Optimizing Pt-Based Alloy Electrocatalysts for Improved Hydrogen Evolution Performance in Alkaline Electrolytes: A Comprehensive Review

ACS Nano, Journal Year: 2023, Volume and Issue: 17(21), P. 20804 - 20824

Published: Nov. 3, 2023

The splitting of water through electrocatalysis offers a sustainable method for the production hydrogen. In alkaline electrolytes, lack protons forces dissociation to occur before hydrogen evolution reaction (HER). While pure Pt is gold standard electrocatalyst in acidic since 5d orbital nearly fully occupied, when it overlaps with molecular water, generates Pauli repulsion. As result, formation Pt–H* bond an environment difficult, which slows HER and negates benefits using catalyst. To overcome this limitation, can be alloyed transition metals, such as Fe, Co, Ni. This approach has potential not only enhance performance but also increase dispersion decrease its usage, thus overall improving catalyst's cost-effectiveness. excellent adsorption ability metals contributes generation proton-rich local near Pt-based alloy that promotes HER. Significant progress been achieved comprehending mechanism manipulation structure composition electrocatalysts based on alloy. objective review analyze condense latest developments It focuses modified alloys clarifies design principles catalytic catalysts from both experimental theoretical perspective. highlights some difficulties encountered during opportunities increasing performance. Finally, guidance development more efficient provided.

Amorphous Fe–Co oxide as an active and durable bifunctional catalyst for the urea-assisted H₂ evolution reaction in seawater

Chemical Communications, Journal Year: 2023, Volume and Issue: 59(66), P. 9992 - 9995

Published: Jan. 1, 2023

In this study, we prepared amorphous iron-cobalt oxide through the dealloying of trimetallic FeCoAl, showing excellent performance in both urea oxidation and hydrogen evolution reactions (UOR HER) alkaline seawater. The catalyst demonstrated stable UOR HER activity during long-term operations due to abundant active sites oxygen vacancies. required applied potentials 1.52 -0.185 V yield 100 mA cm-2 for HER, respectively. Moreover, when used as cathode anode, electrolyzer a working voltage 1.68 urea-assisted production.
