N Doped Activated Biochar from Pyrolyzing Wood Powder for Prompt BPA Removal via Peroxymonosulfate Activation

In the present study, nitrogen doped biochar (N-PPB) and activated (AN-PPB) were prepared used for removing bisphenol A (BPA) in water through activating peroxymonosulfate. It was found from results that N-PPB exhibited superior catalytic performance over pristine since could brought about abundant active sites to structure. The non-radical singlet oxygen (1O2) determined be dominant species responsible BPA degradation. Having pathway N-PPB/PMS system, degradation barely influenced by many external environmental factors including solution pH value, temperature, foreign organic, inorganic matters. Furthermore, AN-PPB had richer porosity than N-PPB, which showed even faster removal efficiency an adsorptive/catalytic synergy. finding of this study introduces a novel way designing hieratical structured catalysts effective organic pollutant water.
