65Bridging Laboratory Electrocatalysts with Industrially Relevant Alkaline Water Electrolyzers
Advanced Energy Materials, Год журнала: 2024, Номер 14(16)
Опубликована: Фев. 14, 2024
Abstract The alkaline water electrolyzer (AWE) is the earliest and most mature water‐splitting technology. However, conventional Raney Ni electrocatalysts dominantly used in AWEs are struggling to meet current demands for higher energy efficiency cost‐effectiveness green hydrogen production. Although many promising electrocatalytic materials have been developed using facile preparation methods laboratory, they not received much attention commercial AWE applications. It due academic negligence on specific operational conditions, critical performance metrics, material costs associated with industrial AWEs, as well disregarding impact of large‐scale electrode manufacturing processes catalytic performance. Therefore, a timely review bridge laboratory focus requirements essential guide future development electrocatalysts. Here, starting from differences operating testing conditions between systems, gaps equipment, evaluation methods, principles electrodes outlined. To narrow these gaps, some efforts advancing industrially relevant highlighted personal perspectives opportunities, research focus, challenges this field provided.

Опубликована: Фев. 4, 2025
ABSTRACT The growing global energy demand and environmental concerns like greenhouse gas emissions call for clean solutions. Hydrogen energy, with high caloric value low impact, is a promising alternative, especially when produced via proton exchange membrane water electrolysis (PEMWE). This process relies on the hydrogen evolution reaction (HER) oxygen (OER), both requiring efficient electrocatalysts. Platinum (Pt), most effective HER catalyst, limited by cost scarcity, prompting research into Pt alternatives ruthenium‐based, transition metal derivatives, metal‐free catalysts that balance cost, efficiency, stability. review explores mechanisms, Pt‐free catalyst innovations, impact of structural interfacial electrode optimization performance in acidic media. It also examines electrochemical evaluation techniques, material characterization, role machine learning design. By providing framework development, this supports advancements sustainable technologies.

0Synergistic Teamwork of Non-Noble Metals: The Design of Active and Robust Intermetallic Compounds for Hydrogen Evolution Reaction in Industrial Alkaline Water Electrolysis
Inorganic Chemistry, Год журнала: 2025, Номер unknown
Опубликована: Фев. 10, 2025
In this work, we have demonstrated a double-boosting strategy that can significantly enhance the stability of hydrogen evolution reaction (HER) for non-noble-metal-based electrocatalysts operating in harsh industrial conditions (6.0 M KOH, 343 K). With incorporation early-transition-metal and main-group elements Ni metal, ternary TiAlNi2 TiNi2Sn both exhibit higher robust durability HER than binary AlNi metal due to strong bonding states Ti-Ni Al/Sn-Ni below Fermi level. Additionally, they display remarkable efficiency, which only overpotentials ca. -22 -67 mV are required reach current density 10 mA/cm2 (η10) 1.0 KOH. Theoretical calculation revealed their outstanding activities (outperforming commercial Pt/C, Pt = 5 wt %, η10 -76 mV) be attributed synergistic teamwork among Ti, Ni, Al/Sn elements. The at 500 much smaller foam. More importantly, show steady performances over period 400 h high (400 mA/cm2) conditions.

0Correlation between d Electrons and the Sweet Spot for the Hydrogen Evolution Reaction: Is Platinum Always the Best Electrocatalyst?
Inorganic Chemistry, Год журнала: 2024, Номер 63(11), С. 5076 - 5082

Herein, two Laves intermetallic series, ZrCo1.75M0.25 and NbCo1.75M0.25 (M = Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt), were synthesized, their hydrogen evolution reaction (HER) activities examined to reveal the influence of d electrons corresponding HER activities. Owing different electronegativity between Zr Nb (χZr 1.33; χNb 1.60), Co and/or M elements receive more in than that one. This leads overall weak H adsorption energy (ΔGHad) series compared rationalizes well superior activity Rh member Pt one series. Under industrial conditions (333 K, 6.0 KOH), ZrCo1.75Rh0.25 only requires an overpotential 110 mV reach current density 500 mA/cm2 can be operated at high over 400 h. work demonstrates with a proper combination phases, manipulate active metal closer sweet spot (ΔGHad 0). The may no longer exhibit best all potential outperform careful control electron population.
