文摘
- •
LaCoO3 provides heterogeneous MPS decomposition with low Co leaching at pH > 7.
- •
Herbicide completely removal highly depends on MPS concentration (>10−4 M).
- •
Catalyst load does not significantly exert effect on MPS decomposition.
- •
Catalyst showed no loss of activity after 5 reusing cycles.
- •
Solid characterization led to a nanosized spherical LaCoO3 (rhombohedral phase).
