硅材料是电子产业、光伏产业的基础材料,是国际高科技竞争的焦点领域之一;同时,我国也是全球硅材料、消费的第一大国,因此,开拓硅材料的创新应用将可能促进我国“双碳”等新型高科技产业的发展。本成果利用纳米硅的表面化学可以原位捕获金属或基团的创新思路,开发了纳米硅的新结构,利用其空间、化学、吸光特性,在国际上率先成功开拓了硅在双碳、能源、电子废弃物升级利用、新型半导体等我国大力发展领域的高效应用。
Silicon materials are the fundamental materials for the electronics and photovoltaic industries and are one of the key areas of international high-tech competition. At the same time, China is the world's largest producer and consumer of silicon materials. Therefore, exploring innovative applications of silicon materials has the potential to promote the development of new high-tech industries such as " carbon peaking and carbon neutrality" in our country. This achievement utilizes the surface chemistry of nanosilicon to capture metals or groups in situ, and develops new structures of nanosilicon. By utilizing its spatial, chemical, and light-absorbing properties, we have taken the lead internationally in successfully exploring efficient applications of silicon in areas such as dual carbon, energy, upcycling of electronic wastes, and new semiconductors, which are vigorously developed in our country.
