Hydrogen has been considering as a promising renewable energy source and a viable alternative for fossil-fuels in the future[1,2].Hydrogen oxidation reaction(HOR)and its reverse reaction are two significant reactions for applying hydrogen as electrochemical *** the other hand,platinum is believed to be the best electrocatalyst for HOR,although several drawbacks including high cost,scarcity,low CO tolerance,and depressed catalytic activities in alkaline environments,hinder the development of hydrogen application[1].Hence,it is highly desired to develop Pt-free HOR catalysts with high activity,high stability,low cost,and good resistance to CO poisoning[3].

Tip-enhanced Raman spectrum(TERS) is a scanning probe technique for acquiring chemical information at high spatial resolution and with high chemical sensitivity. The sensitivity of TERS with atomic force microscopy(AFM) system is mainly determined by the metalized tips. Here, we report a fabrication protocol for AFM-TERS tips that incorporate a copper(Cu) primer film between a gold(Au) layer and a Si AFM tip. They were fabricated by coating the Si tip with a 2 nm Cu layer prior to adding a 20 nm Au layer. For top illumination TERS experiments, these tips exhibited superior TERS performance relative to that observed for tips coated with Au only. Samples included graphene, thiophenol and brilliant cresyl blue. The results may derive from the surface roughness of the tip apex and a Cu/Au synergism of local surface plasmon resonances.

The expression of chirality in 2D molecular assemblies on solid surfaces has unique features compared to the analogous process in 1D and 3D supramolecular assemblies. Understanding the formation of chiral molecular assemblies on surfaces not only provides insight into the origin and transfer of chirality in many enantioselective processes, but also aids rational design and construction of chiral architectures and materials. his present contribution reviews recent studies on how chirality is induced and expressed on the surface at diferent levels, both from intrinsically chiral and achiral molecules. Furthermore, we discuss the regulation efect of some pivotal factors, for example, the chemical structure, the chiral auxiliary molecules,and the assembled environments, on the expression of chirality in molecular assembly.
