Fenton Reaction Catalyst

In a heterogeneous Fenton system, metal catalysts fixed on a solid phase surface are used instead of the traditional Fe²⁺ in Fenton reactions to activate H₂O₂ and generate hydroxyl radicals (·OH) for pollutant removal. High-valent metals at the solid-liquid interface are reduced to low-valent states by H₂O₂, enabling the recycling of the catalyst and ensuring the continuous progress of the reaction (see equations 1-3).

≡Mn+ + H2O2 → ≡M(n+1)+ +·OH + OH－（1）
≡M(n+1)+ +H2O2 → ≡Mn+ + H2O·+ H+ （2）
H2O·+ ≡M(n+1)→ ≡Mn+ + H+ + O2 （3）

Compared to traditional Fenton reactions, heterogeneous Fenton technology significantly broadens the applicable pH range, avoids the production of iron sludge, and allows for the reuse of the catalyst.

product details

Advantage

1: This product uses a porous composite material as the catalyst carrier, which has high mechanical strength and incorporates various non-leachable catalytic components, enhancing the catalytic activity and stability of the catalyst. The high-temperature sintering technology ensures high utilization and strong adhesion of the active components, effectively reducing the loss rate of the catalytic filler, preventing secondary pollution, and extending the service life.

2: This product ensures the sustained high efficiency of the Fenton reaction catalyst through extensive testing and engineering applications, selecting appropriate carriers and active components for the catalytic filler.

3: By selecting suitable carriers and catalytic components, this product improves the catalytic activity and adaptability to the pH of the reacting wastewater, thereby widening the pH range of the reaction to some extent.

4: This product replaces the addition of ferrous ions in traditional Fenton processes, avoiding the production of large amounts of iron sludge and preventing secondary pollution, significantly improving the shortcomings of traditional Fenton methods.
