“…15 Carbon films have also been produced from sucrose and H 2 SO 4 using polystyrene spheres as templates. 16 H 2 SO 4 has also been used as a reagent in HTC 17 of biomass and molecules and to produce sulfurdoped carbon dots from waste frying oil. 18 As HMF could be a future platform chemical and is a common intermediate in carbohydrate chemistry, the objective of this study was to derive highly porous humins from it.…”

Microporous Humins Synthesized in Concentrated Sulfuric Acid Using 5-Hydroxymethyl Furfural

A new class of highly porous organic sorbents called microporous humins is presented. These microporous humins are derived from sustainable and industrially abundant resources, have high heat of CO 2 sorption, and could potentially be useful for the separation of carbon dioxide from gas mixtures. Their synthesis involves the polymerization of 5-hydroxymethyl furfural (HMF) in concentrated sulfuric acid and treatment with diethyl ether and heat. In particular, the porosities were tuned by the heat treatment. HMF is a potential platform chemical from biorefineries and a common intermediate in carbohydrate chemistry. A high uptake of CO 2 (up to 5.27 mmol/g at 0 °C and 1 bar) and high CO 2 -over-N 2 and CO 2 -over-CH 4 selectivities were observed. The microporous humins were aromatic and structurally amorphous, which was shown in a multipronged approach using 13 C nuclear magnetic resonance and Fourier transform infrared spectroscopies, elemental analysis, and wide-angle X-ray scattering.

“…The fabrication of surfaces that exhibit nanoscale variations in their chemical properties, namely, nano-patterned metallic surfaces have received increasing attention in nanotechnology [1] due to their potential application in biosensors [2,3], data storage [4], photonics [3], catalysis and etching masks [5]. A variety of techniques have been developed for generating patterned surfaces including photolithography, electron beam lithography, and scanning probe lithography [1,2,4].…”

Nanosphere lithography using thermal evaporation of gold

2006

-Nanosphere lithography, which allows for the fabrication of patterned metal surfaces, is a simple, effective and unconventional technique that exploits a selfassembly process. Using this technique, polystyrene nanospheres with diameters of 500nm, and 1 m were assembled onto a 'muscovite' mica substrate in a hexagonally close packed monolayer array, to provide a physical mask for material deposition. Thermal evaporation was subsequently used to deposit gold through the nanosphere mask layer, to generate a periodic array of gold nanostructures. Upon changing the mask to a multilayered array of nanospheres, slightly more complex nanostructures were achieved. However due to thermal evaporation being a high temperature process the nanostructures obtained deviated from their predicted quasi triangular shape due to a slight annealing of the polystyrene mask.

“…Carbonization of sucrose ended up with the formation of glassy carbons. 50 Recently, NSL has been explored to fabricate metal oxide catalyst nanostructures. At present, conventional methods, such as salt precipitation, calcinations, and solid phase reactions, are the most widely used processes for fabrication of the metal oxide catalysts.…”

Nanosphere lithography (NSL) is an inexpensive, high throughput, materials general nanofabrication technique capable of producing a large variety of nanoscale structures including well-ordered 2 dimensional nanoparticle arrays. In this review, we will summarize the most recent advances in the fabrication of size-tunable nanoparticles using NSL. Four examples of new NSL-derived materials will be described: (1) The development of a method to release NSL nanoparticles from the substrate for applications in solution environments, (2) the fabrication of triangular nanoholes with reactive ion etching, (3) the electrochemical fine tuning of the structure of a silver nanoparticle and the wavelength of its localized surface plasmon resonance (LSPR), and (4) the growth of ultra thin protective dielectric layers on NSL-fabricated Ag nanotriangles using atomic layer deposition (ALD).
