Abstract
Lignin, as the most abundant natural aromatic compound, holds immense potential for the production of fuels and fine chemicals, making it a focal point in green chemistry. The efficient depolymerization of lignin hinges on the discovery of catalysts that are not only efficient but also stable and recyclable. Understanding the structure-function relationships and mechanisms governing lignin-catalyst depolymerization is paramount for its effective valorization. Polyoxometalates (POMs) have emerged as promising candidates due to their versatile structural composition and design flexibility. In this review, we explore the utilization of POMs in various methods of lignin transformation, encompassing oxidative catalysis, reduction catalysis, and photocatalysis. By summarizing these approaches, we aim to elucidate the current trends and challenges in the depolymerization of lignin using POMs.
期刊介绍：
The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
