Due to the low cost and earth abundance, molybdenum sulfide (MoS2) has been identified as a promising electrocatalyst for HER. However, MoS2 shows poor oxygen evolution activity because of its insufficient binding with the reaction intermediate on the catalytic site. Liu et al. utilized 3d transition metal doping to modify the active site of MoS2. 3d-TMO6@MoS2 (TM = Mn, Fe, and Co) shows better OER catalytic activity than the standard catalyst, IrO2. This catalyst also possesses structural stability. Electrochemical synthesis of H2O2 via 2-electron oxygen reduction is challenging due to the high cost of noble metal-based catalysts such as Au-Pd 89 and Au-Pt-Ni. Nickel oxide possess unsaturated metal centers that facilitate proper *OOH binding for electrochemical synthesis of hydrogen peroxide, whereas amorphous metal oxides possess better catalytic properties due to their coordinately unsaturated open sites. Zhang et al. displayed amorphous nickel oxides coated on carbon nanosheets (NiOx-C). This scalable composite NiOx-C selectively catalyzes 2-electron oxygen reduction (~91%) in 0.1M KOH between 0.15-0.60 V to produce H2O2 due to high NiOx-C-*OOH binding strength.
