Cerium coordination polymer (CeCP) was synthesized with 1,3,5-benzenetricarboxylic acid as the ligand. By using the carboxyl groups on the surface of CeCP as the anchors, platinum nanoparticles were formed on CeCP forming the composite [email protected] The composite was characterized by measuring TEM images, and EDS and XPS spectra. [email protected] was used to catalyze the oxidation of 3,3,5,5-tetramethylbenzidine in the presence of H2O2. The activity assay demonstrated that [email protected] exhibited an activity similar to that of horseradish peroxidase, but with a much higher activity. [email protected] was utilized to detect nitroaniline, being able to detect trace amount of nitroaniline (>3.125 × 10−4 mg/mL). View Full-Text
