CeO2 and AuCeO2 were prepared following the methodology previously described by our group [20 (link),37 (link)]. To obtain I–AuCeO2, AuCeO2 was silylated by stirring a suspension of dried AuCeO2 (314.5 mg) in 6 mL of an anhydrous toluene (Sigma-Aldrich, Madrid, Spain) solution containing 3–(iodopropyl)trimethoxysilane (61 mg, 0.34 mmol) (Sigma-Aldrich, Madrid, Spain) for 3 h at 85 °C. Afterwards, the mixture was allowed to cool at room temperature. Then, I–AuCeO2 was filtered and sequentially washed with toluene (3 × 100 mL), acetone (3 × 100 mL) and diethyl ether (2 × 100 mL) (all solvents from Sigma-Aldrich, Madrid, Spain), and later allowed to dry at room temperature under reduced pressure. The material was obtained as a brown solid, and the presence of iodopropyl groups was determined by FT-IR spectroscopy (Jasco FT-IR-460 PLUS, Easton, MD, USA), while the content of C was determined by chemical combustion analysis in a FISONS CHNOS analyzer (Fisons EA-1108-CHNS-O, Milano, Italy).

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.
