An environmentally benign and homogeneous base-free route for 5-hydroxymethyl-2-furfural (HMF) aerobic oxidation to 2,5-furandicarboxylic acid (FDCA) in water was reported using Mg–Al–CO3 hydrotalcite-supported Pd nanoparticles (xPd/HT-n) as catalyst. The influences of the Mg/Al molar ratio hydrotalcite loading amount on catalytic performance these catalysts were originally systematically investigated. These exhibited excellent activity FDCA selectivity HMF oxidation, especially 2%Pd/HT-5...

Single-crystalline Pd nanocrystals enclosed by {111} or {100} facets with controllable sizes were synthesized and originally employed as catalysts in the aerobic oxidation of 5-hydroxymethyl-2-furfural (HMF). The experimental results indicated that particle size exposed facet could obviously influence their catalytic performance. size-dependent effect this reaction only be derived from different dispersions. Therefore, was first investigated work through theoretical approaches. It found...

The aerobic oxidation of alcohols and aldehydes over noble metal catalysts is a critical reaction for the catalytic conversion carbohydrates into value-added chemicals from biomass. However, to fully understand mechanism, in particular, role O2 generated active oxygen species these reactions still challenging target. In present work, sub-10 nm Pt nanocrystals with cubic (Pt-NCs), octahedral (Pt-NOs), spherical (Pt-NSs) morphologies were synthesized used as 5-hydroxymethyl-2-furfural (HMF)....

The formation of crystalline multicomponent 2D lattices, containing more than two different organic molecular building blocks, has been rarely achieved because optimized recognition and selection processes require us to achieve the targeted surface confined patterns. In this Article, we show that tetraacidic azobenzene (NN4A) 1,3,5-tris(10-carboxydecyloxy)-benzene (TCDB) molecules can exclusively form phase-separated nanoporous networks via hydrogen bonds between carboxyl groups at...

Graphene (GP) field emitters fabricated by the electrophoretic deposition (EPD) and their emission performance can be enhanced tailed simultaneously chemical doping Au nanoparticles (NPs). It was found that doped NPs could both decrease resistance of GP increase density sites. The Au-doped showed lower turn-on voltage, threshold field, higher enhancement factor, luminance intensity, emitting uniformity, compared with pristine GP. This study will provide us to further understand role effect...

The nanoporous network formed by 1,3,5-tris(10-carboxydecyloxy) benzene (TCDB) was used as the host network. It has been identified that a variety of guest molecules (such triphenylene, 1-phenyloctane and copper(II) phthalocyanine (CuPc)) can be dispersed in this template to form binary supramolecular architectures, which were studied scanning tunneling microscopy (STM). is interesting observe adjust itself response molecular size shape guest, excluded some other molecules. dynamics CuPc...

In order to continuously update the prediction model based on ever-expanding data set solely, this study established a continual learning model, i.e. elastic weight consolidation (EWC)-based artificial neural network (ANN) predict hardness of Ni–Cu–CrBN coating that could be used in tribology field. The results showed after being trained by dataset, determination coefficient [Formula: see text] normal ANN old decreased 0.8421 while EWC-based was still 0.9836. It indicated presented good...
