An analytical chemistry experiment at an intermediate level is presented in this work, achieving the detection of chemiluminescence (CL) on a paper-based device. Using copper nitrate and benzene-1, 3, 5-tricarboxylic (BTC) acid in a metal-organic frameworks (MOFs) synthesis reaction, Cu-BTC with a catalytic effect was synthesized and loaded onto the paper's surface. Due to the catalytic effect of Cu-BTC in a luminol-H2O2 CL system, trace H2O2 can be detected. This exercise can train students' practical ability in comprehensive experiments. It can also improve the intuitive ability of normal students to better grasp experimental data processing.

Key words: Chemiluminescence, Paper-based device, Hydrogen peroxide, Metal organic frameworks
