Electrochemical conversion of CO2 into valued products is one the most important issues but remains a great challenge in chemistry. Herein, we report novel synthetic approach involving prolonged thermal pyrolysis hemin and melamine molecules on graphene for fabrication robust efficient single-iron-atom electrocatalyst electrochemical reduction. The single-atom catalyst exhibits high Faradaic efficiency (ca. 97.0 %) CO production at low overpotential 0.35 V, outperforming all Fe-N-C-based...
The ability to tune both local and global environments of a single-metal active center on support is crucial for the development highly robust efficient single-atom electrocatalysts (SAECs) that can surmount thermodynamic kinetic constraints in electrocatalysis. Here, we designed core–shell-structured SAEC (Co1-SAC) with superior oxygen reduction reaction (ORR) performance. Co1-SAC consists locally engineered single Co-N3C1 site N-doped microporous amorphous carbon enveloped by globally...
Abstract Photocatalytic overall water splitting into hydrogen and oxygen is desirable for long-term renewable, sustainable clean fuel production on earth. Metal sulfides are considered as ideal hydrogen-evolved photocatalysts, but their component homogeneity typical sulfur instability cause an inert production, which remains a huge obstacle to water-splitting. Here, distortion-evoked cation-site doping of ZnIn 2 S 4 (D-O-ZIS) creates significant electronegativity differences between adjacent...
Intensive research in electrochemical CO2 reduction reaction has resulted the discovery of numerous high-performance catalysts selective to multi-carbon products, with most these still being purely transition metal based. Herein, we present high and stable products selectivity up 76.6% across a wide potential range 1 V on histidine-functionalised Cu. In-situ Raman density functional theory calculations revealed alternative pathways that involve direct interactions between adsorbed histidine...
Abstract The electrochemical conversion of nitrate to ammonia is a way eliminate pollutant in water. Cu-Co synergistic effect was found produce excellent performance generation. However, few studies have focused on this high-entropy oxides. Here, we report the spin-related nitrate-to-ammonia using oxide Mg 0.2 Co Ni Cu Zn O. In contrast, Li-incorporated MgCoNiCuZnO exhibits inferior performance. By correlating electronic structure, that spin states are crucial for pair with high O can...
Tuning interfacial electric fields provides a powerful means to control electrocatalyst activity. Importantly, can modify adsorbate binding energies based on their polarizability and dipole moment, hence operate independently of scaling relations that fundamentally limit performance. However, implementation such strategy remains challenging because typical methods the field non-uniformly affects only minority active sites. Here we discover uniformly tunable modulation be achieved using model...
Bulk molybdenum disulfide is known to be a nonmagnetic material. We have synthesized edge-oriented MoS2 nanosheet-like films that exhibit weak magnetism (∼1−2 emu/g) and 2.5% magnetoresistance effects with Curie temperature of 685 K. The magnetization related the presence edge spins on prismatic edges nanosheets. Spin-polarized calculations were performed triangular-shaped cluster models in order provide insight into origin as well size-property correlation these Our results imply...

For small Pt nanoparticles (NPs), catalytic activity is, as observed, adversely affected by size in the 1–3 nm range. We elucidate, via first-principles-based thermodynamics, operation H* distribution and cyclic voltammetry (CV) during hydrogen evolution reaction (HER) across electrochemical potential, including underpotential region (U ≤ 0) that is difficult to assess experiment. consider multiple adsorption sites on a 1 NP model show characteristic CV peaks from different species...

Facet-engineered monoclinic WO 3 was investigated to explore the effects on photo-assisted LOB kinetics and discharge mechanism. This work can pave way for rational photocathode design in metal–O 2 batteries.
Remolding the reactivity of metal active sites is critical to facilitate renewable electricity-powered water electrolysis. Doping heteroatoms, such as Se, into a crystal lattice has been considered an effective approach, yet usually suffers from loss functional heteroatoms during harsh electrocatalytic conditions, thus leading gradual inactivation catalysts. Here, we report new heteroatom-containing molecule-enhanced strategy toward sustainable oxygen evolution improvement. An organoselenium...
A small amount of methoxide additive is found to effectively induce preferential adsorption anions ( i.e. , TFSI − and NO 3 ) on the surface Li metal anode, contributing an inorganic-rich SEI enabling stable batteries.

Electrochemical CO2 reduction (CO2 R) in acidic media with Cu-based catalysts tends to suffer from lowered selectivity towards multicarbon products. This could principle be mitigated using tandem catalysis, whereby the *CO coverage on Cu is increased by introducing a CO generating catalyst (e.g. Ag) close proximity. Although this has seen significant success neutral/alkaline media, here we report that such strategy becomes impeded electrolyte. was investigated through co-reduction of 13 /12...
