Abstract 2D MoS 2 is acknowledged as a potential alternative to Pt‐based catalysts for hydrogen evolution reaction (HER) due its suitable * H adsorption energy. However, the weak water capacity of in an alkaline solution limits performance improvement toward HER. Herein, novel rare‐earth Tm single atoms decorated (Tm SAs‐MoS ) catalyst proposed, and key role SAs on enhanced HER identified. It verified that Tm‐site contributes asymmetric [Mo‐S‐Tm] unit site, which serves electron donor disturb electronic state accelerate accumulation at surrounding Mo‐S site. The obtained exhibits significantly improved activity with low overpotential 80 mV 10 mA cm −2 , robust stability good selectivity compared pure most ‐based catalysts. In situ Raman theoretical calculations prove oxophilic sites improves migration thermodynamic spontaneous dissociation interfacial O molecules during by Tm‐4f‐OH orbital overlap. Such [Tm‐S‐Mo] site allows optimal G *H location turn reaches apex volcano plot. This work expected open up new avenues design provide valuable understanding rare earth mechanisms.

Importing Atomic Rare‐Earth Sites to Activate Lattice Oxygen of Spinel Oxides for Electrocatalytic Oxygen Evolution

Angewandte Chemie International Edition, Год журнала: 2024, Номер unknown

Опубликована: Окт. 9, 2024

Abstract Spinel oxides have emerged as highly active catalysts for the oxygen evolution reaction (OER). Owing to covalency competition, OER process on spinel often follows an arduous adsorbate mechanism (AEM) pathway. Herein, we propose a novel rare‐earth sites substitution strategy tune lattice redox of and bypass AEM scaling relationship limitation. Taking NiCo 2 O 4 model, incorporation Ce into octahedral site induces formation Ce−O−M (M=Ni, Co) bridge, which triggers charge redistribution within . The developed Ce−NiCo exhibits remarkable activity with low overpotential, satisfactory electrochemical stability, good practicability in anion‐exchange membrane water electrolyzer. Theoretical analyses reveal that surface more favorable (LOM) pathway non‐concerted proton‐electron transfers compared pure , also verified by pH‐dependent behavior situ Raman analysis. 18 O‐labeled mass spectrometry provides direct evidence released during originates from We discover electron delocalization f states through favoring antibonding state occupation Ni−O bonding [Ce−O−Ni] unit site, thereby activating OER. This work new perspective designing offers significant insights rare‐earth‐enhanced LOM mechanism.

The nitrogen cycle is the biogeochemical by which converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems, conversion of can be carried out through both biological physical processes. Important processes in include fixation, ammonification, nitrification, denitrification. majority Earth's atmosphere (78%) atmospheric nitrogen, making largest source nitrogen. However, has limited availability for use, leading to a scarcity usable many types ecosystems. particular interest ecologists because affect rate key ecosystem processes, including primary production decomposition. Human activities such fossil fuel combustion, use artificial fertilizers, release wastewater have dramatically altered global cycle. modification negatively natural environment system also human health. Volatilization its Relationship N2 fascination Nitrogen Cycle agriculture field discuss this paper.
