Fabrication of large-scale two-dimensional metallic nanosheets by accumulative rolling

该项目旨在开发新技术，并深入了解金属从散装到纳米厚度的减薄，从而实现大规模二维（2D）金属纳米片的批量制造。将采用一种新的轧制策略来实现厚度小于5nm、横向尺寸大于1mm的2D金属片，并展示出显著改善的电催化性能。该技术有望成为传统自下而上技术的高产、低成本替代方案，并有望在工业上实现批量制造2D金属纳米片。

This project aims to develop new techniques and insight into the thinning of metals from bulk to nano thicknesses which enables bulk manufacturing of large-scale two-dimensional (2D) metallic nanosheets. A novel rolling strategy will be adopted to achieve 2D metallic sheets with thicknesses less than 5nm and lateral sizes larger than 1mm, as well as demonstrating significantly improved electro-catalytic performance. The proposed technique is expected to be a high-yield, low-cost alternative to traditional bottom-up techniques and is expected to be ready for implementation in industry for bulk manufacturing of 2D metallic nanosheets.
