α-MnO 2 activation of peroxymonosulfate for catalytic phenol degradation in aqueous solutions

Several α-MnO2 catalysts in the forms of nanosphere, nanorod and nanowire were synthesized, characterized and tested in heterogeneous activation of peroxymonosulfate for phenol degradation in aqueous solutions. The α-MnO2 materials exhibited varying activities in activation of peroxymonosulfate to p...
