论文摘要
多年来，金属纳米颗粒可以通过不同的机制在黑暗和照明下催化各种化学反应。在过去的十年左右的时间里，已经提出了许多关于等离子辅助“热”电子驱动键盘反应催化的主张。在最近的一系列论文中，这些主张是\ xyz {挑战}，其中详细研究了“热”电子产生的基本理论和使用特定的实验设置在化学反应中发现它们。从这些作品中产生的结论是，只要系统内部存在温度梯度（与典型的实验设置），对非热效应的量化接近不可能。取而代之的是，标准的热理论被证明能够非常准确地解释实验发现。在这里，我们从个人角度回顾了导致这些结论的中心思路。我们列出了该理论的关键方面，并指出了执行光学催化实验时必须注意的特定警告。最后，我们提供了一些未来的研究方向。
It has been known for many years that metallic nanoparticles can catalyse various chemical reactions, both in the dark and under illumination, through different mechanisms. In the last decade or so, many claims of plasmon-assisted "hot" electron driven catalysis of bond-dissociation reactions have been put forward. These claims were \XYZ{challenged} in a recent series of papers, where both the underlying theory of "hot" electron generation and the use of specific experimental setups to discover them in chemical reactions were examined in detail. The conclusion that arose from these works is that as long as temperature gradients exist inside the system (as for typical experimental setups) a quantification of non-thermal effects is close to impossible. Instead, a standard thermal theory was shown to be capable of explaining the experimental findings quite accurately. Here, we review the central lines of thought that led to these conclusions, from a personal perspective. We lay out the key aspects of the theory, and point to the specific caveats one must be aware of in performing photo-catalysis experiments. Finally, we provide some future directions of study.
