  abstract = {<p><span>Significant advances have been made in recent years discovering new electrocatalysts and developing a fundamental understanding of electrochemical CO</span><span>2</span><span>&nbsp;reduction processes. This field has progressed to the point that efforts can now focus on translating this knowledge toward the development of practical CO</span><span>2</span><span>&nbsp;electrolyzers, which have the potential to replace conventional petrochemical processes as a sustainable route to produce fuels and chemicals. In this Perspective, we take a critical look at the progress in incorporating electrochemical CO</span><span>2</span><span>&nbsp;reduction catalysts into practical device architectures that operate using vapor-phase CO</span><span>2</span><span>&nbsp;reactants, thereby overcoming intrinsic limitations of aqueous-based systems. Performance comparison is made between state-of-the-art CO</span><span>2</span><span>&nbsp;electrolyzers and commercial H</span><span>2</span><span>O electrolyzers—a well-established technology that provides realistic performance targets. Beyond just higher rates, vapor-fed reactors represent new paradigms for unprecedented control of local reaction conditions, and we provide a perspective on the challenges and opportunities for generating fundamental knowledge and achieving technological progress toward the development of practical CO</span><span>2</span><span>&nbsp;electrolyzers.</span></p>},
