dc.description.abstract | Mass-production simple synthesis of self-assembled oval-shaped iron oxide nanparticles was achieved by 24 h solvothermal treatment at 100 degrees C using a ferric nitrate precursor in ethanol media. The Brunauer-Emmett-Teller (BET) surface area was measured to similar to 100 m(2)/g, and the XRD pattern results showed a hematite crystalline structure. With increasing heat-treatment temperature from 300 to 700 degrees C under a 4% H-2/96% Ar atmosphere for 3 h operation, the oval-shaped morphology of the iron oxide nanoparticles (NPs) was disrupted, leading to a sharp decrease in BET surface area with mixed hematite, magnetite, and wustite phases. Taking into consideration H2O2 as a decomposition catalyst of iron oxide NPs, photo-Fenton degradation of methylene blue (MB) was investigated. The results showed the highest apparent rate constant of 5.36x10(-3) min(-1) (r(2) = 0.996) under the 0.2 g alpha-Fe2O3 powder dosage and 0.5 M H2O2 loading conditions; however, all of the phase-transformed alpha-Fe2O3 NPs showed smaller apparent rate constants. Notably, 50 L pilot-scale photo-Fenton reaction based on the optimal batch-scale MB-degradation conditions could be of significant potential catalytic utility in advanced oxidation processes (AOPs) for practical water/wastewater applications. | - |
