Facilitating the Fe( iii )/Fe( ii ) redox cycle with organic pollutants to enhance the heterogeneous Fenton-like catalytic performance of iron-containing catalysts

Key Points

• The aim is to investigate how organic pollutants facilitate the redox cycle in Fenton-like systems to enhance catalytic performance.
• Utilized MIL-100-Fe as the iron-containing catalyst
• Evaluated the impact of methylene blue (MB) on the Fe(iii)/Fe(ii) redox cycle
• Measured hydroxyl radical (˙OH) generation
• Methylene blue effectively promoted the reduction of Fe(iii) to Fe(ii)
• Increased production of hydroxyl radicals (˙OH) was observed
• Boosted catalytic performance of the iron-containing catalyst was achieved
