In this work, Fe–Zn catalysts were prepared, characterized, and examined for the synthesis of linear high carbon α-olefins (LAOs; C ≥ 4) directly from CO2 hydrogenation. The relationship performance structure has been established to unravel role ZnO in bimetallic Fe5C2–ZnO catalysts. A Fe2Zn1 catalyst showed selectivity C2–C7 olefins (a 57.8% gas phase) after 200 h time-on-stream total C4+ liquid products 81.9% with 85.9% LAOs alkenes at a conversion 35.0%. dominant mechanism deactivation...
ZnO films prepared at different temperatures and annealed 900°C in oxygen are studied by photoluminescence (PL) x-ray photoelectron spectroscopy (XPS). It is observed that the PL of as-grown green luminescence (GL) yellow (YL) related, after annealing GL restrained YL enhanced. The O 1s XPS results also show coexistence vacancy (VO) interstitial (Oi) before quenching VO annealing. By combining two it deduced related to Oi defects, respectively.
CeO2 nanorods supported Co–CoOx catalysts showed high selectivity for higher alcohol synthesis (HAS) from syngas. The has found to increase with lowering the Co loadings, and value over Co1/CeO2 (19.86%) is twice than that Co5/CeO2 (8.67%). active sites at interfaces between Co0 CoOx, or say, pairs, have evidenced be responsible HAS. strong metal–support interactions retard reduction of CoOx stabilize intermediates such as CO–Coδ+. Likely, CO favors dissociating on metallic surface form CHx...
Abstract Understanding of dynamic structure active sites is paramount importance for rational design industrial catalysts. This work revealed the evolution iron phases CO 2 hydrogenation over iron‐based With a combination operando Raman spectroscopy and X‐ray Diffraction coupled with online gas chromatography, panoramic oxides (α‐Fe O 3 γ‐Fe ) during activation were elaborated, that is, α‐Fe (γ‐Fe )→α‐Fe 4 (γ‐Fe)→χ‐Fe 5 C (θ‐Fe C). Both carbides showed high catalytic activities while χ‐Fe...
Direct conversion of CO2 into linear α-olefins with Fe-based catalysts is promising both technically and economically. Al as a widely employed structural additive to CO/CO2 hydrogenation known exhibit side effect shifting the selectivity from olefins undesirable methane. Here, we report that by doping Zn binary Fe–Al spinel, ternary Fe–Zn–Al spinel catalyst could be obtained high space–time yield respect 150.8 mmolC·gFe–1·h–1 in reactions. Multiple situ/ex situ characterizations combined DFT...
Abstract Converting CO 2 into high value‐added chemicals by renewable energy directly alleviates the problem of resource shortages, while also reduces amount in atmosphere. Among various reduction methods, electroreduction has attracted much attention because its moderate operating conditions and a green easy‐to‐scale strategy. In this work, four catalyst enhancement mechanisms: synergistic effect, strain ligand defect effect are briefly described. Then, catalytic mechanisms C products fully...
Wurtzite GaN films have been grown on (001) Si substrates using γ-Al2O3 as an intermediate layer by low pressure (∼76 Torr) metalorganic chemical vapor deposition. Reflection high energy electron diffraction and double crystal x-ray measurements revealed that the thin of “compliant” character was effective for film epitaxially Si.
