“…The photoabsorption in the range around 450 nm originated from d−d transition of Rh, 1 A 1g → 2 T 2g . 11,34 The photoabsorption in the range from visible to UV light regions probably originated from the charge transfer from Rh 3+ to the conduction band of semiconductors, which depends on the semiconductor oxide.…”

A rhodium(III) ion (Rh3+)-modified TiO2 (Rh3+/TiO2) photocatalyst, prepared by a simple adsorption method and exhibiting high levels of photocatalytic activity in degradation of organic compounds, was investigated by using X-ray absorption fine structure (XAFS) measurements, (photo)electrochemical measurements, double-beam photoacoustic (DB-PA) spectroscopic measurements, and photoluminescence measurements. Based on the results, the features of the Rh3+ modifier and the working mechanism of the Rh3+/TiO2 photocatalyst are discussed. XAFS measurements revealed that the Rh3+ species were highly dispersed and almost atomically isolated on TiO2. The (photo)electrochemical measurements, DB-PA spectroscopic measurements, and photoluminescence showed a unique bifunction of the Rh3+ modifier as a promoter for O2 reductions and an electron injector to the conduction band of TiO2 for response to visible light. The reasons for the Rh3+/TiO2 photocatalyst exhibiting higher levels of photocatalytic activity than those of TiO2 photocatalysts modified with other metal ions are also discussed on the basis of obtained results.

“…This method was extensively studied for the recovery of noble metals, mainly gold [29,30] and platinum [31][32][33]. Bromide anions were selected as the complexing agent because the stability of the complex ion is lower when compared to the chloride one [34,35]. This offers, at least theoretically, the possibility of adsorption and subsequent reduction of Rh(III) to the metallic form as it was observed in the case of Au(III) chloride complex ions [36][37][38][39].…”

In the paper, the mechanism of the process of the Rh(III) ions adsorption on activated carbon ORGANOSORB 10—AA was investigated. It was shown, that the process is reversible, i.e., stripping of Rh(III) ions from activated carbon to the solution is also possible. This opens the possibility of industrial recovery of Rh (III) ions from highly dilute aqueous solutions. The activation energies for the forward and backward reaction were determined These are equal to c.a. 7 and 0 kJ/mol. respectively. Unfortunately, the efficiency of this process was low. Obtained maximum load of Rh(III) was equal to 1.13 mg per 1 g of activated carbon.
