Article Abstract
Core-shell and hierarchical Pd-Cu nanowires, with exposed strained Cu(100) and Cu (100)/Cu(111) surfaces, respectively, were constructed. The hierarchical Pd-Cu demonstrated superior overall activity, ethylene selectivity, and reaction kinetics toward the electrochemical CO2 reduction reaction. Theoretical calculations indicate that the lattice-expanded Cu (100)/(111) interface effectively reduces the energy barrier for C2 production.

A series of Pd nanocluster (PdNC) catalysts -PdNCs/CuCoAl(O)/rGO- (: Pd loading (= 0.04-0.24 wt %), = 260-340 °C) are synthesized by loading water-soluble captopril-protected PdNCs on CuCoAl-layered-double-hydroxide/reduced-graphene-oxide using electrostatic adsorption followed by proper calcinations.

In this work, a simple post-treatment has been carried out on a solid palladium-copper alloy to enhance the ethylene selectivity without any loss of activity. In all catalysts, PdCu/C catalysts post-treated at 375 °C exhibit improved ethylene selectivity (86%) compared to the solid PdCu/C catalysts (61%) at 100% acetylene conversion with comparable catalytic activity. During the post-treatment, the average size of PdCu nanoparticles is maintained at 6.

We propose and test a hierarchical high-throughput screening (HHTS) approach to catalyst design for complex catalytic reaction systems that is based on quantum mechanics (QM) derived full reaction networks with QM rate constants but simplified to examine only the reaction steps likely to be rate determining. We illustrate this approach by applying it to determine the optimum dopants (our of 35 candidates) to improve the turnover frequency (TOF) for the Fe-based Haber-Bosch ammonia synthesis process. We start from the QM-based free-energy reaction network for this reaction over Fe(111), which contains the 26 most important surface configurations and 17 transition states at operating conditions of temperature and pressure, from which we select the key reaction steps that might become rate determining for the alloy.

The synergetic effect of alloy and morphology of nanocatalysts play critical roles towards ethanol electrooxidation. In this work, we developed a novel electrocatalyst fabricated by one-pot synthesis of hierarchical flower-like palladium (Pd)-copper (Cu) alloy nanocatalysts supported on reduced graphene oxide (Pd-Cu/RGO) for direct ethanol fuel cells. The structures of the catalysts were characterized by using scanning electron microscopy (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectrometer (XPS).
