A natural manganese ore as a heterogeneous catalyst to effectively activate peroxymonosulfate to oxidize organic pollutants
文献摘要：
Heterogeneous transition metal catalysts are indispensable in improving environmental pollution.How-ever,their fabrication is often costly and cumbersome,and they can easily pollute the environment.This study proposed using a natural Gabonese ore(GBO)containing MnxOy and FexOy as catalysts to degrade orange Ⅱ(OⅡ)via peroxymonosulfate(PMS)activation.The GBO+PMS system exhibited extraordinarily high stability and catalytic activity towards OⅡ elimination(92.2％,0.0453 min-1).The reactive oxygen species(ROS)generated in the system were identified using radical scavenging tests and electron spin-resonance(ESR)analysis.Singlet oxygen(1O2)represented the dominant reactive species for OⅡ degrada-tion,while the system presented a lower reaction energy barrier and was effective in a broad pH range(2-10).This work also proposed the activation mechanism for the GBO+PMS system and OⅡ degrada-tion pathways.This study revealed a new approach for exploring inexpensive,eco-friendly,efficient,and stable heterogeneous transition metal catalysts.
