Abstract:
Today, applying of fossil fuels is considered as a challenge and the use of renewable.Cleanenergy can be as a suitable way for decrease this problem. Energy transport such as hydrogenevaluation reaction (HER) was considered as alternative energy technology in the recent years[۱, ۲]. The hydrogen can be product using water splitting reaction [۳]. Although, the rate of theoxygen evolution process at the water splitting reaction is sluggish [۴]. So, a way for obtain highefficiency at water splitting is applying the electrocatalysts which improve the oxygen evaluationreaction (OER). Therefore, OER contains conversion energy and store energy. The present studyreported that the NiCr-LDH/SWCNT nanocomposite is as a superior active for oxygenevaluation reaction (OER). The NiCr-LDH/SWCNT composite was synthesized using theultrasonic sound waves. Based on the characterization analyses such as X-ray diffraction (XRD)patterns, and field emission scanning electron microscopy (FE-SEM) images, the synthesis ofNiCr-LDH/SWCNT using the ultrasonic method, was confirmed. Next, the NiCr-LDH/SWCNTcomposites were used as an effective nanomaterials for OER at near neutral media. The obtaineddata from the linear sweep voltammetry (LSV) process confirm that NiCr-LDH/SWCNTdecreases the overpotential to about ۷۰ mV in comparison with only NiCr-LDH, and RuO۲. Thehigh activity oxygen generation can be attributed to the presence of NiCr-LDH and SWCNT atprepared nanocomposite
