1. Technologies related to renewable energy are well developed. However, this will not enable to cover the production of renewable materials, for which the use of sustainable carbon sources is inevitable.
2. Compared to other widely available biobased resources such as lignin and cellulose, glycerol has relatively simple chemical structure, which is beneficial for its exploitation as a platform molecule.
3. For the conversion of glycerol to sodium lactate under N2 at 240 oC, it is not
very likely that Cu2O is the active catalytic species with in-situ generated H2.
(D. Roy, et al. ACS Catal. 2011, 1, 548-551.)
4. Metallic sites and Lewis acid sites do not necessarily need proximity at the nanoscale level to obtain optimum catalytic performance. (Chapter 2 & 3) 5. In contrast to interactions between support and metallic sites, the
interactions between support and substrates, including solvents, are often unduly neglected. (Chapter 2 & 3)
6. Bimetallic sites often combine the advantages of both metals and thus exhibit improved performance in the (oxidative) dehydrogenation of glycerol. (Chapter 3 & 5)
7. Tuning the strength of metal-support interactions gives control over the oxidation state and dispersion of the metal species on the support. (Chapter 4 & 5)
8. When evaluating the applicability of metal-based catalysts, the TON should be considered in combination with the costs of the catalyst. (Chapter 4 & 5) 9. Milestones (like publications and conference presentations) let you know
where you are in a long PhD journey.
