A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Synthesis of Single‐Crystalline Ni‐Rich Cathodes for Lithium‐Ion Batteries With Superior High‐Voltage Stability by Mo/Nb Dual Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel synthesis method of single‐crystalline LiNi0.8Co0.15Al0.05O2 (NCA) is introduced, involving the stripping of grain boundaries from polycrystalline NCA (PC‐NCA) during Mo/Nb co‐doping. Mo doping near the grain surface significantly reduces parasitic interface reactions and inhibits the excessive growth of CEI films, while Nb doping within the ...

Developing a Suitable Anion Exchange Layer Structure for Pure–Water Fed Bipolar Membrane CO2 Electrolysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A porous anion exchange layer (AEL) is implemented in a forward‐biased bipolar membrane CO2 electrolyzer to suppress carbonate crossover, support CO2 regeneration and maintain cathode alkalinity. Two fabrication strategies are compared—deposition on a silver gas diffusion electrode (GDE) or on the CEM—showing that a porous AEL‐coated GDE provides the ...
