The results show that the CFD-PBM successfully predicts the drop-size distribution measured in the experiments. CFD-PBM also gives good prediction of Sauter mean diameter and dispersed-phase holdup. The local flow behaviors are illustrated to understand the effects of operating conditions on the hydrodynamic performance. This work demonstrates a possibility for prediction of drop-size distribution by the combination of simplified PBM and CFD simulation.</p
