Abstract

Due to its unique properties, manganese dioxide (MnO₂) has been widely used in various environmental applications. However, its efficiency is not ideal, which limits its further applications. Fortunately, facet engineering has become an important strategy for improving its efficiency. This review aims to summarize the recent research progress in the facet engineering of MnO₂. Firstly, the synthesis strategies of MnO₂ with specific exposed facets are introduced in detail. Subsequently, the facet dependent properties of MnO₂ crystals including surface energy, exposed atoms and electronic structure are concisely discussed. Furthermore, the applications of faceted MnO₂ in terms of organic pollutant removal, air pollutant removal, heavy metal removal, energy production and storage are systematically reviewed. Finally, the remaining challenges are summarized and the perspectives for future research are stated. These are believed to provide guidelines for the development of facet engineering of MnO₂ crystals.

二氧化锰的刻面工程：提高效率的重要策略

二氧化锰（MnO）因其独特的性能，已被广泛应用于各种环境领域。然而，它的效率并不理想，这限制了它的进一步应用。幸运的是，刻面工程已成为提高其效率的重要策略。本综述旨在总结氧化锰刻面工程的最新研究进展。首先，详细介绍了具有特定暴露面的氧化锰的合成策略。随后，简要讨论了氧化锰晶体与刻面相关的特性，包括表面能、暴露原子和电子结构。此外，还系统回顾了刻面氧化锰在去除有机污染物、去除空气污染物、去除重金属、能源生产和储存方面的应用。最后，总结了余下的挑战，并提出了未来研究的展望。相信这些将为氧化锰晶体的刻面工程发展提供指导。

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
