“…After preparation the catalyst inks, they should be directly deposited on the working electrodes using different methods like drop casting, impregnation, spray coating, and electrochemical deposition, [33] but drop casting is the most common and facile one. Then, prior to the electrochemical tests, the electrodes should be left to dry under vacuum at 80 °C to allow the polymerization of the binder with the catalysts or at a lower temperature if the catalysts are not stable at high temperatures.…”

Pt‐groups are the state‐of‐the‐art electrocatalysts for various fuel cells. However, their CO‐poising is a critical hitch for large‐scale applications, so the researchers are exerting huge efforts to solve this issue. However, the exponentially increasing attention in this field pressures the researchers to publish their findings quickly, which somewhat leads to unavoidable flawed evaluation parameters to reflect the intrinsic activity of electrocatalysts. The CO oxidation (COOxid) is highly sensitive to various factors. Thus, it is urgent to afford a deeper understanding of the inherent COOxid activity of state‐of‐the‐art electrocatalysts and adopt accurate guidelines for researchers to test, optimize, and compare their electrocatalysts. This review provides exactitude in the evaluation and precise assessment of the key descriptors related to electrocatalysts (i.e., effect of both size, shape, and support) and CO oxidation (i.e., effect of electrolyte, working electrode, and CO surface diffusion). This is besides the fundamental aspects (i.e., COOxid Process, mechanism, measurements, calculations, thermodynamics, and kinetics). Various experimental results from our group and others besides in‐situ analysis were provided to support our deep discussion. Finally, we provide a brief synopsis of the relevant milestones of the up‐to‐date challenges and perspectives.
