Type: article
Abstract: It has been hypothesized that molybdenum disulfide , also known as MoS 2 , is an attractive option for the synthesis of hydrogen with a high degree of efficiency. It is preferred to construct a hybrid based on MoS 2 in order to increase the catalytic efficiency, and it is vital to have a grasp of the nature of catalysis in order to make advances in this sector. In this paper, we use reduced graphene oxide , generally known as rGO, to create a MoS 2 @RGO hybrid catalyst with a number of favorable characteristics for the hydrogen evolution process (HER). The MoS 2 @RGO hybrids are next subjected to a battery of analytical tests, including TGA , XRD , TEM , XPS, Raman and BET. 1T MoS 2 @RGO hybrids demonstrated short Tafel slopes (46 and 52 mV.dec ‑1 ) and low levels of overall (70 and 71 mV versus RHE) in both alkaline and acidic electrolytes, allowing for a high current density of 10 mA.cm 2 . The findings show that HER exists in flawed heterostructures . Because 1T phase molybdenum disulfide (MoS 2 ) has more functional sites and a higher intrinsic permeability , it is responsible for the catalyst's outstanding HER efficiency. This paper presents a novel way for fabricating highly active and responsive HER catalysts, as well as a way that is both feasible and practical for fabricating defective-MoS 2 @RGO heterostructures .
