Ultralong MnO2 nanowires, which can effectively catalyze H2O2 to generate radicals for degrading methylene blue (MB) at low temperature (5.0 °C), are prepared by hydrothermal method. The MnO2 nanowires catalytically degrade 98.1% of MB within 30 min and degradation efficiency is about 93.0% after 5 cycles at 5.0 °C. The yield of ·OH and ·O2− radicals within 30 min is 39.33 $${\text{mg}}\;{{\text{g}}_{{\text{Mn}}{{\text{O}}_2}}}^{{...
Multifunctional catalysts are highly attractive for green oxidation process integrating excellent conversion and selectivity with high separability and recyclability. In this regards, a facile method is developed to fabricate yolk–shell microspheres consisting of Fe3O4 cores, mesoporous CeO2 shells and loaded Pd nanoparticles. Microspheres with 2.6 % Pd loading exemplify excellent catalytic activity...
