The catalytic conversions of biomass and its derivatives into fuels chemicals require active stable catalysts. Non-noble-metal catalysts typically suffer from deactivation due to the leaching sintering metal species in liquid-phase reactions. In this work, we report a facile synthesis porous-carbon-coated Ni supported on carbon nanotubes (CNFx@Ni@CNTs) by atomic layer deposition for reductive amination levulinic acid (LA) with amines pyrrolidones. Under protection porous moderate thickness,...
Thermochemical conversions are pathways for biomass utilization to produce various value-added energy and chemical products. For the development of novel thermochemical conversion technologies, an accurate understanding reaction performance kinetics is essential. Given diversity thermal analysis techniques, it necessary understand features limitations reactors, ensuring that selected reactor meets specific need characterization. This paper provides a critical overview reactors based on...
The europium complex Eu(TTA)3(TPPO)2 (TTA = thenoyltrifluoroacetone, TPPO triphenylphosphine oxide) was incorporated into poly(methyl methacrylate) (PMMA, Mw ≈ 350 000), polystyrene (PS, 250 poly(vinyl pyrrolidone) (PVP, 1 300 000) matrixes and electrospun various composite fibers. thermal stability of these fibers is better than that the pure complex. Their photoluminescence properties were studied in comparison to those results indicate that, all fibers, excitation bands ligands split...
Oxygen defects play a critically important role in redox reactions on ceria-based catalysts. Raman spectroscopy is key technique for the characterization of oxygen ceria However, assignment spectra has been dispute decades. In this work, combining density functional theory calculation with model composites, we resolved long-standing question catalysts at atomic level. The peak 460 cm–1 attributed to wagging vibration O atom between two Ce4+ ions, and its position varies length Ce—O bond band...
Direct synthesis of H2O2 from H2 and O2 is an environmentally benign atom economic process as such the ideal pathway in catalysis. However, currently no low-cost this kind catalysis exists, although it would be attractive alternative strategy to common industrial anthraquinone method for production. Metal-based catalysts are widely employed a direct but often need oxidized, alloyed, or supplied with additives make them selective. To understand metal-oxidation state heterogeneous catalysis,...
To further reveal the extraction model for selective separation of trivalent actinides over lanthanides by dithiophosphinic acids (DPAHs), five representative DPAH ligands with different substituent groups have been synthesized, and their complexation behaviors toward Am3+/Eu3+ investigated both experimentally theoretically. The introduction electron-withdrawing group −CF3 into is beneficial to extractability among ligands. Slope analyses show that Am3+ Eu3+ were extracted as...
Highly regioselective <italic>O</italic>-demethylation of aromatic ethers related to the bioconversion lignin was achieved by H<sub>2</sub>O<sub>2</sub>-dependent engineered P450BM3 enzymes with assistance a dual-functional small molecule (DFSM) for first time.
The development of very efficient bifunctional catalysts for the simultaneous detoxification two kinds deadliest chemical warfare agents (CWAs), nerve agent and blister agent, is highly desirable.

By performing density functional theory calculations, we show the mechanism details of CO oxidation catalyzed by several PtmAun (m + n = 4) clusters. It is found that in all situations, reaction prefers to proceed via single-center pathway two-center according a two-step mechanism: initial activation O2 molecule form peroxide-like intermediate followed rupture peroxide bond complete reaction. In Pt−Au bimetallic clusters, Pt sites are catalytically active centers, whereas Au "formally...
The measurement and analysis of reaction behavior, kinetics quantification, mechanism clarification for gas–solid reactions are essential to the research development process technologies in fields chemical engineering, energy production, mineral processing, etc. By far, different approaches instruments have been applied measurement, but a recent appears distinctive because its use micro fluidized bed (MFB) implementing so-called isothermal differential at Institute Process Engineering,...
By carrying out density functional theory calculations, we studied the CO oxidation promoted by cationic, neutral, and anionic Au trimers, which represent prototypes of Au-cluster-based catalysts with different charge states. The reaction is explored along three possible pathways: one involves initial complexes between trimers O2 CO; another related to interacting third refers a self-promoting mechanism; that is, second preadsorbed molecule. theoretical results show all species may promote...
Silk fibroin (SF) is a protein polymer derived from insects, which has unique mechanical properties and tunable biodegradation rate due to its variable structures. Here, the variability of structural, thermal, two domesticated silk films (Chinese Thailand B.

Central-to-axial chirality transfer via C–N single bond oxidation was first achieved as a versatile and conceptually distinct strategy to prepare new family of axially chiral heteroaromatic biaryl backbones P,N-ligands (named Quinoxalinaps) in gram scale. Two atropisomers Quinoxalinaps (ee >99%) were readily accessed from the same precursor enantiomer by simple dehydrogenative with MnO2 t-BuOOH under mild conditions. Phosphine could be introduced into ligands before or after control process....
Abstract Realizing the quantum anomalous Hall effect (QAHE) at high temperatures remains a significant challenge in condensed matter physics. MnBi 2 Te 4 , an intrinsic magnetic topological insulator, presents promising platform for QAHE. However, its inherent interlayer antiferromagnetic coupling hinders practical realization temperatures. In this study, we propose novel approach to achieve ferromagnetic (FM) MBT bilayer by intercalating septuple-layer of insulators XBi (X=Ge, Sn, Pb)....
