Facet engineering of MnO2: An important strategy for improving its efficiency
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.
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.
