“…Ethylene glycol (EG) and propylene glycol (PG) are known to be key precursors for pharmaceuticals, liquid fuels, emulsifiers, and surfactants (Harlin, 2011 ; Yue et al, 2012 ). One of the environmentally friendly ways of their syntheses is cellulose (a major component of biomass) catalytic hydrogenolysis in water.…”

Here, we discuss several important aspects of magnetically recoverable catalysts which can be realized when magnetic oxide nanoparticles are exposed to catalytic species and catalytic reaction media. In such conditions magnetic oxides can enhance performance of catalytic nanoparticles due to (i) electronic effects, (ii) catalyzing reactions which are beneficial for the final reaction outcome, or (iii) providing a capacity to dilute catalytic metal oxide species, leading to an increase of oxygen vacancies. However, this approach should be used when the magnetic oxides are stable in reaction conditions and do not promote side reactions. Incorporation of another active component, i.e., a graphene derivative, in the magnetically recoverable catalyst constitutes a smart design of a catalytic system due to synergy of its components, further enhancing catalytic properties.

“…Further, to study polyol blends, they should first-of-all be miscible in one another. Polyols are soluble in polar solvents and insoluble in non-polar solvents [51] although much details are unavailable on polyolpolyol solubility.…”

Polyols as Phase Change Materials for Low-grade Excess Heat Storage

et al. 2014

View full text Add to dashboard Cite

Polyols are an emerging phase change materials (PCM) category for thermal energy storage (TES), with moderate phase change temperatures and considerable enthalpies. These can be employed in systems for harvesting surplus energy from, industrial and power generation processes. However, knowledge on the properties of polyols in relation to desirable PCM properties is presently sparse and rather inconsistent. This work summarizes a literature review on polyols as PCM for TES. In addition, preliminary T-History characterization of some selected polyols was done. This study is expected to be an initiation of an extensive polyol phase equilibrium evaluation.

“…By means of selective oxidation, HMF can be converted to 2,5-furandicarboxylic acid (FDCA). Together with HMF, FDCA is known as a “sleeping giant” because of its enormous market potential [ 2 , 3 ]. For instance, FDCA can be used as an oil-free alternative to terephthalic acid in polymer manufacturing [ 4 ].…”

“…DMF is considered as a potential biofuel [ 6 ]. Meanwhile, the reduction of HMF gives 2,5-bis(hydroxymethyl) furan (BHMF), known as an intermediate in the pharmaceutical industry, and the synthesis of crown ethers and polymers [ 3 ]. In specific conditions, HMF can undergo a ring-opening reaction, where the main products are levulinic and formic acids [ 7 ].…”

Photocatalytic Oxidation of HMF under Solar Irradiation: Coupling of Microemulsion and Lyophilization to Obtain Innovative TiO2-Based Materials

et al. 2020

The photocatalytic oxidation of biomass-derived building blocks such as 5-hydroxymethylfurfural (HMF) is a promising reaction for obtaining valuable chemicals and the efficient long-term storage of solar radiation. In this work, we developed innovative TiO2-based materials capable of base-free HMF photo-oxidation in water using simulated solar irradiation. The materials were prepared by combining microemulsion and spray-freeze drying (SFD), resulting in highly porous systems with a large surface area. The effect of titania/silica composition and the presence of gold-copper alloy nanoparticles on the properties of materials as well as photocatalytic performance were evaluated. Among the lab-synthesized photocatalysts, Ti15Si85 SFD and Au3Cu1/Ti15Si85 SFD achieved the higher conversions, while the best selectivity was observed for Au3Cu1/Ti15Si85 SFD. The tests with radical scavengers for both TiO2-m and Au3Cu1/Ti15Si85 SFD suggested that primary species responsible for the selective photo-oxidation of HMF are photo-generated electrons and/or superoxide radicals.
