2024年10月1日 · By integrating carbon-based reduced graphene oxide (rGO) into oxygen-deficient NiS, the poor conductivity of the material may be enhanced. This improvement is shown by the low Rct (0.07 Ω) value measured via electrochemical impedance spectroscopy (EIS).

2021年6月1日 · Owing to these advantages, the ZnCoMnO 4 /N-rGO catalyst shows superior OER and ORR catalytic performance. When assembled into a Zn-air battery, ZnCoMnO 4 /N-rGO exhibits a lower discharge/charge overpotential and a higher catalytic durability than commercial Pt/C, thus further highlighting the advantages of the strongly coupled structure.

2024年10月28日 · In this work, we have focused on the preparation of copper hexacyanoferrate/boron doped rGO composites (abbreviated as CuHCF/B-rGO) by employing simple co-precipitation technique subsequently...

2019年10月3日 · The excellent OER performance as well as good stability of the FeNiS 2 NS/rGO hybrids were attributed to the support of rGO scaffolds. The rGO scaffolds facilitate a rapid electron transport between the domains, and enable the good dispersibility of the FeNiS 2 NS to expose a large number of active sites.

2024年8月1日 · Highly productive catalysts are necessary in oxygen evolution reaction (OER) to lower overpotential and enhance sluggish kinetics of the reaction. In this work, we present an effective OER electrocatalyst, i.e. composite of FeSe with reduced graphene oxide (FeSe/rGO) fabricated via hydrothermal method.

2024年6月21日 · In this work, bimetallic Co/Mo oxides modified reduced graphene oxide (rGO) was synthesized using a simple one-pot hydrothermal method, which significantly improved the electrocatalytic activity in both HER and OER. Under the optimal conditions, the double layer capacitance of rGO modified by Co/Mo bimetal is 78.08 mF cm−2.

2023年10月17日 · The composite structure with rGO support and small particle size of IrO2 allow homogeneous dispersion, and large adsorption area, which dramatically enhances the electron and proton transports. The increased electrochemical surface area resulted in excellent performance of OER.

2023年9月26日 · Herein, we report a dual-laser pulse-patterned heterointerface of α-Co (OH) 2 and reduced graphene oxide (rGO) nanosheets via pulsed laser irradiation in liquid (PLIL) to accelerate OER kinetics. α-Co (OH) 2 was formed from the OH − ions generated during the PLIL of GO at neutral pH.

2024年7月22日 · The higher OER activity of NbSe 2 /rGO is due to incorporation of rGO which gives more active pores and a high number of electrons for OER. All these results verified that fabricated NbSe 2 /rGO nanocomposite is an effective electrocatalyst for the OER.

2024年9月26日 · Therefore, this work proposes a strategic electrochemical synthesis of a reduced graphene oxide and cobalt–nickel hexacyanoferrate (rGO/CoNiHCF)-derived composite (rGO/CoNiPBd-OOH) to achieve optimized OER performance. The optimum rGO/CoNiHCF was fabricated with the Co:Ni precursors in a 3:1 ratio with a ferricyanide solution of pH = 1.0.
