Electrocatalysis offers a promising strategy to take advantage of the increasingly available and affordable renewable energy for the sustainable production of fuels and chemicals. Attaining this promise requires a molecular level insight of the electrical interface that can be used to tailor the selectivity of electrocatalysts. Addressing this selectivity challenge remains one of the most important areas in modern electrocatalytic research. In this Perspective, we focus on the use of in situ techniques to bridge the gap in the fundamental understanding of electrocatalytic processes. We begin with a brief discussion of traditional electrochemical techniques, ex situ measurements and in silico analysis. Subsequently, we discuss the utility and limitations of in situ methodologies, with a focus on vibrational spectroscopies. We then end by looking ahead toward promising new areas for the application of in situ techniques and improvements to current methods.
电催化提供了一种很有前景的策略，可利用日益可得且价格合理的可再生能源来可持续地生产燃料和化学品。要实现这一前景，需要在分子水平上深入了解电界面，以便能够定制电催化剂的选择性。应对这一选择性挑战仍然是现代电催化研究中最重要的领域之一。在这篇综述文章中，我们重点关注利用原位技术来弥合对电催化过程基本理解方面的差距。我们首先简要讨论传统电化学技术、非原位测量和计算机模拟分析。随后，我们讨论原位方法的实用性和局限性，重点是振动光谱学。最后，我们展望原位技术应用的新的有前景领域以及对现有方法的改进。
