“…Succinic acid, along with FDCA, is one of the top value‐added chemicals from biomass identified by a recent US Department of Energy report . Electrochemical means to reduce maleic acid to succinic acid have been previously reported . Therefore, our future studies will identify factors that can suppress or enhance maleic acid formation so that we can obtain both FDCA and maleic acid as pure products.…”

Electrochemical Oxidation of 5‐Hydroxymethylfurfural to 2,5‐Furandicarboxylic Acid (FDCA) in Acidic Media Enabling Spontaneous FDCA Separation

2,5-Furandicarboxylic acid (FDCA) has become an increasingly desirable platform chemical to replace terephthalic acid in the production of a variety of polymeric materials, including polyethylene terephthalate. FDCA can be produced by the oxidation of 5-hydroxymethylfurfural (HMF), which can be derived from cellulosic biomass. Oxidation of HMF to FDCA is typically performed under basic conditions. Separation of FDCA is most easily accomplished by lowering the pH until FDCA is insoluble and filtering it from solution. In a large-scale process, this would lead to a high operating cost to purchase the required acid and base and to dispose of the resulting salt waste. In this study, electrochemical oxidation of HMF was carried out in acidic media by using a manganese oxide (MnO ) anode to remove the need to vary the pH to separate FDCA. The MnO anode afforded a FDCA yield of 53.8 % in a pH 1 H SO solution, in which FDCA precipitation occurred spontaneously from the same reaction solution without altering the pH or other aspects of the solution composition. Electrochemical oxidation in acidic media offers a new pathway to convert HMF into maleic acid, which is another desirable biomass-derived platform molecule. The performance of the MnO anode was investigated in comparison with that of a Pt anode to identify unique electrocatalytic properties of the MnO anode for HMF oxidation.

“…It could be seen that the redox couple in all cyclic voltammograms exhibited an increased current response with the increase of scan rate from 10 to 150 mV s -1 . The inset showed that the peak currents were directly proportional to square root of the scan rates, which demonstrated that the redox reactions on the Al-doped PbO 2 electrodes were a typical diffusion-controlled electrochemical process[39].…”

“…The particle size became smaller after Ce doping; this means that Ce ion doping can efficiently reduce the growth of particle size. 25 Nasir et al 26 have reported the increase in photocatalytic activities of TiO 2 nanoparticles. The increase in the activity can be attributed to the decrease in the particle size with the increase in the surface area of the samples.…”

Pure and Ce-doped TiO2 nanoparticles were prepared by facile sol–gel method. Structural, microstructural and optical properties were characterized by using X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL) and UV–Vis spectra. XRD analysis confirms the formation of pure anatase tetragonal TiO2 phase with a preferred orientation along (101) direction and that the lattice constants increased with increasing the Ce doping level. The UV–vis reflectance spectra showed that cerium doping shift in the absorption spectra to the visible region and lower the bandgap. All the Ce-doped TiO2 samples showed higher PL intensity than undoped TiO2. Sample containing 0.05 mol% Ce exhibited the highest PL intensity among the Ce-doped TiO2 nanoparticle samples. The visible emission peaks of pure and Ce-doped TiO2 nanoparticles are mainly associated with oxygen vacancies.
