Peroxidase mimicking of heteroatom-codoped carbon and the application in colorimetric sensors Sadaf Saeedi Garakani Department of Materials and Environmental Chemistry, Stockholm University, Stockholm 10691, Sweden In this study, we aim to investigate poly (ionic liquid)s-based N, X-heteroatom codoped porous carbon membrane with X standing for B, P, or S. By heteroatom doping, the properties of the carbon materials can be significantly changed in contrast to nitrogen-doped counterpart. The introduction of heteroatoms of different sizes and electronegativity into the carbon matrix can induce charge and spin redistribution among the neighboring carbon atoms, leading to the modification of electronic properties and other chemical activities for many applications. Amongst the doping agents, nitrogen doping and co-doping are both beneficial options since forming more active sites for catalytic activities in the network of carbon atoms which enable them the enzyme mimetic performance. N, X (X = B, P, and S) heteroatom codoped porous carbon materials were successfully synthesized via vacuum carbonization of hybrid porous PILs membranes, and their properties were characterized. N, X-carbon materials showed catalysis capability toward the oxidation of TMB in the presence of H 2 O 2 to create a blue solution with an absorption maximum at 652 nm. In this project, we could synthesize metal-free peroxide mimicking catalysts to provide better stability.
