Abstract The carbon dioxide (CO 2 ) cycloaddition of epoxides to cyclic carbonates is great industrial importance owing the high economical values its products. Single‐atom catalysts (SACs) have potential in CO by virtue their atom utilization efficiency and desired activity, but they generally suffer from poor reaction stability catalytic activity arising weak interaction between active centers supports. In this work, Ir single atoms stably anchored on WO 3 support (Ir 1 –WO are developed...
Li–O2 batteries (LOBs) are considered as one of the most promising energy storage devices due to their ultrahigh theoretical density, yet they face critical issues sluggish cathode redox kinetics during discharge and charge processes. Here we report a direct synthetic strategy fabricate single-atom alloy catalyst in which Pt is precisely dispersed ultrathin Pd hexagonal nanoplates (Pt1Pd). The LOB with Pt1Pd demonstrates an ultralow overpotential 0.69 V at 0.5 A g–1 negligible activity loss...
Revealing the catalytic oxidation mechanism of volatile organic compounds (VOCs) is insightful for development efficient catalysts. However, because complicated interactions and a large number intermediate species during reactions, analysis entire reaction (including activation modes reactant molecules rate-limiting step) remains great challenge. Herein, YMn2O5 mullite catalyst was proposed to demonstrate how distinguish deep difference among C3–C4 alkanes olefins via combining experiments...
Abstract Electrochemical reduction of nitrate to ammonia (NH 3 ) not only offers a promising strategy for green NH synthesis, but also addresses the environmental issues and balances perturbed nitrogen cycle. However, current electrocatalytic processes are still inefficient due lack effective electrocatalysts.

The traditional method for synthesizing NH 3 is the Haber–Bosch process which results in high‐fuel consumption and environmental pollution. Therefore, ecofriendly electrochemical synthesis of through nitrate (NO − ) reduction a good choice. Herein, an integral Au/Cu electrode to catalyze NO introduced. catalyst exhibits not only highest yield rate (73.4 mg h −1 cm −2 up now but also very high Faradaic efficiency 98.02% at −0.7 V room temperature. It commonly believed that transformation...
Abstract The practical applications of zinc metal anode are restricted by detrimental dendrite growth and hydrogen evolution reaction (HER), especially at high current densities. Previous works have demonstrated that constructing Zn(002) texture could effectively suppress HER. However, the surface grain distribution commercial remains indistinct. Herein, a simple mechanical grinding approach is to construct (002)‐textured anodes. After grinding, (002) relative coefficient increases from...
The Mn-Mn dimer has been found to be catalytically active in various manganese oxides for NO oxidation. However, date, it remains unclear how the determines catalytic performance. Herein, we employed a combination of DFT theoretical calculations and an experimental approach investigate O2 dissociation capability oxidation activity single Mn sites with varying bond lengths. Our results indicate that outperform both activation This enhancement is primarily attributed short-range ordered...

Manganese oxides with versatile valence display an enormous potential in lithium-ion battery (LIB) anode materials, but deficient lithium storage capacity, short discharge platform, and inferior cycle stability at high current density greatly hinder their application. Herein, MnO/Mn2O3 nanowires coated by porous N-doped carbon (MnO/Mn2O3–NC) layers are fabricated via wrapping ZIF-8 on MnO2 combined annealing postprocessing. In the LIB test, this material exhibits superior initial specific...
