Abstract The shape-selective catalysis enabled by zeolite micropore’s molecular-sized sieving is an efficient way to reduce the cost of chemical separation in industry. Although well studied since its discovery, HZSM-5′s capability has never been fully exploited due co-existence different-sized straight channels and sinusoidal channels, which makes p -xylene production from toluene alkylation with least m o continue be one few industrial challenges Rather than modifications promote...
Fluorescent nitrogen-enriched carbon nanodots (C-dots) of 1 to 3 nm were obtained through a one-pot reaction between melamine and glycerol. These C-dots show quantum yields up 22% high two-photon absorption cross-section. The TiO2 based photoanode sensitized by these is capable converting near IR photon energy photocurrent.
A novel method has been developed for homogeneous dispersion of metal nanoparticles inside short carbon nanotubes (CNTs) with an inner diameter smaller than 10 nm. The process involves controlled cutting pristine long nanotubesviaoxidation catalyzed by Ag or Fe and introduction the CNT channels using a wet chemistry aided ultrasonic treatment extended stirring. resulting particles are very uniform sizes in range 2–4 In addition, selective such on exterior surfaces open CNTs achieved...
With the shape selective zeolite catalyst, toluene alkylation with methanol to para-xylene (MTPX) technology could produce highly pure (PX) in one step. The lower feedstock cost and less energy consumption products separation make it more competitive compared current disproportionation route. Thus, MTPX is regarded as most reasonable production route for PX production. This article reviews strategies that applied preparation of high-performance catalysts MTPX, special focus on precise...
Mechanochromic, tough and healable polyurethane films are synthesized their properties thoroughly characterized. The optimum utilized to explore the potential applications of shape memory flexible capacitor devices.
Furfuryl alcohol (FA) is an important building block in polymer, food, and pharmaceutical industries. In this work, we reported the biocatalytic reduction of furfural, one top value-added bio-based platform chemicals, to FA by immobilized Meyerozyma guilliermondii SC1103 cells. The process was optimized, tolerance yeast strain toward toxic furfural evaluated. It found that 200 mM could be reduced smoothly desired product with conversion 98% selectivity >98%, while yield only approximately...
Fe-based catalysts are promising as inexpensive and nontoxic dehydrogenation catalysts, but the active phase has not been elucidated in CO2-assisted dehydrogenation. In this study, evolution of supported iron catalyst was studied with situ XRD, ex XPS, TEM, TG-DTA, experiments reaction atmosphere switching. The results show that original Fe2O3 is gradually reduced to α-Fe then carburized Fe3C a low CO2/i-C4H10 ratio feed atmosphere. serves an for i-C4H10 When CO2 introduced, also shows high...
In this paper, a new 3D discrete hyperchaotic system is constructed, and its Lyapunov exponent approximate entropy are calculated. We adopt the drive-response method self-adaptive to make reach synchronization, then design an encrypted transmission based on synchronization of system. synchronous system, initial value related hash speech signal chaotic designed. Some security analyses studied in detail.
Dynamic degradation occurs when chaotic systems are implemented on digital devices, which seriously threatens the security of chaos-based pseudorandom sequence generators. The shows complex periodic behavior, is often ignored by designers and seldom analyzed in theory. Not knowing exact period output key problem that affects application In this paper, two cubic maps combined, have symmetry reconfigurable form circuit. dynamic behavior map corresponding respectively, reasons for weak...
Nanocrystal HZSM-5 zeolite aggregates with different SiO2/Al2O3 molar ratios were prepared under low temperature and used to catalyze the conversion of methanol propylene butene. The coke location, content, species deposited on investigated. near-graphite carbon external surface (SiO2/Al2O3 ratio = 400) was distinguished by transmission electron microscopy (TEM) energy dispersive spectrometer (EDS). distributions in micropores spent revealed thermogravimetric analysis (TGA)...
When chaotic systems are used in different practical applications, such as secure communication and pseudorandom sequence generators, a large number of strongly required. However, for lack systematic construction theory, the mainly depends on exhaustive search parameters or initial values, especially class dynamical with hidden attractors. In this paper, quadratic polynomial maps is studied, general method constructing proposed. The proposed satisfy Li–Yorke definition chaos. This can...

Two modified zeolites, ZSM-5-Mg(OH)2 and ZSM-5-Mg(NO3)2, were achieved by Mg(NO3)2 impregnation methods with or without NH3·H2O as a precipitator, respectively. The Brønsted acid sites of ZSM-5 can be reduced Mg modification, especially for the strong acid. results from XRF XPS showed surface Mg-rich both zeolites. However, concentration on is significantly lower than that indicating addition in could suppress enrichment surface. methanol conversion significant effects Mg-modification method...
