Abstract

Catalytically active coatings on titanium are synthesized via plasma electrolytic oxidation (PEO) in aqueous electrolytes containing sodium phosphate and tungstate, in addition to iron chelate complexes with EDTA. Analysis of EDX, XPS, and XRD data show the PEO coatings contained titanium dioxide and amorphous tungstates and/or phosphates of iron. High concentrations of phosphorus (up to 6 at %) promote amorphization. Testing the PEO catalysts reveals their activity in the oxidative desulfurization (ODS) of thiophene and dibenzothiophene with hydrogen peroxide and atmospheric oxygen.

基于磷、钨、铁氧化物混合等离子体电解氧化层的过氧化物和好氧脱硫催化剂

采用等离子体电解氧化（PEO）技术，在含磷酸钠、钨酸钠和EDTA铁螯合物的水溶液中合成了具有催化活性的钛涂层。EDX， XPS和XRD数据分析表明，PEO涂层含有二氧化钛和无定形钨酸盐和/或铁磷酸盐。高浓度的磷（高达6%）促进非晶化。PEO催化剂在过氧化氢和常压下氧化脱硫噻吩和二苯并噻吩的活性得到了验证。
