The widespread utilization of renewable energy sources is essential to provide a long-term healthy living environment for a growing global population. Research shows that current conventional energy extraction and consumption methods are detrimental to our planet's climate and prolonging these methods will hinder the livelihood of plants, animals, and humans worldwide. This paper aims to better understand and improve on two well-known energy related reactions, 1) Fischer-Tropsch (FT) process 2) Oxygen Evolution Reaction (OER) through nanoscale engineering of catalytic supports and electrocatalysts, respectively. Poor diffusion of gaseous intermediates has served as a major bottleneck in widespread use of the FT process, while the OER suffers from the low accessibility of cost-effective electrocatalysts.Hierarchically porous SiO2 supports consisting of both mesopores and macropores were synthesized in a 2-step process to simultaneously improve mass transport of gaseous intermediates, while maintaining high metal dispersion for the FT process. Samples with varying mesopore diameter and similar macropore diameter were achieved and characterized. Samples were impregnated with Co3O4 as confirmed by elemental mapping and powder X-ray diffraction. Bimetallic and trimetallic layered double hydroxides (LDHs) were systematically synthesized to elucidate the role of Fe in OER electrocatalysts. Neutron total scattering experiments combined with cyclic voltammetry demonstrated the E1/2(Ni2+/3+) values inversely correlated to the Ni-O bond lengths, but not with activity. Trimetallic LDHs demonstrated a synergy between Ni and Fe that is disrupted by the introduction of another trivalent metal cation. Overall, nanoscale engineering remains key to understanding and improving the efficiency of energy related processes.
