Advanced Manufacturing And Nanotechnology For Non-Noble Metal-Based Oxygen Evolution Electrocatalysts, Bowei Zhang Jan 2019

Advanced Manufacturing And Nanotechnology For Non-Noble Metal-Based Oxygen Evolution Electrocatalysts, Bowei Zhang

Graduate Theses and Dissertations

The oxygen evolution reaction (OER) plays vital roles in electrochemical energy conversion and storage applications, including water-splitting systems, fuel cells, metal-air batteries, and CO2 reduction devices, but the development of highly active and robust OER catalysts based on non-noble metals by simple methods is challenging. In this dissertation, three major strategies are proposed for developing advanced OER electrocatalysts at low cost by simple and versatile methods. In the first work, a bimetallic Ni-Fe-P nanosheet arrays were designed and fabricated as a pre-catalyst to catalyzing super high OER current densities under alkaline and neutral media. To catalyze a 10 mA/cm2 ...


An Agent-Based Approach To Modeling Sustainable Sociotechnical Systems, Anuj Mittal Jan 2019

An Agent-Based Approach To Modeling Sustainable Sociotechnical Systems, Anuj Mittal

Graduate Theses and Dissertations

A gradual evolution in the food and energy sectors towards decentralized decision-making is requiring participant organizations to consider new approaches to the design of policies and processes. Increasing consumer preference for food sourced from small-scale regional farmers has led to changing logistics requirements. Similarly, as consumers have become conscious of the impacts of climate change on the environment, they have begun to adopt renewable sources to meet their energy needs. Moreover, the emergence of new technologies has enabled consumers to generate their own energy. Such shifts in decision-making power to consumers necessitates the consideration of their perspectives and preferences when ...
