Description	Journal: Nanotechnology Indoor formaldehyde removal is of great significance to reduce public health risk. Herein, we report a facile method for preparing N-doped nanoporous carbon through direct carbonization of MOFs (ZIF-8) to remove harmful formaldehyde (HCHO). The prepared N-doped nanoporous carbon exhibited uniform morphology and large specific surface area. Moreover, the forms of N-functional groups on the N-doped nanoporous carbon had a dominant effect on its formaldehyde adsorption activity. As a result, HCHO adsorption capacity of the optimized N-doped nanoporous carbon was ca. 5 times higher than that of the commercial activated carbon. The detail HCHO adsorption process including physical adsorption and chemical adsorption were also confirmed through the in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). In addition, it should be noted that the N-doped nanoporous carbon exhibited high stability for formaldehyde adsorption even after 6 adsorption cycles, indicating its good recyclability for long-term application. This study is expected to pave a way for expanding the environmental applications of the N-doped nanoporous carbon.
