Recently, the latest research results of Professor Zhu Junjiang of our School of Chemical   Engineering and Science on “In-situ template formation method to synthesize hierarchically porous carbon for electro catalytic reduction of 4-nitrophenol” were adopted by the internationally renowned journal Carbon (2021, 184,596-608, IF=9.594).

This study constructs a superior and simple preparation method for multi-stage hole carbon materials. Its core idea is using metal nitrates as a template agent precursor, in the calcium titanium mineral template agent generation process. On the one hand, the gas produced by nitrate decomposition can promote the formation of oxygen-containing energy groups on the carbon surface. On the other hand, the metal oxide migration composite process leaves meso-holes and microporous porous, and by etching to remove the calcium-titanium particle template agent, the synthesis of high-ratio surface area carbon material with microporous-meso-porous pores is achieved. In addition, changing the type of carbon precursor adjusts the oxygenated energy group content of porous carbon surfaces. The multi-stage hole carbon material which is made through the process is used to catalyze the reduction of 4-nitrophenol reaction and the performance of it turns out to be excellent, showing the application prospects of multi-stage hole carbon material in electro catalytic method to eliminate environmental pollutants.
