Heterogenous Reduction Of Co2 Over Boron-Rich Alb2, Jose C. Berger
Heterogenous Reduction Of Co2 Over Boron-Rich Alb2, Jose C. Berger
Honors Undergraduate Theses
Evidence suggests that the recent drastic changes in the global climate have been caused by greenhouse gases, especially CO2. As a result, scientists are aiming to develop processes that either minimize the production of these gases or convert them into products of higher value. To that end, the catalytic properties of a two-dimensional boron-rich material were investigated. Herein is reported that such a material can reduce CO2 into benzene, C3 species, and C4 species at relatively low temperatures (225-450 ℃) and pressures (0.38 MPa). Current data suggest that a low-temperature induction period (e.g., 225 ℃) …

Mechanochemically Synthesized Cobalt Oxide-Based Particles For The Reduction Of Nitrophenols And Impacting Factors To Its Mechanism, Lorianne R. Shultz
Honors Undergraduate Theses
Mechanochemically synthesized cobalt oxide-based particles are employed for the catalytic reduction of 4-nitrophenol (4NP), a toxic water contaminant. This reduction produces 4‑aminophenol (4AP), a less toxic, pharmaceutical precursor for drugs such as paracetamol. The indicated reduction has been completed previously using noble metals and/or catalysts requiring extensive solvent use, and time as part of their preparation. The cost and synthesis of these noble metal catalysts hinders the sustainable broad scale application as an environmental remediation solution. The catalyst synthesis explored in this study utilizes the green chemistry technique of vibratory ball-milling and annealing cobalt oxide-based particles at different temperatures, producing …
