Crystal geometry can greatly influence the emergent properties of quantum materials. As an example, kagome lattice is ideal platform to study rich interplay between topology, magnetism, and electronic correlation. In this work, combining high-resolution angle-resolved photoemission spectroscopy ab initio calculation, we systematically investigate structure $X{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ $(X=\mathrm{Dy},\mathrm{Tb},\mathrm{Gd},\mathrm{Y})$ family compounds. We observe Dirac fermion...
Abstract Synthesis of ammonia by electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the Haber–Bosch process. However, it commonly obstructed high activation energy. Here, we report design and synthesis an Al−Al bonded dual atomic catalyst stabilized within amorphous nitrogen‐doped porous carbon matrix (Al 2 NC) with NRR performance. The Al ‐sites act synergistically catalyze complex multiple steps through adsorption activation, enhancing proton‐coupled electron...
A major obstacle of transition metal disulfides in sodium‐ion batteries is compositional irreversible conversion, leading to fast capacity decay. Here, we propose engineer a catalytic superlattice structure for achieving record‐high reversible conversion degree (≈100%). The constructed by alternately stacking MoS2 layers and nitrogen/oxygen co‐doped reduced graphene oxide‐supported single‐atom (MoS2/M‐ONG SL, M=Fe, Co, Ni, Cu, Zn) with 100% MoS2/M‐ONG interfaces, which the atoms bridge two...
Herein, using density functional theory calculations complemented by microkinetic modeling, we systematically investigated hydrodeoxygenation (HDO) of phenol, a model compound for phenolic oxygenates, over two Pt-based bimetallic alloys, namely, M@Pt(111) single-atom surface alloys and M/Pt(111) complete where M = Mo, Fe, Co, Ni. Our results show that is more readily to be formed than in the HDO reaction environment. Benzene formation on Mo@Pt(111) produced almost entirely from partial...
The unique electronic structure of rare-earth elements makes their modified semiconductor photocatalysts show great advantages in solar energy conversion. Herein, the pollen-like N, P self-doped biochar-based composite catalyst (Er/LP-C) has been successfully synthesized, which combines biochar and Er is used for first time field photocatalytic hydrogen production from ethanol-water mixtures. Experimental results confirmed that performance under full spectrum up to 33.70 μmol/g 6 h; this due...
The mechanistic understanding of hydrogenolysis asymmetric Caryl–O–Calkyl bonds is key to the rational design high-performance catalysts for bio-oil upgrading. Herein, we theoretically explore hydrodeoxygenation (HDO) anisole, a prototypical model compound lignin-derived bio-oils, over homogeneous NiFe(111)- and PtFe(111)-alloyed surfaces within framework density functional theory. Our results demonstrate that hydrogenation (HY)/dehydrogenation serves as molecular mediator...
Porous biochar materials prepared with biomass as a precursor have received widespread attention. In this work, lotus pollen (LP) was used the carbon source, variety of photocatalyst were by two-step roasting method. A series characterizations carried out on samples, and it found that average particle size about 40 μm. They also exhibit typical amorphous structure porous network-like interconnected surface. The photocatalytic hydrogen production performances (LP-C) commercial black (CB)...
Underpotential electrochemical deposition is a convenient approach for precisely controlling the fabrication process of single-atom catalysts (SACs). In achieving balance between raising loading SACs and suppressing aggregation adsorbates, working electrode potential should be deliberately optimized, which adsorption isotherm atomically dispersed adsorbates versus electric crucial importance in performance tuning. We report an integrated theoretical scheme simulating isotherm, can enormously...
Designing effective Pt-free catalysts and understanding their mechanism of the electrochemical ammonia oxidation reaction (AOR) are critical for hydrogen production. In this study, we theoretically investigated AOR underlying N2 formation over β-NiOOH(0001) β-M@NiOOH(0001) (M = Fe, Co, Cu) surfaces to explore roles doping strain on AOR. The enhancement in catalyst activity observed with effect was essentially attributed upshifted εd, which strengthened key intermediate Eads(NH2). enabled...
