Magnetic Field‐Assisted Water Splitting: Mechanism, Optimization Strategies, and Future Perspectives

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(26)

Published: Feb. 15, 2024

Abstract Rationally designing of highly efficient electrocatalysts is critical to improving hydrogen production by water electrolysis. However, bottlenecks still require consideration when optimizing the intrinsic performance electrocatalysts. Applying appropriate external fields catalytic systems may effectively overcome such and enhance catalysts. Among various fields, magnetic field has received extensive attention owing its multifunctionality, non‐contact nature, non‐invasiveness, thereby requiring more research development. In this review, recent advances in field‐assisted electrolysis are systematically outlined. Firstly, diverse methods used for pre‐regulating catalysts under including optimized nucleation, induction heating, directed growth, discussed. It then explores effects on electrochemical processes, magnetothermal, magnetohydrodynamic, induced electric impact. Then, influences properties catalysts, as spin polarization reconstruction effects, addressed. Finally, a discussion potential perspectives field‐enhanced splitting, catalyst design, experimental precision, situ characterization, provided guide further research.
