摘要

在这项研究中,通过简单的共沉淀法合成了圆盘状的硫化铜纳米颗粒(cu - nps),并将其用作光催化剂,用于将大理石粉尘中的碳酸盐还原为乙酸(AcOH)。在单色光(525 nm)下,用cu - nps在过氧化氢-水混合物中进行光催化反应。对溶剂组成、光源、催化剂浓度、反应时间等关键参数进行了优化,得到了AcOH的最大产率。通过自由基清除实验研究了反应机理。在另外两种现实生活中的碳酸盐废料,即白垩粉和碳酸盐水垢上,进一步测试了该方法的实际适用性。

Photocatalytic upcycling of marble waste into acetic acid by copper sulfide nanoparticles†

In this study, disk-shaped copper sulfide nanoparticles (CuS-NPs) were synthesized via a simple co-precipitation method and used as a photocatalyst for the reduction of carbonate species derived from marble dust into acetic acid (AcOH). The photocatalytic reaction was carried out under monochromatic light (525 nm) in a hydrogen peroxide–water mixture using CuS-NPs. Key parameters such as solvent composition, light source, catalyst concentration and reaction time were optimized to get the maximum yield of AcOH. The reaction mechanism was investigated using radical scavenging experiments. The practical applicability of the approach was further tested on two additional real-life carbonate waste materials, i.e., chalk dust and carbonate scale.
