Summary:Nitrogen oxide and its derivatives, including nitroaromatic hydrocarbons and various other nitro compounds, are commonly used in industrial applications such as synthesizing drugs, dyes, pesticides, and explosives. However, these compounds are also highly toxic to the environment. Their long-term accumulation can significantly affect air and water quality and disrupt ecosystems. Thus, efficiently converting these harmful compounds into more valuable products through catalytic processes is an urgent challenge in chemical catalysis. In this regard, polyoxometalates (POMs) have emerged as promising inorganic molecular catalysts for the reduction of nitrogen oxide and its derivatives. Their unique structure, excellent redox properties, and versatile catalytic abilities contribute to their effectiveness. This review provides an overview of recent advancements in the POM-catalyzed reduction of nitrogen oxide and its derivatives, focusing on reducing nitroaromatic hydrocarbons and nitrogen oxides. Additionally, we discuss the reaction mechanisms involved in the catalytic process, explore the potential of POMs' structural features for the rational design and optimization of catalytic performance, and highlight future directions for developing POM-based catalysts. In-depth understanding of the optimization of the catalytic reduction of nitrogen oxide and its derivatives using a structure regulation strategy of polyoxometalates.
Bibliography:Prof. Dr Jia-Jia Chen received his BSc and PhD from the Department of Chemistry at Xiamen University in 2009 and 2014, respectively. Then he carried out his postdoctoral research with Prof. Leroy Cronin at the University of Glasgow (2015-2018). He started his independent research in December of 2018 and built his own research team at Xiamen University. His group research interests mainly include the following two aspects: (1) the structural evolution and self-assembly of redox-active materials with multi-electron redox ability. Our group can build operand spectroscopy techniques to reveal the self-assembly behaviors of clusters with multi-electron redox ability. This will, in turn, help us design interesting materials rationally. (2) Functional electrolytes and the related physical electrochemistry in soluble and solid states. Metal-oxo clusters can exist in aqueous, nonaqueous, and solid-state electrolytes/polymer electrolytes, which will play important roles in solar/thermal/electrical-driven energy storage and conversion systems.
