THE ADSORPTION AND BONDING OF H₂S ON THE α-FeOOH(110) SURFACE

Abstract

The electronic structure of H 2 S adsorbed on the goethite (110) surface has been studied by ASED-MO cluster calculations. We have studied both the perpendicular and the parallel H 2 S molecular adsorption on the FeOOH(110) surface. We have analyzed the adsorption configuration energies including rotation. The parallel species does not rotate during adsorption and corresponds to the most stable configuration. We have also studied the bonding contributions for the minimum energy configuration and the density of states plots.

Photodegradation of Rhodamine B in α-FeOOH/oxalate under light irradiation

“…a-FeOOH, which presents a large surface area and stable chemical properties, can be used as an adsorbent and catalyst in water treatment. [17][18][19] Hence, the preparation of highly active a-FeOOH is important in modern environmental chemistry. Previous studies on pollutant photodegradation in the a-FeOOH system generally involve the use of highly crystalline a-FeOOH as photo-Fenton catalysts.…”
