Abstract Technologies for electrochemical energy conversion play a pivotal role in mitigating global warming and facilitating the transition to a sustainable energy society. Metallophthalocyanine‐based electrocatalysts offer significant advantages due to their coordination flexibility, tunability, and electron‐deficient nature, all of which enhance electron transfer. Herein, we present a systematically designed electrocatalyst library comprising eight metallophthalocyanines, each tailored to address five key energy conversion reactions. By integrating theoretical modeling with experimental approaches, we conduct an in‐depth analysis of the electronic configurations and atomic symmetries of the catalysts. Our study elucidates not only the intrinsic catalytic efficiency but also the scalable synthesis and practical deployability of these electrocatalysts, thereby substantiating their potential for real‐world applications. Overall, we aim to accelerate the energy transition, reduce environmental impact, and enhance economic competitiveness by establishing a robust electrocatalyst library for a carbon circular economy. image
