Abstract The introduction of oxygen vacancies (Ov) has been regarded as an effective method to enhance the catalytic performance photoanodes in evolution reaction (OER). However, their stability under highly oxidizing environment is questionable but was rarely studied. Herein, NiFe‐metal–organic framework (NiFe‐MOFs) conformally coated on oxygen‐vacancy‐rich BiVO 4 (Ov‐BiVO ) protective layer and cocatalyst, forming a core–shell structure with caffeic acid bridging agent. as‐synthesized...
Ammonia with a hydrogen content of 17.6 wt % is viewed as promising carrier because the infrastructures for its production, storage, and transportation have been well established. The challenge that currently straight production H2 from NH3 only works at high temperatures. To date, various metal-based catalysts developed decomposition, among which Ru-based ones are most superior due to suitable Ru–N binding energy. In past decade, efforts put in improve performance catalysts, target lower Ru...
Abstract Deep eutectic solvents (DESs) are a class of promising media for gas separation. In order to examine the potential application DESs natural upgrading, solubilities H 2 S, CO , and CH 4 in choline chloride (ChCl) plus urea mixtures were measured this work. The solubility data correlated with Henry's law equation calculate thermodynamic properties absorption processes, such as constants enthalpy changes. Grand‐canonical Monte Carlo simulations quantum chemistry calculations also...
Ammonia is an important chemical for synthesized fertilizers traditionally and a potential energy vector increasingly. Industrial ammonia synthesis through the Haber–Bosch process energy-intensive requires advanced materials to catalyze under mild conditions, whereas utilization of as hydrogen carrier via decomposition facing similar situation well. The developed second-generation Ru-based catalysts performs superior activities over commercial Fe- or Ni-based catalysts; however, it remains...
Cu-based bimetallic catalysts have been studied in the electrocatalytic nitrate (NO3–) reduction reaction (NO3–RR) for a long time. However, few studies focused on horizontal comparison of CuNi, CuCo, and CuFe (abbreviated as CuM) NO3–RR ammonia synthesis. Herein, we prepare three series catalysts, with different atom ratios Cu/M (Cu/M = 7/3, 5/5, or 3/7) ordered mesoporous carbon (OMC) support (denoted CuM/OMC). The characterization results reveal that metallic particles Cu M components...
Abstract The introduction of enlarged and interconnected nanochannels into metal–organic frameworks (MOFs) overcome their micropore size restriction, enhances mass transportation, improves the accessibility anchored metal clusters. Herein, foamed Ce‐MOF single crystals (F‐Ce‐MOF‐SC‐x) designed from a multiscale co‐assembly is reported in presence copolymer template 1,3,5‐trimethylbenzene as structural regulator. resultant F‐Ce‐MOF‐SC‐x possessed well‐defined microporous tandem‐ordered...
Unique nanorod-like mesocrystals constructed from ultrathin rutileTiO2 nanowires were successfully fabricated for the first time using a low-temperature additive-free synthetic route, and mesocrystal formation requirements mechanism in absence of polymer additives discussed. The highly crystalline their diameters found to be ca. 3–5 nm. rutile TiO2 formed through homoepitaxial aggregation nanowiresvia face-to-face oriented attachment, accompanied promoted by simultaneous phase transformation...
Ru/CeO2 catalysts with different amounts of surface oxygen vacancies were prepared by changing the morphology CeO2. The conversion Ce4+ to Ce3+ and formation Ru–O–Ce bonds led enhancement amount vacancies. Ru species low crystallinity enriched Ru4+ ions exist on CeO2 nanorods, while metallic particles nanocubes. high concentration enhanced adsorption hydrogen nitrogen also desorption in form H2. Therefore, nanorods showed ammonia synthesis activities. On contrary, lower catalytic activity...
Classical amino-functionalized Fe-terephthalate metal-organic framework NH2-MIL-53(Fe) and its parent MIL-53(Fe) were prepared via simple hydrothermal methods. The catalytic performaces of these two Fe-MOFs explored for the selective oxidation H2S. physicochemical properties fresh used catalysts investigated by XRD, BET, SEM, FT-IR, CO2-TPD, XPS techniques. It was found that introduction amino groups reduces activation energies H2S endows this catalyst surface with moderate basic sites. As a...
The increase of alumina calcination temperature from 800 °C to 1300 results in the transformation γ-Al2O3 α-Al2O3 phase accompanying a decrease specific surface area and amount tetrahedral Al3+ sites. Over Ru–Ba/alumina catalysts, an would broaden size distribution Ru particles, enlarge metal-to-oxide ratio Ru, hydroxyl groups, as well lower for N2 desorption. As result, lessens effect hydrogen poisoning decreases activation energy ammonia synthesis. Ru–Ba/Al2O3 catalyst with calcined at 980...

This result can be attributed to intrinsic characteristics of nanowires. three-dimensional network could provide...
Amine‐impregnated adsorbents are promising alternatives to aqueous amines for CO 2 capture. However, the diffusion‐controlled adsorption process is a significant issue associated with them, resulting in insufficient utilization of amine groups. Herein, we propose use functionalized ionic liquids 1‐ethyl‐3‐methylimidazolium acetate ([emim][Ac]) chemical reactivity and low viscosity as additive amine‐impregnated adsorbents. The key that [emim][Ac] does not show drastic increase after reacting...

Abstract The industrial synthesis of ammonia (NH 3 ) using iron-based Haber-Bosch catalyst requires harsh reaction conditions. Developing advanced catalysts that perform well at mild conditions (<400 °C, <2 MPa) for application is a long-term goal. Here we report Co-N-C with high NH rate simultaneously exhibits dynamic and steady-state active sites. Our studies demonstrate the atomically dispersed cobalt weakly coordinated pyridine N reacts surface H 2 to produce via chemical looping...
