The study aimed to prepare and characterize carbon black-and graphene-supported PtSn catalysts as possible electrocatalysts alternative for glucose oxidation. Carbon-based PtSn catalysts were successfully synthesized by the borohydride-facilitated reduction method as confirmed by energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) analyses. The XRD pattern also revealed the formation of PtSn nanoparticles of less than 5 nm size. The electro-oxidation of glucose on PtSn/C was

Three oxidation peaks at -0.8 V, -0.3 V, and 0.05 V, which correspond to the oxidation processes of glucose, were observed. The addition of a secondary metal, Sn, showed an enhanced catalytic activity of Pt towards glucose electro-oxidation. The optimization of metal loading and metal ratio using carbon black (XC-72) as support was studied and the results revealed that the optimum metal loading is 40% while the optimum PtSn ratio is 1:0.01 using the 40% metal loading. The lower amount of Sn added can lower the poisoning effect of Pt and thus only act as a promoter. The optimized parameters for carbon black were used for graphene as support. The data revealed that graphene as a support has an enhanced electrocatalytic activity compared to carbon black with a peak current of 12.82 mA/cm 2 and 6.97 mA/cm 2 , respectively. The XRD data indicates that graphene is a promising support material that could modify the catalytic properties of PtSn bimetallic electrocatalyst for fuel cell catalysis.

DEDICATION This thesis is dedicated to my parents, Jose Solarte and Maria Rueda, great role models and friends, who have always assisted me and helped me any way they could; and to the rest of my family, for always believing in me, inspiring me, and encouraging me to reach higher goals. To all of them I want to say "Thank you", for being the best family that I could ever have.

Finally, I would like to thank my good friends Cristina Zaharia, Archana Niranjan, and Fernando Parrado, for all their encouragement and their invaluable friendship. iii ABSTRACT Data mining is the process of discovering correlations, patterns, trends or relationships by searching through a large amount of data stored in repositories, corporate databases, and data warehouses. Industrial engineering is a broad field and has many tools and techniques in its problem-solving arsenal. The purpose of this study is to improve the effectiveness of industrial engineering solutions through the application of data mining. To achieve this objective, an adaptation of the engineering design process is used to develop a methodology for effective application of data mining to databases and data repositories specifically designed for industrial engineering operations. This paper concludes by describing some of the advantages and disadvantages of the application of data mining techniques and tools to industrial engineering; it mentions some possible problems or issues in its implementation; and finally, it provides recommendations for future research in the application of data mining to facilitate decisions relevant to industrial engineering. iv
