[MAT-15]Vertically aligned macro-porosity for efficient ion transport in densely packed 2D-materials electrode structure

We design interconnected macro-hole array by different 3D printing models, to ensure the ion transport route in the highly stacked 2D laminate electrode. This method can achieve a combination of a bulk reservoir with nanochannel to accelerate the ion transport without mass loss. A vertical electric field controls the transport of nanoconfined ions. We also investigate the effect of the vertical channel distribution of different interspaced pores and the electrochemical performance with high mass loadings.

[MAT-12]Physical and electrochemical characterization of a Cu-based oxygen reduction hybrid membrane platform incorporating a proton transfer agent

A hybrid bilayer membrane (HBM) is constructed by appending a lipid monolayer on top of a self-assembled monolayer (SAM) with the incorporation of the alkyl phosphate proton carrier to study the O2 reduction reaction (ORR). The enhanced the current density of ORR dictates the electrochemical reduction activity and product selectivity of the underlying catalyst and provide a platform to examine the role of proton transfer kinetics in proton-coupled electron transfer (PCET) reactions.

[MAT-08]Multifunctional metal modified Janus tree

We design and synthesize a metal modified titania-silica tree for multifunctional autonomous motion. A versatile solution synthesis method is adopted for growing colloidal silica rod on the face of titania spheres, following by a hydrothermal growth of the titania head6. The gold nanoparticles are selectively loaded on the surface of the titania to form the metal modified Janus tree. By applying each triggering energy source, we can achieve rapid response of the metal modified Janus tree based on the propulsion mechanism of thermophoresis by Near-infrared light (NIR) irradiation, photochemically self-electrophoresis by multiwavelength irradiation, and induced-charge electrophoresis mechanism (ICEP) under AC electric field.
