Metal-nitrogen intimacy of the nitrogen-doped ruthenium oxide for facilitating electrochemical hydrogen production

Morphology engineering induces the increase of FeP/CoP heterointerface density for efficient alkaline water splitting driven by interfacial dual active sites

“…5d, the C dl and ECSA values of FeP/CoP NMs are as high as 23.8 mF cm À2 and 42.0 cm 2 , which are superior to those of FeP/CoP MOs (18.2 mF cm À2 ; 32.1 cm 2 ) and FeP/CoP MRs (16.2 mF cm À2 ; 28.6 cm 2 ), implying that FeP/CoP NMs expose plentiful interfacial dual active sites due to their unique morphology and rich heterointerfaces. [43][44][45] Given the excellent HER and OER properties of FeP/CoP NMs, the FeP/CoP NM catalyst is set as an anode and a cathode in 1.0 M KOH for overall water splitting. Fig.…”

Enhancing Electrocatalytic CO2-to-CO Conversion by Weakening CO Binding through Nitrogen Integration in the Metallic Fe Catalyst

“…Therefore, we developed a hypothesis that the introduction of N in metallic Fe would weaken CO adsorption of Fe sites by the incorporation of Fe–N interactions. In fact, the incorporation of N has been employed to enhance the electrocatalytic performance of transition-metal catalysts toward HER and oxygen evolution reaction. − As a consequence, the integration of nitrogen to regulate the electronic structure of metallic iron sites is a potential strategy for optimizing the CO 2 RR catalytic performance toward CO generation.…”

Heterogeneity in a metal–organic framework in situ guides engineering Co@CoO heterojunction for electrocatalytic H2 production in tandem with glucose oxidation

“…Overall water splitting is of crucial importance in a clean hydrogen economy with hydrogen evolution reaction (HER) at the cathode and oxygen evolution reaction (OER) at the anode. 1,2 However, OER with a four-electron transfer mechanism suffers intrinsic sluggish kinetic rate and undesirably results in a high electrolysis voltage. In addition, O 2 produced at the anode is less valuable and the crossover with H 2 generated from the cathode might cause a safety hazard during industrial water splitting.…”
