Abstract null null Modifying the valence of metal active center to the favorable configuration offers a promising strategy to promote the electrocatalytic performance of water splitting. For example, Co2+ is reported to show better performance of water oxidation than Co3+ in the Co-based spinel oxide, but its adjustment degree is small due to the geometrical occupation and the uniform synthetic environment. In this work, on the basis of chemical tailoring for the Ni-doped CoFe Prussia blue precu...

Abstract null null Under vacuum conditions, the polar surface ZnO(0 0 0 1) evolves in time forming a layer with H and additional O which changes the top layer stoichiometry and other properties such as its work function. In this work we present a study of the evolution of the ZnO(0 0 0 1) surface in ultra-high vacuum performed with time of flight direct recoil spectroscopy to detect the adsorbed H and O, plus other standard techniques including photoelectron spectroscopy and low energy electron ...

Abstract null null Combining the first principles calculations and the non-equilibrium Green’s function formalisms, we decipher the structural, electronic, and transport properties of boron phosphide (BP) with hydrogenation. Hydrogenated BP monolayer is an indirect semiconductor with a wide-bandgap of 3.76 eV that is favorable in power devices. We find that the electronic properties are dependent of the stacking orders and the binding strength of the AA-, AB-, and AE-stacked patterns are stronge...

Abstract null null Two-dimensional (2D) 2H-1 T′ heterojunctions based on transition-metal dichalcogenides have attracted great attention due to their special interface structures and novel properties. Understanding the growth mechanism and the interface structures is essential for their controllable growth. In this work, we successfully synthesize lateral and vertical MoS2/ReS2 heterojunctions by using a two-step chemical vapor deposition (CVD) method, and deeply explore the evolution of the str...

Abstract null null Li dendrite growth and poor Coulombic efficiency still prevent the practical use of Li metal anodes. Here, we report a stable solid electrolyte interphase (SEI) layer consisting of Li3N and LiF by employing lithium nitrate (LiNO3) in carbonate electrolytes for the improved cycle performance with dendrite-free Li deposition for Li metal anodes. We demonstrate that the lower charge transfer activation energy is realized with the Li3N-rich SEI layer and LiF-rich SEI layer in carb...

Abstract null null The electrochemical nitrogen reduction reaction (NRR) is regarded as the most promising alternative to the traditional Haber-Bosch route in current context of developing sustainable and green technologies. However, challenges around low kinetics and low selectivity of NRR are significant barriers for this enticing goal. Different from the transition metal-based NRR catalysts that are prevalent in artificial nitrogen fixation, here, novel p-block non-transition metal catalysts,...

Abstract null null Hydrophobic charge-induction chromatography (HCIC) is a novel technology for antibody purification. The interaction between immunoglobulin G (IgG) and HCIC ligands was investigated by dissipative quartz crystal microbalance (QCM-D). HCIC ligands 2-mercapto-1-methylimidazole (MMI), 2-mercaptobenzimidazole (MBI) and 2-mercapto-4-methylpyrimidine hydrochloride (MMp) were coupled to the surface of a self-assembled monolayer (SAM) terminated by epoxy groups. The ellipsometric ligan...

Abstract null null Carbon nanotubes were modified towards oxygen reduction and evolution reactions by incorporation of cobalt and/or iron phthalocyanines (CoPc and FePc, respectively). The obtained monometallic samples were physically mixed in different ratios to assess the importance of each phthalocyanine. The increase of FePc content enhanced the electroactivity towards the oxygen reduction reaction, especially the limiting current density and reaction mechanism, for which two relationships w...

Abstract null null For the synthesis of cyclic carbonates from CO2 and epoxides, coordinatively unsaturated metal sites of metal-organic frameworks (MOFs) could play a vital role as active Lewis acid centers for facilitating the ring-opening of epoxides. Hence, constructing open metal sites (OMSs) on MOFs will be an effective strategy to improve their catalytic activity for the CO2 cycloaddition reaction. Herein, a simple thermal treatment method is performed on [Zn2(iso)2(bpy)2]n to regulate it...

Abstract null null The gas cluster ion beam (GCIB) is a valuable tool for surface analysis, providing new 3D mass analysis equipment possibilities. The main feature of the GCIB is that many particles are involved during the collision of the cluster ion beam with a sample surface. Studying the characteristics of the GCIB is essential for improving the performance of the analysis equipment. We evaluated the efficiency of the GCIB using a mixed-gas of Ar and CO2 as a primary ion beam for time-of-fl...
