摘要

物质与光相互作用而受热是自然界中普遍存在的基本过程。在过去的几十年里,随着纳米技术的兴起,人们发现了各种能够将光转化为热的纳米材料,并对其物理化学性质进行了研究。也许最奇特的是通过表面等离子体对金属纳米晶体进行光热加热。在这里,入射的电磁波触发纳米粒子电子云的振荡。当共振时,吸收系数会大大增加,使更多的能量以热量的形式散失。等离子体现象具有令人难以置信的多种功能,从中世纪彩色玻璃窗的鲜艳色彩到纳米级光的定位和增强。等离子体加热或热等离子体是一种相对较新的技术,主要通过在治疗学和生物技术中的应用而获得普及。通过这个帐户,我们的目标是将焦点放在使用热等离子体来驱动化学合成上,这是一个快速发展的研究领域,具有巨大的潜力。纵观化学合成的悠久传统,化学家们很少偏离典型的烤箱或热板来设定和保持反应容器内的均匀温度。相比之下,使用热等离子体纳米材料可以通过在纳米颗粒表面附近形成陡峭的温度梯度来引入反应加热剖面的非均匀性。此外,光热转换使热激活过程受益于光启动的优势,例如,非接触式激活和空间控制。因此,热等离子体为长期存在的规范提供了一个有吸引力的替代方案。一些早期的研究证明了这种方法的力量,利用局部加热来进行反应,而对周围介质的总体温度变化最小。然而,利用这种潜力是非常具有挑战性的,因为即使环境发生很小的变化,胶体溶液也会聚集。不同的策略被用来克服这一障碍,例如将颗粒嵌入玻璃或其他异质基板。我们的团队已经试验了用二氧化硅外壳涂覆金纳米结构。这确保了结构和胶体稳定性,这对热等离子体化学至关重要。近年来,我们将该方法应用于烯烃复分解、氧化铁(IO)、钯(Pd)和银(Ag)纳米颗粒的合成以及各种金属有机框架(mof)的形成。此外,高度稳定的杂化材料可以分离为等离子体粒子与聚合物、mof和其他纳米结构的复合材料。各种各样的反应条件和不同的前驱体、添加剂和催化剂,我们的方法证明是兼容的,突出了二氧化硅封装提供的多功能性。等离子体加热的独特性质加上增加的稳定性,可以为更有效的反应和全新的反应活性以及新型复合材料的形成提供广泛的机会。

Let There Be Heat: Silica-Coated Gold Nanoparticles as Photothermal Reactors for Chemical Synthesis.

ConspectusThe heating of matter upon interacting with light is a fundamental process ubiquitous in the natural world. With the rise of nanotechnology over the past decades, a variety of nanomaterials capable of converting light into heat have been discovered and their physicochemical properties investigated. Perhaps the most exotic is the photothermal heating of metallic nanocrystals via surface plasmons. Here an incoming electromagnetic wave triggers the oscillation of the nanoparticle's electron cloud. When in resonance, this generates an enormous increase to the absorption coefficient, enabling more energy to dissipate as heat. The plasmonic phenomenon has an incredibly diverse range of functions, from the vibrant coloration of medieval stained-glass windows to the localization and enhancement of light at the nanoscale level. Plasmonic heating or thermoplasmonics is a relatively new addition that has gained popularity mainly through applications in therapeutics and biotechnology. With this Account, we aim to put a spotlight on the use of thermoplasmonics to drive chemical synthesis, a rapidly expanding area of research with immense potential.Throughout the long tradition of chemical synthesis, chemists have rarely deviated from the typical oven or hot plate to set and maintain a homogeneous temperature within the reaction vessel. In contrast, the use of thermoplasmonic nanomaterials can introduce heterogeneity to the heating profile of a reaction by forming steep temperature gradients near the surface of nanoparticles. Additionally, photothermal conversion enables heat activated processes to benefit from the advantages of light initiation, e.g., contactless activation and spatial control. Thus, thermoplasmonics offers an attractive alternative to the long-standing norm.Several early studies demonstrated the power of this method, taking advantage of the localized heating to carry out reactions with minimal change to the bulk temperature of the surrounding medium. However, tapping into this potential can be very challenging as colloidal solutions tend to aggregate even with small changes to the environment. Different strategies have been utilized to overcome this obstacle, for example embedding particles into glass or other heterogeneous substrates. Our group has experimented with coating gold nanostructures with a silica shell. This ensures the structural and colloidal stability that is critical for thermoplasmonic chemistry.

The large variety of reaction conditions and the different precursors, additives, and catalysts that our method proved to be compatible with highlight the versatility that silica encapsulation provides.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
