2021年9月28日 · Herein, we introduce electron-deficient metal on semiconducting metal oxides-consisting of Ir (Rh, Au, Ru)-MoO 3 embedded by graphitic carbon layers (IMO) using an electrospinning method. We...

2023年12月8日 · This work reports a high activity and stability RuO 2 /MoO 3 catalyst for water electrolysis. The catalyst exhibits an oxygen evolution reaction (OER) performance with an overpotential of 267 mV at 10 mA cm –2 and demonstrates outstanding long-term stability.

In this work, it is found that the intrinsic OER activity of α-MoO 3 is remarkably improved by incorporating guest ions of lithium-ion (Li +). α-MoO 3 nanoparticles were deposited on a carbon fiber paper (α-MoO 3 /CFP) by chemical vapor transport and a subsequent lithiation process was applied to prepare lithiated α-MoO 3 /CFP (Li-α-MoO 3 ...

2024年8月6日 · Balancing the trade-off between the activity and durability of acidic oxygen evolution reaction (OER) catalysts is of key concern in the field of electrocatalysis. RuO2 delivers good activity but displays poor stability due to the over-oxidation and consequent leachability of surface ruthenium species. Herei

2023年11月1日 · In this work, the highly dispersed IrO x nanoparticles are fabricated on MoO3 sheets coated Ti meshes (c-IrO x -MoO 3 /Ti) as efficient electrocatalytic electrodes for acidic water oxidation.

2023年11月30日 · Here, a self-supporting heterostructured catalyst (named MoO 3 /NiFe-NF) is synthesized via a hydrothermal method to grow NiFe-LDH with oxygen vacancies (O V) in situ on inexpensive nickel foam (NF). Subsequently, MoO 3 is anchored and grown on the surface of NiFe-LDH by electrodeposition.

In this work, we report the growth of MoO 3 nanowires (NWs) by thermal evaporation with the aim of evaluating their use as catalysts for oxygen evolution reaction (OER) in water splitting application. Growth was performed on two different kinds of substrates, Si (100) and Si (111), and at different growth temperatures between 200 and 400 °C.

Developing high-efficiency and low-cost electrocatalysts for the oxygen evolution reaction (OER) is needed for sustainable fuel production and energy storage. However, the inherent scaling relationship in the conventional adsorbate evolution mechanism (AEM) limits the development of electrocatalysts.

2021年12月5日 · The Fe-S-NiMoO 4 /MoO 3 @NF electrode exhibits a high electrocatalytic OER activity and stability, which almost meets the requirements for industrial OER. This work develops an effective strategy to construct industrial electrocatalysts for large-scale applications.

2023年6月16日 · Developing high-efficiency and low-cost electrocatalysts for the oxygen evolution reaction (OER) is needed for sustainable fuel production and energy storage. However, the inherent scaling relationship in the conventional adsorbate evolution mechanism (AEM) limits the development of electrocatalysts.
