Porous Aromatic Framework as an Efficient Metal-Free Electro-catalyst for Non-enzymatic H2O2 Sensing

Porous Aromatic Framework as an Efficient Metal-Free Electro-catalyst for Non-enzymatic H2O2 Sensing
Jia Liu, Hao Ren, Yue Gu, Rongrong Yuan, Guangshan Zhu
A porous aromatic framework (referred as PAF-39) based on tetrakis(4-(9H-carbazol-9-yl)phenyl)methane has been designed and synthesized by oxidative coupling polymerization. PAF-39 exhibits high surface area and high heat of adsorption (Qst) of CO2. Especially, the PAF material was applied for non-enzymatic H2O2 sensing. Taking the stage: A robust porous aromatic framework (PAF-39) was designed and synthesized based on tetrakis(4-(9H-carbazol-9-yl)phenyl)methane by FeCl3-trigged oxidative coupling polymerization. PAF-39 has high skeleton stability, high surface area and high CO2 absorption capacity. PAF-39-modified glassy carbon electrode (GCE) was applied as sensor in the detection of H2O2. The modified electrode has good analytical performances of wide linear range and high sensitivity.
