Haoxiang Yan - Inorganic Chemistry and Catalysis

Research

In this research, advanced active, and robust catalyst materials for highly selective and precise metathesis of PE (LDPE, LLDPE, etc.), into a range of medium-sized alkanes (C₆-C₁₈) will be developed. Mechanistic insights in the functioning of the various dehydrogenation/hydrogenation, isomerization, and metathesis active sites will be obtained by spectroscopy and microscopy for important structure-performance relationships guiding further catalyst materials design. Each of the different active sites will be optimized towards optimal conversion, and sufficient stability towards poisoning. The latter aspect will not only lead to formulation of catalyst powders commonly used in research for PE conversion into alkanes, but also in the synthesis and design of real-life catalyst bodies, enabling the conversion of real-life PE containing various contaminants and impurities within reactors.

abstract = {Turning waste into valuable products is one of the main challenges of the chemical industry. In this work, chitosan (CS), an abundant, low‐cost, and non‐toxic biopolymer derived from chitin, was reshaped into beads of ~ 3 mm. Their suitability as a support material for active phase catalyst materials was tested for a zirconium‐based Metal‐Organic Framework (MOF) with incorporated Pt, namely UiO‐67‐Pt. Its incorporation was investigated via two procedures: a one‐pot synthesis (OPS) and a post‐synthetic functionalization (PSF) synthesis method. Scanning electron microscopy (SEM) images show good UiO‐67‐Pt dispersion throughout the CS beads for the one‐pot synthesized material (UiO‐67‐Pt‐OPS@CS). However, this uniform dispersion was not observed for the post‐synthetically functionalized material (UiO‐67‐Pt‐PSF@CS). The success of the implementation of UiO‐67‐Pt was evaluated with ultraviolet‐visible and infrared spectroscopy for both composite materials. Thermogravimetric analysis reveals higher thermal stabilities for UiO‐67‐Pt‐OPS@CS composite beads in comparison to pure CS beads, but not for UiO‐67‐Pt‐PSF@CS. The study provides valuable insights into the potential of chitosan as a green, bead‐shaped support material for MOFs, offering flexibility in their incorporation through different synthesis routes. It further contributes to the broader goal of the sustainable and eco‐friendly design of a new generation of catalysts made from waste materials.},
