Anchoring Co3S4 nanowires on NiCo2O4 nanosheet arrays as high-performance electrocatalyst for hydrogen and oxygen evolution

“…From the TEM images, it can be seen that there are two struc- The above results reveal that there is strong electron interaction between Co, Fe, S and O after the formation of the heterostructure at the NiCo 2 O 4 / Co 3 S 4 heterostructure interface, and the potential interfacial electronic structure reconfiguration will be benefit to promote the electrocatalytic activity during water splitting. [46][47][48][49][50][51][52] After understanding the composition and structure of the catalysts, electrocatalytic activity of the catalysts was further analyzed. The HER performance of the catalysts was assessed in KOH (1 M) solution.…”

NiS2-Coated Carbon Fiber Paper Decorated with MoS2 Nanosheets for Hydrogen Evolution

“…Nanostructured catalysts are intensively studied for water splitting for their outstanding HER performance due to the lager specific surface area and abundant active sites. Transition metal disulfides (NiS 2 , CoS 2 , and MoS 2 ) have attracted extensive attention due to their advantages, such as a large specific surface area, great stability, and abundant electroactive sites, thus exhibiting an improved efficiency of the HER. − Moreover, compared with other transition metal materials, the preparation conditions of transition metal sulfides are relatively mild. − Therefore, transition metal sulfides can be used to develop catalyst materials for the HER. However, the electrical conductivity and the catalytic activity of transition metal sulfides still needed to be improved .…”

Robust NiCoP@FeP derived from Prussian blue analog for efficient overall water splitting

“…[8][9][10] However, it is still a challenge for non-noble metal-based bifunctional electrocatalysts to achieve high efficiency and strong stability for HER and OER in the same electrolyte. 11,12 Transition metal-based electrocatalysts, such as nickel, cobalt, or iron compounds, 13 oxides, 14,15 sulfides, 16,17 and phosphates, 18,19 are common low-cost alternatives. Among them, transition metal phosphates exhibit excellent catalytic properties for HER 20 and OER.…”
