About this collection

Guest Edited by Associate Professor Wee-Jun Ong (Xiamen University, Malaysia), Professor Markus Antonietti (Max Planck Institute of Colloids and Interfaces, Germany) and Professor Nanfeng Zheng (Xiamen University, China).

Energy has been witnessing a surge of interest over the past few years across the breadth of nanoscience and nanotechnology. Of particular interest, downsizing functional materials to the nanoscale can manifest intrinsically different properties and energy performances compared to their bulky structures. This collection focuses on the use of advanced strategies such as rational size/facet control, structural/defect engineering, atomic modification, and construction of nanohybrids that can regulate the geometric and/or electronic property of the active sites. As such, this gives rise to a substantial improvement in the performance of nanomaterials toward energy conversion and storage.
