Electrocatalysis has emerged as a pivotal field for sustainable energy and environmental solutions, fueling the development of diverse electrocatalysts over the past 2 decades. However, a comprehensive understanding of the intricate dynamical processes governing electrochemical reactions remains elusive and is hampering efficient catalyst design. Surfacesensitive techniques like in situ/operando Raman spectroscopy are indispensable for characterizing these dynamic processes and guiding the development of novel catalysts. This review systematically summarizes recent advances in employing in situ/operando Raman techniques, with a particular emphasis on surface-enhanced Raman spectroscopy (SERS), for probing various electrocatalytic systems. It discusses the development, advantages, and available configurations of these Raman techniques. Moreover, the review underscores the potential of in situ SERS in unraveling the intricate mechanisms of the oxygen evolution reaction (OER) through innovative strategies and methodological advancements. Notably, leveraging SERS for novel OER catalysts, such as single-atom catalysts, metal−organic frameworks, and electrolyte− electrode interfaces, can unveil unexplored reaction pathways, guiding the development of superior catalytic materials. Overcoming challenges and harnessing SERS' capabilities can deepen our mechanistic understanding of the OER, enabling the rational design of efficient and durable electrocatalysts crucial for renewable energy advancement.

The current goals for implementing the hydrogen economy have highlighted a need to further optimize water‐splitting technologies for clean hydrogen production. Proton exchange membrane water electrolysis (PEMWE) is a leading technology, but further optimizations of anode materials including the porous transport layer (PTL) and the adjacent catalyst layer (CL) are required to increase overall cell performance and reduce cost. This literature review describes advances in PTL development and characterization, highlighting early PTL characterization work and most common methods including capillary flow porometry and mercury intrusion porometry, optical imaging, neutron and x‐ray radiography, and x‐ray computed tomography. The article also discusses PTL protective coatings and their characterizations, focusing on platinum group metal (PGM)‐based coatings, alternative non‐PGM‐based coatings, post‐treated PTLs, and investigations into thin PGM‐based coatings. Furthermore, it highlights the integration of the PTL and the adjacent CL along with associated characterization challenges. Lastly, this review discusses future developments in the characterization needed to improve PEMWE's performance and long‐term durability are discussed.
