Book Description
Physical stabilization of nanoparticles against sintering by encapsulation within thin, porous, inert matrices is one approach to create catalysts with extended lifetimes. We have worked to develop versatile solution-based (i.e. low cost, high-yield) synthetic methods to stabilize nanoparticles while maintaining access to active sites.

Book Description
Electrocatalysis as an emerging clean energy strategy provides promising future application compared to conventional power solutions. However, the barriers to wide adoption remain challenging, such as catalyst price, storage weight, durability in extreme environment, fuel safety issues and its availability to the public. Recent advances in nanomaterial and nanotechnology enables rational design and synthesis of new catalysts with enhanced performance for heterogeneous electrocatalysis. Herein we propose the Nanoscale Design and Engineering of Electro-catalysts in Fuel Cell and Water Electrolyzer Energy Conversion. This dissertation provides some successful examples of electrode catalyst design and fabrication for boosting electrocatalysis in fuel cell and electrolyzer. Special emphasis is put on theories, synthesis strategies, performance boost to achieve the goal of enhancing catalyst activity whiling reducing materials cost; identifying durability issues and giving solutions; realizing low total over potential in bifunctional electrocatalysis and predicting catalyst performance from simulation to find out ideal composition. The engineered nanomaterials in this dissertation mainly take advantages of (1) optimization of nanoparticle size by novel support (Nb doped TiO2) or synthesis method (polymer-assisted chemical solution) to increase electrochemical active surface area for enhanced charge transfer and catalysis activity (Chapter 2, 3, and 4), (2) synergistic effect from support material (TiO2 for Pd, carbon materials for perovskite oxide) to improve nanoparticle deposition and exposure during reactions (Chapter 2, 3, and 4), (3) tunable electronic structure (A-site deficiency, A-site excess, and partially substitution of B-site transition metal cations) on cost-effective perovskite catalyst to replace noble metal (Pt, IrO2) for bifunctional oxygen electrocatalysis in unitized fuel cells (Chapter 3 and 4), and (4) activity description from atomic level to understand electrocatalysis mechanism and make prediction for new catalysts (Chapter 4 and 5). Pd on Nb-TiO2-C supports has increased reaction intensity, selectivity without sacrifice of durability. A-site nonstoichiometry and B-site doping successfully enhances oxygen bifunctionality of cost-effective perovskite catalysts; First-principle study suggests new Pd-Cu composition to achieve a balance between reaction activity and expense.
