Despite the common belief that manganese (hydr)oxides in absence of other metal ions require high overpotential to catalyze oxygen-evolution reaction (OER) alkaline conditions, our study has uncovered surprising results. Layered oxide demonstrates noteworthy OER activity at Mn(III) Mn(IV) oxidation peak following charge accumulation. This is achieved with remarkably low (120 mV) a 1.0 M KOH solution. Initially, Faraday efficiency modest 20%, which can be attributed initial storage. However, as continues (200 s), significantly increases over 80%. We also propose detailed mechanism for this low-overpotential regime, supported by situ visible and Raman spectroscopies surrounding region. By examining amount oxygen generated concentrations redox-active Mn near redox peak, turnover frequency 3.8 × 10–3 s–1 1.35 V was calculated. The reduced observed during complex interplay between process accumulation it nature, these factors collectively enabling notably overpotential. These findings provide significant insights design development highly efficient stable electrocatalysts water-splitting applications, potentially revolutionizing approaches energy conversion Our have implications applications.

Self-Supported Porous Carbon Monoliths for Electrocatalytic Hydrogen Evolution in Alkaline Freshwater and Seawater

Langmuir, Год журнала: 2024, Номер unknown

Опубликована: Дек. 3, 2024

Developing efficient catalysts for seawater electrolysis hydrogen evolution reaction (HER) is crucial producing green hydrogen. Carbonized wood (CW), a porous carbon monolith, promising self-supporting electrocatalytic electrode owing to its environmentally friendly, sustainable, and hierarchically properties. However, the impact of different tree species on performance remains unclear. In this study, various types CWs, including carbonized poplar (PoCW), balsa (BaCW), fir (FiCW), pine (PiCW), have been selected investigate their in evolution. Among these, PoCW exhibits superior HER compared other attributed electrochemically active surface area, resistance, content oxygen-containing functional groups. demonstrates low overpotential 284 mV 356 at 10 mA cm–2 alkaline freshwater seawater, respectively. Moreover, shows long-term durability 100 h both seawater. This work guides selection wood-based monoliths that metal-free, CW-based electrodes hold great potential
