Comprehensive Guidelines for Magnetoelectrocatalysis: Quantum-Engineered Materials, Mechanistic Insights, and Application Spectrum

Amid the alarming threat of pollution, the electrocatalytic pathway stands out as a frontrunner, offering a promising strategy for clean energy conversion and environmental remediation. However, despite its immense potential, the practical substitution of the industrial process remains an elusive target. Despite conducting considerable research for over a century, the primary problem remains the engineering of an efficient and durable electrocatalyst to overcome bottlenecks and convert electrochemical pathways into viable, scalable technologies. Herein, this work transcends a comprehensive review by bridging material breakthroughs with their fundamental mechanistic insights and, through a meticulous analysis of existing experimental studies, reveals how either a small magnetic field or a fictitious magnetic field orchestrates complex catalytic pathways, positioning itself as a cornerstone work to propel the future of magneto-electrochemistry. The material aspects cover not only the already tested materials but also draw a new roadmap for advanced quantum materials that can change the landscape of spin-based catalysis research. Ultimately, the integration of complex materials with dynamic mechanistic understanding, rational cell engineering across diverse applications, and AI- and ML-driven predictive design is poised to revolutionize magnetic-field-assisted catalysis. This unified and adaptive framework for magneto-electrocatalysis not only delineates existing challenges but also illuminates sustainable and scalable pathways toward next-generation energy conversion, environmental remediation, and green chemical manufacturing.
