The present study involves the synthesis, characterization, and catalytic application of ruthenium nanoparticles (Ru NPs) supported on plastic-derived carbons (PDCs) synthesized from plastic wastes (soft drink bottles) as an alternative carbon source. PDCs have been further activated with CO and characterized by various analytical techniques. The catalytic activity of Ru@PDC for the reduction of potassium hexacyanoferrate(III), (K[Fe(CN)]), and new fuchsin (NF) dye by NaBH was performed under mild conditions. The PDCs had spherical morphology with an average size of 0.5 μm, and the Ru NP (5 ± 0.2 nm) loading (4.01 wt %) into the PDC provided high catalytic performance for catalytic reduction of ferrocyanate(III) and NF dye. This catalyst can be recycled more than six times with only a minor loss of its catalytic activity. In addition, the stability and reusability of the Ru@PDC catalyst are also discussed.
本研究涉及以塑料废弃物（软饮料瓶）合成的塑料衍生碳（PDC）为替代碳源负载钌纳米颗粒（Ru NPs）的合成、表征及催化应用。PDC已用CO进一步活化，并通过各种分析技术进行了表征。在温和条件下，对Ru@PDC催化硼氢化钠还原铁氰化钾（K[Fe(CN)]）和新福林（NF）染料的活性进行了研究。PDC呈球形，平均尺寸为0.5μm，向PDC中负载的Ru NP（5±0.2nm）（4.01 wt%）对铁氰酸盐（III）和NF染料的催化还原具有高催化性能。该催化剂可循环使用六次以上，且催化活性仅有轻微损失。此外，还讨论了Ru@PDC催化剂的稳定性和可重复使用性。
