A Pyrrolidine Functionalized Poly[(ethylene glycol) Methacrylate] Resin as a Heterogeneous Catalyst for Aqueous Aldol Reactions
<p>This repository includes experimental data associated with the following publication: Biesemans, B.; Aljammal, N.; Radhakrishnan, S.; Breynaert, E.; Stevens, C.V.; Lauwaert, J.; Thybaut, J.W. A Pyrrolidine Functionalized Poly[(ethylene glycol) Methacrylate] Resin as a Heterogeneous Catalyst for Aqueous Aldol Reactions. Catalysts 2022, 12, 1389. https://doi.org/10.3390/catal12111389<br> In this study, a pyrrolidine group (AMP) was functionalized on a polymer resin (PEGMA). The synthesis procedure consists of suspension polymerization of the PEGMA resin, introduction of Cl groups (PEGMA-Cl), substitution of Cl groups by Boc-protected pyrrolidine groups (PEGMA-AMP-Boc) and deprotection of the pyrrolidine active sites (PEGMA-AMP). Three batches of PEGMA-AMP catalyst were synthesized with different loadings:<br> - PEGMA-AMP-1 with 0.054 mmol amines/g catalyst;<br> - PEGMA-AMP-2 with 0.190 mmol amines/g catalyst;<br> - PEGMA-AMP-3 with 0.270 mmol amines/g catalyst.</p> <p><br> The resulting PEGMA-AMP catalyst was characterized by <sup>1</sup>H- and <sup>13</sup>C-NMR, FTIR, Elemental Analysis, and a swelling assessment. The catalyst was furthermore assessed as aldol condensation catalyst in the aldol condensation of 4-nitrobenzaldehyde with acetone at 55 °C in a 50/50 vol% mixture of either acetone/water or acetone/n-hexane. The resulting data is presented in the article in both figures and tables.</p> <p>The <sup>1</sup>H- and <sup>13</sup>C-NMR data are available via https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/YQ4FYJ</p>
Dataset for 'Favorable trade-off between heat transfer and pressure drop in 3D printed baffled logpile catalyst structures'
<p>This data set was used to generate the results in the paper 'Favorable trade-off between heat transfer and pressure drop in 3D printed baffled logpile catalyst structures', published in Chemical Engineering Research and Design by Leon R.S. Rosseau, Jord T.A. Jansen, Ivo Roghair and Martin van Sint Annaland (https://doi.org/10.1016/j.cherd.2023.06.046).<br> The data is ordered first by configuration, then by gap spacing and finally by relative baffle length (if applicable). The heatrun case folders contain the temperature, wall-heat flux and velocity distributions at steady state with heated walls. The rtdrun case folders contain the pressure and velocity distributions at steady state without heated walls. The E-curve sampling is available as numpy array, as the storage requirements for all of the individual time steps are too high.</p> <p>This data set and the corresponding paper are based on research undertaken in relation to a project (ZEOCAT-3D) which has received funding from the European Union’s Horizon 2020 research and innovation program, under Grant Agreement No. 814548. The authors would like to thank the EU Horizon 2020 program for this opportunity.

Dataset of the article 'Charge accumulation kinetics in multi-redox molecular catalysts immobilised on TiO2'
<p>Data published in the article 'Charge accumulation kinetics in multi-redox molecular catalysts immobilised on TiO<sub>2</sub>', available at <a href="https://doi.org/10.1039/D0SC04344C">https://doi.org/10.1039/D0SC04344C</a>.</p> <p>Abstract: Multi-redox catalysis requires the accumulation of more than one charge carrier and is crucial for solar energy conversion into fuels and valuable chemicals. In photo(electro)chemical systems, however, the necessary accumulation of multiple, long-lived charges is challenged by recombination with their counterparts. Herein, we investigate charge accumulation in two model multi-redox molecular catalysts for proton and CO<sub>2</sub> reduction attached onto mesoporous TiO<sub>2</sub> electrodes. Transient absorption spectroscopy and spectroelectrochemical techniques have been employed to study the kinetics of photoinduced electron transfer from the TiO<sub>2</sub> to the molecular catalysts in acetonitrile, with triethanolamine as the hole scavenger. At high light intensities, we detect charge accumulation in the millisecond timescale in the form of multi-reduced species. The redox potentials of the catalysts and the capacity of TiO<sub>2</sub> to accumulate electrons play an essential role in the charge accumulation process at the molecular catalyst. Recombination of reduced species with valence band holes in TiO<sub>2</sub> is observed to be faster than microseconds, while electron transfer from multi-reduced species to the conduction band or the electrolyte occurs in the millisecond timescale. Finally, under light irradiation, we show how charge accumulation on the catalyst is regulated as a function of the applied bias and the excitation light intensity.</p>
Data from: TiO2–SiO2 supported MnWOx catalysts by liquid-phase deposition for low-temperature NH3-SCR
NH3-SCR is an environmentally important reaction for the abatement of NOx from different resources. MnO2-based catalyst has attracted significant attention due to the excellent activity. In this paper, a series of MnWOx/TiO2–SiO2 catalysts were prepared by liquid-phase deposition method. The catalysts were characterized by N2 adsorption/ desorption, XRD, TEM, XPS, FT-IR, H2-TPR, TG and water adsorption capacity. The existence of SiO2 improved the SO2 and H2O resistance of the MnWOx/TiO2–SiO2 catalyst without decreasing the NH3-SCR activity. Under the reaction conditions of 2608C and 60 000 ml . gcata h21 GHSV, the NO conversion was kept stable at about 95% for 140 min on stream. The excellent performance of MnWOx/TiO2–SiO2 catalyst is considered to be originated from the texture properties and active species dispersion improvement by SiO2 in the support and low-temperature preparation.
