Abstract

Laser ablation in liquids (LAL) has attracted widespread attention over the last decade and has gradually become an irreplaceable technique for synthesizing nanocrystals and fabricating functional nanostructures because LAL can offer effective solutions to some challenging issues in the field of nanotechnology. In the last few years, we have witnessed exciting developments in the understanding of LAL and its application for fabricating unique nanostructures, especially in the application of LAL-generated nanomaterials to biomedicine, the environment, and energy production. Following the development of LAL, we very recently developed a simple, clean, and efficient LAL-based technique, laser bubbling in liquids (LBL), to produce clean energy through hydrogen production, carbon dioxide reduction, ammonia synthesis, etc. A series of chemical reactions occur inside micro- and nanobubbles under the extreme thermodynamic state induced by a laser at normal temperature and pressure upon LBL. Compared with traditional catalytic chemical reactions, the chemical reactions that occur in the LBL process have the following characteristics. Thermodynamically, the far-from thermodynamic equilibrium state with a high temperature inside micro- and nanobubbles created by LBL provides microenvironments for chemical reactions that typically require catalyst assistance in the absence of a catalyst. In terms of kinetics, the rapid quenching of micro- and nanobubbles confined by the liquid enables accurate control of the chemical reaction and reduces the generation of byproducts. Laser production of clean energy via LBL can be expected to be a simple, green, and efficient technique on an industrial scale under normal conditions beyond chemical catalysis. This review surveys the discovery and application of LBL and provides a comprehensive understanding of laser production of clean energy and a perspective for the further development of LBL.
超越化学催化:激光生产清洁能源。
近十年来,液体激光烧蚀技术受到了广泛的关注,并逐渐成为合成纳米晶体和制造功能纳米结构的不可替代的技术,因为液体激光烧蚀技术可以有效地解决纳米技术领域的一些难题。在过去的几年中,我们见证了对LAL的理解及其在制造独特纳米结构方面的应用的令人兴奋的发展,特别是在LAL生成的纳米材料在生物医学,环境和能源生产方面的应用。随着LAL的发展,我们最近开发了一种简单、清洁、高效的基于LAL的技术——液体激光鼓泡(LBL),通过制氢、二氧化碳还原、氨合成等生产清洁能源。在常温常压激光照射下,在极端热力学状态下,微泡和纳米泡内部发生了一系列化学反应。与传统的催化化学反应相比,LBL过程中发生的化学反应具有以下特点。从热力学角度来看,LBL产生的微气泡和纳米气泡内部的高温远非热力学平衡状态,为在没有催化剂的情况下通常需要催化剂辅助的化学反应提供了微环境。在动力学方面,液体限制的微气泡和纳米气泡的快速淬火可以精确控制化学反应并减少副产物的产生。在常规条件下,LBL激光生产清洁能源是一种超越化学催化的简单、绿色、高效的工业规模技术。本文综述了LBL的发现和应用,对清洁能源的激光生产提供了一个全面的认识,并对LBL的进一步发展进行了展望。
