This work demonstrates how push–pull substitution can induce spectral tuning toward the visible range and improve photoisomerization efficiency of azobenzene-based photoswitches, making them good candidates for technological biological applications. The red-shifted bright ππ* state (S2) behaves like lower more productive dark nπ* (S1) because less potential energy along planar bending mode is available to reach higher unproductive nπ*/S0 crossing regions, which are responsible quantum yield...
The growing demand of energy needs the search for alternative sources different to fossil fuels. use biomass as source is one most studied, because there are high value products that can be produced from biomass. One these γ-valerolactone, obtained furfural, which a derived product. To transform furfural into γ-valerolactone necessary bifunctional catalyst and hydrogen source. In this work, was using 2-propanol solvent donor on Zr supported sepiolite catalysts. It demonstrated sepiolite,...
Impact of stabilisers on the catalytic performance supported Au colloidal nanoparticles for liquid phase oxidation glucose to glucaric acid.
Supported on activated carbon gold colloidal nanoparticles have been prepared in the presence of stabilizing polymer PVA and PVP (polyvinylalcohol, polyvinylpyrrolidone). The effect to Au weight ratio was investigated, for synthesizing with different particle size distribution. By varying polymer/Au wt/wt ratio, mean diameters from 3 8 nm were synthesized. synthesized catalysts studied liquid phase oxidation 1,6-hexanediol (HDO) adipic acid under base base-free conditions. A range...
The depletion of fossil resources is driving the research towards renewable alternatives, like lignocellulosic biomass. Therefore, development efficient continuous-flow processes, allowing to achieve better productivity compared batch will play a crucial role in promoting sustainable transition. In this context, we report on continuous-flow, gas-phase, catalytic transfer hydrogenation (CTH) methyl levulinate and ethanol over zirconia catalysts, particular focusing effect two different...
Different series of Au on carbon catalysts were prepared via sol-immobilization to investigate the role polymers (polyvinylpyrrolidone PVP, polyethylene glycol PEG and polyvinyl alcohol PVA), employed as gold nanoparticle (NP) stabilizers, catalyst properties catalytic activity. The synthesized materials widely characterized with several techniques (DLS, XRD, TEM XPS) used in 5-hydroxymethylfurfural (HMF) oxidation produce 2,5-furandicarboxylic acid (FDCA). obtained results clearly...
Abstract To make pyrolytic bio‐oil useful as a transportation fuel, the oxygen content must be reduced, and this can carried out by using catalytic hydrodeoxygenation (HDO) reaction. The greatest challenge is associated with removal of strongly bound oxygenated groups without saturating aromatic ring while preserving number carbons. However, development stable catalyst that selectively remove such low hydrogen consumption still challenging. In context, systematic study on HDO vanillin...
Glucaric acid (GA) is one of the top 12 value added chemicals from biomass and this due to several applications that molecule its derivates can have in industrial fields. For reason, it interesting find a competitive way produce lignocellulosic feedstock, more details glucose. Therefore, our research focused on synthesis GA starting Glucose aqueous phase, using molecular oxygen as oxidant agent gold nanoparticles supported materials catalysts. All tests been carried out batch reactor...
The oxidative condensation of furfural and ethanol has been studied using supported gold colloidal nanoparticles. influence the nature stabilizer (polyvinylalcohol, polyvinylpyrrolidone), choice thermal treatment washing for removing stabilizer, on catalytic performance evaluated. Variation mean particle size surface coverage nanoparticles onto support were achieved by modifying to Au weight ratio. Thus, was varied in range 3-8 nm. results showed that ratio, catalyst, affect activity...
