In situ hydrogen peroxide (H2O2) production by two-electron oxygen reduction reaction (2e-ORR) is limited by sluggish dynamics which are divided into molecule transfer and reaction kinetics. Ordered matrix and disordered edge is synthesized to regulate molecules and electrons transfer. Interface Atomic Domains (IAD) are used to regulate the dynamic...

Squaric acid (SA) has been investigated as a readily available organic anode material in rechargeable lithium batteries. To overcome both conductivity and dissolution problems related to organic compounds, SA was conformally coated with conductive polyaniline through a facile in situ chemical polymerization route. Polyaniline-coated SA exhibits a s...

We synthesized ordered mesoporous Fe/N/C with highly active Fe-N-X/C sitesdenoted as m-FePhen-C as a non precious metal catalyst (NPMC) for the oxygen reduction reaction in fuel cells. This was the first study that incorporated a catalyst precursor with Fe-N coordination directly in a simple block co-polymer-assisted soft template method for the sy...

To promote the oxygen reduction reaction of metal-free catalysts, the introduction of porous structure is considered as a desirable approach because the structure can enhance mass transport and host many catalytic active sites. However, most of the previous studies reported only half-cell characterization; therefore, studies on membrane electrode a...

Well-defined core shell gold [email protected] nanocrystals ([email protected]) are facilely prepared by a simple and green wet-chemical method at 25 degrees C. A Good's buffer, 2-[4-(2-hydroxyethyl)-1-piperazinyl] ethanesulfonic acid (HEPES), is used as a reducing agent and a shape-directing agent, while there is no template, seed, organic solvent, or sur...

Nano-scale Pt particles are often reported to be more electrochemically active and stable in a fuel cell if properly displaced on support materials; however, the factors that affect their activity and stability are not well understood. We applied first-principles calculations and experimental measurements to well-defined model systems of N-doped gr...

One of the biggest challenges of 21st century is to develop powerful electrochemical energy devices (EEDs). The EEDs such as fuel cells, supercapacitors, and Li-ion batteries are among the most promising candidates in terms of power-densities and energy-densities. The nanostructured materials (NSMs) have drawn intense attention to develop highly ef...
