Abstract for “Nanotechnological Processing of Catalytic Surfaces”
“Demanding chemical reaction typically requires a catalyst with three-dimensional form, rather than a flat top. One example is ethane hydrolysis. This can be achieved by inserting a 20-angstrom-diameter micro-particle made of surface nickel in the reactants over a truncated Octahedron base. High-temperature cooling techniques such as chill block melting and advanced nanotechnological processing will create a local atomically flat substrate. Nano-scale surface ripples can be created by placing the substrate under compressive stress, and then depositing a catalyst metal like nickel or platinum on it in an atomic layer deposition method. To mimic the geometry of bulk catalyst particles, the ripple wavelength and slope can be optimized in two dimensions. The modified rippled surface that is built over the substrate will exhibit the enhanced catalytic capabilities of the nanosphere catalyst but will also be attached to the substrate. This will give rise to a significant advantage over inserting catalytic particles in the reactant stream stream. The new surface will allow for much more efficient catalytic transformation of reactants flowing across it than a flat-metal catalytic surface. This modified surface can be used to make an automobile catalytic converter with a flow stream of hydrocarbons, which requires demanding catalytic reactions. It will also allow for construction of a converter that’s significantly smaller and more affordable than the current one. This technique can be used for any application, but it is also applicable to other types of catalytic reactions that require fixed catalytic surfaces.
