“…This nding demonstrates that the oxidation of Ti 3 C 2 T x that has retained its conductive nature should be moderate. 46 So far, we focus on the impedance spectroscopy technique which provides insights into the characterization of the electrical properties of the materials. [47][48][49] The impedance test of the sample lm was performed in an air atmosphere, as reported by Bobkov et al 48 Fig.…”

Strategies to improve electrocatalytic performance of MoS2-based catalysts for hydrogen evolution reactions

“…156 Many studies have examined the impact of vacancies on the HER performance of MoS 2 . 157–167 Theoretically, the rational design of defects on the basal plane of MoS 2 can enhance the HER performance of MoS 2 because the basal plane of MoS 2 is inert while the edge sites are significantly more active.…”

Robust visible-light photocatalytic H2 evolution on 2D RGO/Cd0.15Zn0.85In2S4–Ni2P hierarchitectures

“…By using Ni 2 P as a cocatalyst, composite ZnIn 2 S 4 /Ni 2 P heterostructures displayed an enhanced H 2 evolution rate of 2.066 mmol h −1 g −1 compared to pure ZnIn 2 S 4 , but it is still far from meeting the criteria for practical application. 28 Our recent study indicated that 29 the HER performance of ZnIn 2 S 4 could be enhanced by Cd-doping to achieve light responsive characteristics. Therefore, 2D hierarchitectures based on Cd-doped ZnIn 2 S 4 coupled with graphene and Ni 2 P are expected to possess excellent performance towards visible-light-driven H 2 production.…”
