This work aimed to valorize vine shoots, for water treatment applications by investigating hydrochar materials in catalytic ozonation. For this purpose, a vine-pruning waste derived catalyst was synthesized via hydrothermal treatment at 200 °C, previous a cobalt impregnation step. The catalytic ozonation of the pharmaceutical ibuprofen showed 47 % higher degradation rate than single ozonation. However, the catalytic efficiency was reduced increasing the catalyst dose due to dissolved organic matter released during reaction. To address this issue, several chemical post-treatments were tested without effectiveness. Nevertheless, in the presence of a post-treated pyrolyzed catalyst at 550 °C (0.25 g/L), 86 % ibuprofen removal within just 1 min was achieved using 5 mg/L of ozone. The increase in BET surface area and the adsorption of ibuprofen on the material observed suggest a synergistic effect of both processes. Additionally, the effectiveness of the system was confirmed in a real aqueous matrix.

葡萄藤修剪废料衍生催化剂，用于通过臭氧化从水中降解布洛芬


这项工作旨在通过研究催化臭氧反应中的水炭材料，使藤芽在水处理应用中增值。为此，在 200 °C 的水热处理之前，先进行钴浸渍步骤，合成了葡萄藤修剪废料衍生的催化剂。药物布洛芬的催化臭氧化比单一臭氧化的降解率高 47%。然而，由于反应过程中释放的溶解有机物，催化效率降低，催化剂剂量增加。为了解决这个问题，测试了几种化学后处理，但没有效果。然而，在 550 °C （0.25 g/L） 后处理热解催化剂存在的情况下，使用 5 mg/L 臭氧在短短 1 分钟内实现了 86% 的布洛芬去除。BET 表面积的增加和布洛芬对观察到的材料上的吸附表明这两个过程具有协同作用。此外，该系统的有效性在真实的水性基质中得到了证实。
