Tailoring the molecular environment around catalytically active sites allows for enhancement of catalytic reactivity through a hitherto unexplored pathway. In zeolites, presence water creates an ionic via formation hydrated hydronium ions and negatively charged framework aluminum tetrahedra. The high density cation-anion pairs determined by concentration zeolite induces local strength that increases excess chemical potential sorbed uncharged organic reactants. Charged transition states...
Abstract With the rapid development of industry, production dye waste-water has increased year by year. Dye composition complex, high concentration, and color, difficult to biodegradable substances, biodegrade. According chemical structure, dyes are mainly divided into eight categories, such as azo dyes; according application can be 14 reactive dyes, acid so on. Dyes show chroma contamination due presence chromophore in molecular structure. comes from dyestuff printing dyeing factory, wool...
The prevalence and perniciousness of fake news has been a critical issue on the Internet, which stimulates development automatic detection in turn. In this paper, we focus evidence-based detection, where several evidences are utilized to probe veracity (i.e., claim). Most previous methods first employ sequential models embed semantic information then capture claim-evidence interaction based different attention mechanisms. Despite their effectiveness, they still suffer from two main...
Com-paring mechanisms: The so-called hydrocarbon pool mechanism does not operate with zeolite ZSM-22 in the methanol-to-olefin (MTO) conversion process as a result of narrow channels (0.57 nm) its framework structure. However, this provided condition free secondary reactions for detailed mechanistic studies, H/D exchange patterns toluene suggesting paring mechanism.
Abstract The direct α‐alkylation of ketones with alcohols has emerged as a new green protocol to construct CC bonds H 2 O the sole byproduct. In this work, very simple and convenient Pd/C catalytic system for primary in pure water is developed. Based on system, aqueous mixtures dilute acetone, 1‐butanol, ethanol (mimicking ABE fermentation products) can be directly transformed into C 5 –C 11 or longer‐chain alcohols, which are precursors fuels.
Abstract Background With the increasing stress from oil price and environmental pollution, aroused attention has been paid to microbial production of chemicals renewable sources. The C12/14 C16/18 alcohols are important feedstocks for surfactants detergents, which widely used in most respected consumer cleaning products personal care worldwide. Though bioproduction fatty carried out engineered E. coli , several key problems have not solved earlier studies, such as quite low alcohol, lack...
Recyclable iridium catalysts have been developed rationally for the direct self-condensation of ethanol and butanol in water air.
Pd–FeO<sub>x</sub>/C catalysts were prepared and found to be efficient in succinic acid hydrogenation produce 1,4-butanediol one-pot.
C-H methylation is an attractive chemical transformation for C-C bonds construction in organic chemistry, yet efficient of readily available (bio)alcohols water using methanol as sustainable C1 feedstock limited. Herein, iridium nanocatalysts encapsulated yolk-shell-structured mesoporous carbon nanospheres (Ir@YSMCNs) were synthesized this transformation. Monodispersed Ir clusters (ca. 1.0 nm) situ and spatially isolated within YSMCNs by a silica-assisted sol-gel emulsion strategy. A...
Peaches are susceptible to infection from several postharvest diseases. In order control disease and avoid potential health risks, it is important identify suitable treatments for each type. this study, the spectral imaging information hyperspectral reflectance (400~1000 nm) was used evaluate classify three kinds of common peach disease. To reduce large dimensionality imaging, principal component analysis (PCA) applied analyse wavelength image as a whole, first selected extract features. A...
In this work, high-density jet fuel range cycloalkanes were synthesized in high yields (∼80%) by solvent-free aldol condensation of cyclopentanone and furfural followed hydrodeoxygenation (HDO). Sodium-promoted magnesium–aluminum mixed oxides (Na–MgAlO) exhibited a catalytic activity the under condition. Furfural conversion 99.4% with almost 100% selectivity for 2-(2-furylmethylidene) 2,5-bis(2-furylmethylidene) obtained over 5.7%Na–MgAlO catalyst mild conditions (80 °C, 2 h). The Na–MgAlO...
The presence of Zn can promote the activity and stability as well adjust product selectivity due to formation ZnCu alloy reduction acidic sites, which prevents deactivation catalyst dehydration 1,4-PDO.
Understanding the interaction between oxides and water is critical for designing many of their functionalities, including electrocatalysis molecular oxygen reduction. In this study, we probed hydroxylation model (001)-oriented La1–xSrxMnO3 (LSMO) perovskite surfaces, where electronic structure manganese valence were controlled by five substitution levels lanthanum with strontium, using ambient-pressure X-ray photoelectron spectroscopy in a humid environment. The degree hydroxyl formation on...
A powerful strategy for the regioselective bidirectional synthesis of unsymmetrically substituted ketones is described, relying on fact that exchange a xanthate much faster than radical addition to an unactivated alkene. The use alkene as formal "alkylating" agent associated with tolerance numerous functional groups and mildness experimental conditions removes many problems classical ionic transition-metal-based approaches.
Ethanol could be upgraded with methanol directly and selectively using precisely immobilized Ir catalysts.

Abstract Due to the advantages of non‐contact processing, high efficiency, precision, and superior controllability, laser lift‐off (LLO) technologies exhibit excellent material applicability process compatibility in ultra‐thin electronic devices. This brings new opportunities for large‐scale manufacturing emerging electronics that meet ultra‐thin, fragile, poor high‐temperature resistance. However, this opportunity also comes with formidable challenges from complex mechanisms laser‐matter...
