Metal particles were supported on TiO2 (Japan Aerosil, Evoke P25) to increase the metallic surface area via an impregnation method. As precursors for the metal particle, Pt(NH3)2(NO2)2 (Tanaka Kikinzoku Kogyo K.K.), RhCl3·3H2O (FUJIFILM Wako Pure Chemical Corporation), and PdCl2 (Wako Pure Chemical Industries) were used. The aqueous solution containing the precursor and support was stirred at 80 °C to evaporate the water content. After drying in an oven overnight to remove surface moisture completely, the powder was calcined at 350 °C for 2 h in a 10% H2/N2 flow. The metal content was adjusted to 1–10 wt%.

DAB, DMB, and o-PDA were purchased from Tokyo Chemical Industry. PdCl2, H2PtCl6•6H2O, RHCl3•3H2O, NaCl, and HCl (reagent grade, purchased from Wako Pure Chemical Industries) were used to prepare the initial solutions to be used in metal recovery experiments. An analytical-grade AgNO3 solution was purchased from Wako Pure Chemical Industries and used to determine the Cl -concentration in aqueous solution. All chemicals were used without further purification, and all experiments were performed at room temperature.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
