Abstract The coordination microenvironment of metal active sites in metal–organic frameworks (MOFs) plays a crucial role its performance for electrochemical CO 2 reduction reaction (CO RR). However, it remains challenge to clarify the structure–performance relationship RR catalyzed by MOFs. Herein, series MOFs with different microenvironments Cu(I) (CuCl, CuBr, and CuI) evaluate their performances is synthesized. With increasing radius halogen atom, adsorption capacity increases d‐band...
As a sustainable and environmentally friendly route, electrochemical N2 reduction has been expected to replace the traditional fixation process of Haber–Bosch, which is energy-consuming capital-intensive. In this work, we demonstrate that CeO2 nanorod with oxygen vacancies achieves great enhancement for NRR excellent selectivity stability. Such electrocatalyst delivers NH3 yield 16.4 μg h–1 mg–1cat. at −0.5 V vs reversible hydrogen electrode (RHE) Faradaic efficiency 3.7% −0.4 RHE using...

It is of great importance to search for efficient and stable metal-free catalysts toward electrochemical N2-to-NH3 conversion. In this communication, a chemically oxidized carbon nanotube material (O-CNT) verified as an active electrocatalyst the N2 reduction reaction under ambient conditions. 0.1 M LiClO4, O-CNT achieves large NH3 yield 32.33 μg h-1 mgcat.-1 high faradaic efficiency 12.50% at -0.4 V vs. reversible hydrogen electrode. also demonstrates superior stability. Density functional...
The search for high-temperature superconductivity is one of the research frontiers in physics. In sulfur hydride system, an extremely high Tc (∼200 K) has been recently developed at pressure. However, Meissner effect measurement above megabar pressures still a great challenge. Here, we report identification pressure, employing situ alternating-current magnetic susceptibility technique. We determine superconducting phase diagram, finding that suddenly appears 117 GPa and reaches 183 K 149...
Electrochemical reduction of NO to NH3 is great significance for mitigating the accumulation nitrogen oxides and producing valuable NH3. Here, we demonstrate that CoS nanosheet with sulfur vacancies (CoS1-x) behaves as an efficient catalyst toward electrochemical NO-to-NH3 conversion. In 0.2 M Na2SO4 electrolyte, such CoS1-x displays a large yield rate (44.67 μmol cm-2 h-1) high Faradaic efficiency (53.62%) at -0.4 V versus reversible hydrogen electrode, outperforming counterpart (27.02 h-1;...
Synthesis of green ammonia (NH3 ) via electrolysis nitric oxide (NO) is extraordinarily sustainable, but multielectron/proton-involved hydrogenation steps as well low concentrations NO can lead to poor activities and selectivities electrocatalysts. Herein, it reported that oxygen-defective TiO2 nanoarray supported on Ti plate (TiO2-x /TP) behaves an efficient catalyst for reduction NH3 . In 0.2 m phosphate-buffered electrolyte, such TiO2-x /TP shows competitive electrocatalytic synthesis...
To develop a new practical method of purifying and recycling ionic liquids, we performed direct microscopic observations in situ crystallization low-melting liquid, 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF(6)]), detail by high pressure Raman spectroscopy. Compression [BMIM][PF(6)] was measured under pressures up to about 2.0 GPa at temperatures 293-353 K using diamond anvil cell (DAC). At room temperature, with increasing, the characteristic bands displayed nonmonotonic...
