The use of renewable resources has gained attention in the last years due to the increasing worry about the environment. While wind, solar and hydropower can provide renewable energy (electricity), they cannot provide (bio)chemical molecules. For that, biomass is the only renewable option. In this thesis, I studied the conversion of biobased oils into chemicals. For this reaction, noble metals are efficient catalysts. Nevertheless, noble metals are scarce, hence expensive, which makes it desirable to find more abundant alternatives. Mo/W-carbides and Ni-phosphide are potential replacements of noble metals because they have similar electronic structures and are more available. I investigated the influence of several properties of carbides and phosphides in the biobased oil conversion, such as active phase, support, synthesis method and particle size. My findings enable to steer the selectivity of biobased oil conversion into specific products, which can be used to produce cosmetics, disinfectant, plastics, solvents and pharmaceutical products.
