Prof. Jie Ma’s Team Published in Advanced Functional Materials:Bacillus Cereus-derived Hollow Carbon Rods

Recently, a research paper titled "Bacillus Cereus-derived Hollow Carbon Rods/Oxygen-Vacancy-Rich Co₃O_4-x Nanosheets by Biomineralization Strategy for Boosting Lead Ions Capture," authored by the team of Professor Jie Ma from CESE has been published in Advanced Functional Materials. This study innovatively utilized the "biomineralization" function of Bacillus cereus to successfully construct a composite electrode consisting of hollow-derived carbon rods (LY) coated with oxygen-vacancy-rich Co₃O_4-x nanosheets (LY-Co₃O_4-x). Under a working voltage of 1.60 V, LY-Co₃O_4-x demonstrated exceptional Pb²⁺ removal performance, with an adsorption capacity of up to 78.7 mg g⁻¹ and an adsorption rate of 2.62 mg g^-1 min^-1, surpassing the vast majority of reported electrode materials. This discovery opens up a new pathway for constructing metal oxides using microorganisms and regulating their electrochemical activity.
