Ru decorated Co nanoparticles supported by N-doped carbon sheet implements Pt-like hydrogen evolution performance in wide pH range

“…The calculation indicated the remarkable electrical conductivity and fast electron transport in Ru-Co heterostructure catalyst, favoring the electrocatalytic HER. Moreover, the surface charge density analysis (Figure S14a Combining DFT and electrochemical test results, we can conclude that Ru/Co@NC exhibits the excellent HER activity in 1.0 M KOH, comparable to the most advanced Ru-based materials reported in literature (Figure 5a) [18,23,[49][50][51][52][53][54][55][56]. Besides activity, stability is also a crucial parameter for electrocatalysts, which can be evaluated through the i-t and accelerated attenuation test (ADT).…”

Three-Dimensional Graphene-Supported CoP-RuP2 with Artificial Heterointerfaces for an Enhanced Universal-pH Hydrogen Evolution Reaction

“…With continuous upgrading of the energy crisis and environmental issues stemming from the utilization of fossil fuels, it is of great urgency to develop clean and renewable energy technologies for the development of society. − Electrocatalytic water splitting including the hydrogen evolution reaction (HER) at the cathode and the oxygen evolution reaction (OER) at the anode has been regarded as one of the potential technologies for high-purity hydrogen production. − However, the sluggish kinetics of the HER or OER is the main obstacle for the widespread application of hydrogen, which has drawn extensive attention to explore efficient electrocatalysts with a lower activation energy. , Up to now, Pt is still considered to be the benchmark catalyst toward the HER. However, its high cost, scarce reserves, and poor durability have greatly limited its large-scale implementation .…”

Nitrogen-doped carbon encapsulating a RuCo heterostructure for enhanced electrocatalytic overall water splitting

“…[1][2][3][4] Hydrogen energy with high gravimetric energy density and non-polluting zero carbon content is considered one of the most promising clean energy sources to solve the energy shortage and greenhouse effect. [5][6][7] Electrochemical water splitting is considered the most promising technology for the large-scale production of hydrogen. [8][9][10] However, developing efficient catalysts to overcome the high overpotentials caused by the slow kinetics of the cathodic hydrogen evolution reaction (HER) and anodic oxygen evolution reaction (OER) remains a great challenge.…”
