Abstract A simpler cost-effective method for the isolation of magnetically separable ‘self-doped iron oxide nanocarbons’ (FeO-NC) from waste printer ink (used as a carbon source material which is available free of cost) is discussed here. The process involves carbonization of waste printer ink in a muffle furnace at ~600 °C to obtain FeO-NC. The as-prepared FeO-NC has been investigated as an efficient heterogeneous catalyst for the long-known important organic reaction involving transformation of styrene to benzaldehyde in a quantitative yield (~70%). Importantly, FeO-NC were magnetically separable along with good recyclability, which supports the sustainability of reported process.

废打印机墨水将磁性可分离氧化铁掺杂纳米碳用于苯乙烯氧化的可持续性可行性

摘要 这里讨论了一种从废打印机墨水（用作碳源材料，可免费获得）中分离磁性可分离“自掺杂氧化铁纳米碳”（FeO-NC）的更简单的成本效益方法。该过程包括在约 600 °C 的马弗炉中碳化废打印机墨水以获得 FeO-NC。所制备的 Fe3O-NC 已被研究作为一种有效的多相催化剂，用于长期已知的重要有机反应，包括以定量产率 (~70%) 将苯乙烯转化为苯甲醛。重要的是，Fe3O-NC 是磁性可分离的，并且具有良好的可回收性，这支持了所报告过程的可持续性。
