Zn Lewis acid centers were grafted onto the silanol nest created by dealumination of H-BEA zeolite (DeAlBEA). The resulting material was characterized and investigated for propane dehydrogenation to propene n-butane 1,3-butadiene (1,3-BD). For Zn/Al molar ratios (Al is amount in H-BEA) below 0.12, sites are present as isolated (≡SiOZn–OH) species, but between 0.12 0.60, ≡SiOZn–OH species form nests which enhanced electron transfer O atoms neighboring group H-bonding interaction adjacent...
Isolated hafnium (Hf) sites were prepared on Silicalite-1 and SiO2 investigated for acetone conversion to isobutene. Characterization by IR, 1H MAS NMR, UV–vis spectroscopy suggests that Hf atoms are bonded the support via three O have one hydroxyl group, i.e, (≡SiO)3Hf–OH. In case of Hf/Silicalite-1, Hf–OH groups hydrogen bond with adjacent Si–OH form (≡SiO)3Hf–OH···HO–Si≡ complexes. The turnover frequency isobutene formation from is 4.5 times faster over Hf/Silicalite-1 than Hf/SiO2. Lewis...
An interest in the on-purpose production of 1,3-butadiene (1,3-BD) has grown, as a consequence decline naphtha cracking for ethene and propene, products that can now be produced economically by thermal dehydrogenation ethane propane contained natural gas. In this study, mechanism kinetics n-butane to 1,3-BD are explored over atomically distributed Pt sites grafted onto dealuminated zeolite BEA (DeAlBEA) form (≡Si–O–Zn)4–6Pt complexes. Reaction carried out at 823 K with 2.53 kPa n-butane/He...
The nanocrystals of CeF3 with the hexagonal structure and different morphologies such as disk, rod, dot have been successfully synthesized via a mild ultrasound assisted route from an aqueous solution cerium nitrate fluorine sources (KBF4, NaF, NH4F). use has remarkable effect on morphology final product. luminescence UV−vis absorption properties investigated. Compared other shape nanocrystals, intensity disklike is obviously enhanced. It suggested that function-improved materials could be...
Metal salts and 3/4-pyridyltetrazoles (3/4-Hptz) react with oxalic acid (H2ox), 1,2,4,5-benzenetetracarboxylic (H4btec), isophthalic (H2ip), 1,2,3,4-butanetetracarboxylic (H4btca) to afford six coordination polymers, namely, [Cu(4-ptz)(ox)0.5]n (1), [Cu(4-Hptz)(btec)0.5]n (2), [Co2(3-ptz)(ip)(OH)(H2O)]n (3), {[Co1.5(3-ptz)(btca)0.5(H2O)]·H2O}n (4), {[Co3(4-ptz)2(btca)(H2O)3]·2H2O}n (5), {[Cd2(4-ptz)2(btca)0.5(H2O)3]·DMF·4H2O}n (6). Their structures were characterized by EA, IR, PXRD, TGA,...
The decomposition of porous zeolitic-imidazolate frameworks (ZIFs) poses a significant challenge in discovering new melt-quenched ZIF glasses characterized by high porosity. This has sparked tremendous interest among scientists, driving...
To evaluate the potential of phase-change materials (PCMs) in improving indoor thermal and airflow environment Trombe walls under solar energy limitations, a computational fluid dynamics (CFDs) model was employed this study to perform comparative simulations. Taking traditional (TWs) as control group PCM-Trombe (PCM-TWs) experimental group, simulation analysis carried out based on meteorological data from typical spring day Hangzhou 2024. The results indicate that application PCM...
