Abstract
Advanced oxidation processes (AOPs) play a pivotal role in purifying contaminated water and securing drinking water safety. Transition metal-based materials are highly effective AOP catalysts, while their applications are limited by their poor stability in the oxidative environment. In this study, we developed a composite catalyst, molybdenum disulfide/ferric oxide (MoS2/Fe3O4), to evaluate its catalytic performance and explore its underlying mechanisms in peroxymonosulfate activation. The powder composite was successfully loaded onto an engineered wood substrate, creating a monolith wood@MoS2/Fe3O4 composite for large-scale practical applications. The engineered bulk catalyst exhibits exceptional versatility and stability in wastewater treatment, maintaining nearly 100% removal efficiency over continuous operation for 144 hours. These findings underscore the significant potential of wood-loaded nanomaterials for cost-effective wastewater treatment.
期刊介绍：
Nanoscale Horizons stands out as a premier journal for publishing exceptionally high-quality and innovative nanoscience and nanotechnology. The emphasis lies on original research that introduces a new concept or a novel perspective (a conceptual advance), prioritizing this over reporting technological improvements. Nevertheless, outstanding articles showcasing truly groundbreaking developments, including record-breaking performance, may also find a place in the journal. Published work must be of substantial general interest to our broad and diverse readership across the nanoscience and nanotechnology community.
