DEVELOPMENT OF NOVEL CATALYSTS AND PROCESSES FOR SUSTAINABLE HYDROGEN TECHNOLOGIES
… confinement effects. Notably, PtCu/1B shows 99% propylene selectivity for 100 hours at 500 °C, while Pt₁Zn₁ exhibits thermodynamic-limit efficiency at 550 °C. Plasma-treated Ni-Ce catalysts improve CO₂ methanation, and a CeO₂-based core@shell catalyst mitigates coking during DRM. For CDM, …

Synthesis, Characterization, Membrane Fabrication and Gas Transport Behavior of Liquid Crystal Polymer Materials
… solute sorption, diffusivity, permeability, and selectivity, and can thus be used to tune the transport and separation of different species. The current work has focused on polymer dispersed liquid crystal (PDLC), linear butadiene diol based side chain liquid crystalline polymer (LCP), and linear …

Selective deconstruction of polyethylene to propylene via isomerization/metathesis and 1-hexene isomerization studies
… where PE is selectively converted into propylene, a high-value monomer, via a tandem catalytic process combining dehydrogenation, isomerization and metathesis. Chapter 1 outlines the limitations of current recycling strategies and introduces chemical recycling as a promising route toward …

Conversion of waste organic carbon and nutrient streams to renewable fuels through integrated biological funneling and catalytic hydrothermal upgrading
… the depolymerization product of PHB) to produce propylene, with a focus on Brønsted-Lewis acidity of amorphous silica-alumina (ASAs) heterogeneous catalysts and longer-term time-on-stream experiments to explore catalyst deactivation mechanisms. The first research objective was addressed by …
