Abstract
Zero-emission eco-friendly vehicles with partly or fully electric powertrains have exhibited rapidly increased demand for reducing the emissions of air pollutants and improving the energy efficiency. Advanced catalytic and energy materials are essential as the significant portions in the key technologies of eco-friendly vehicles, such as the exhaust emission control system, power lithium ion battery and hydrogen fuel cell. Precise synthesis and surface modification of the functional materials and electrodes are required to satisfy the efficient surface and interface catalysis, as well as rapid electron/ion transport. Atomic layer deposition (ALD), an atomic and close-to-atomic scale manufacturing method, shows unique characteristics of precise thickness control, uniformity and conformality for film deposition, which has emerged as an important technique to design and engineer advanced catalytic and energy materials. This review has summarized recent process of ALD on the controllable preparation and modification of metal and oxide catalysts, as well as lithium ion battery and fuel cell electrodes. The enhanced catalytic and electrochemical performances are discussed with the unique nanostructures prepared by ALD. Recent works on ALD reactors for mass production are highlighted. The challenges involved in the research and development of ALD on the future practical applications are presented, including precursor and deposition process investigation, practical device performance evaluation, large-scale and efficient production, etc.
期刊介绍:
The International Journal of Extreme Manufacturing (IJEM) focuses on publishing original articles and reviews related to the science and technology of manufacturing functional devices and systems with extreme dimensions and/or extreme functionalities. The journal covers a wide range of topics, from fundamental science to cutting-edge technologies that push the boundaries of currently known theories, methods, scales, environments, and performance. Extreme manufacturing encompasses various aspects such as manufacturing with extremely high energy density, ultrahigh precision, extremely small spatial and temporal scales, extremely intensive fields, and giant systems with extreme complexity and several factors. It encompasses multiple disciplines, including machinery, materials, optics, physics, chemistry, mechanics, and mathematics. The journal is interested in theories, processes, metrology, characterization, equipment, conditions, and system integration in extreme manufacturing. Additionally, it covers materials, structures, and devices with extreme functionalities.
