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...
Efficient recovery of selenium from the dilute acidic solution is of great importance to the cleaner production of this scattered element. In order to overcome the bottlenecks of low recovery ratio and severe environment issues in conventional processes, an easy-operation electrochemical recovery process of Se was developed using low-cost stainless...
© 2018 The Royal Society of Chemistry. Ordered mesoporous carbons (OMCs) doped with nitrogen, phosphorus or boron were synthesised through a two-step nanocasting method and studied as electrocatalysts for the reduction of nitrobenzene to aniline in a half-cell setup. The nature of the dopant played a crucial role in the electrocatalytic performance...
© 2018 The Royal Society of Chemistry. Following current strong demands from, among others, paper, food and mining industries, a novel type of nanofiltration membrane was developed, which displays excellent performance in terms of selectivity/flux with a unique combination of chemical stability over the full (0-14) pH-range and thermal stability up...
A promising alternative route for the synthesis of three-dimensional Au dendrites was developed by direct electrodeposition from a solution of HAuCl4 containing 3-aminopropyltriethoxysilane (APTS). Ultraviolet-visible spectroscopy, fourier transform infrared spectroscopy and isothermal titration calorimetry were used to study the interaction of APT...
Carbon-supported Pt-Ru alloys with a Pt/Ru ratio of 1:1 were prepared by NaBH4 reduction at room temperature. X-ray diffraction (XRD) measurements indicate that the as-prepared Pt-Ru nanoparticles had a face-centered cubic (fcc) structure. X-ray photoelectron spectroscopy (XPS) analyses demonstrate that alloying with Ru can decrease the 4f electron...
Pd/C and Pd/Mg-Al-CO3 LDH (Pd/LDH) catalysts were prepared and their catalytic performances for methanol electro-oxidation in alkaline solution were investigated in this work. The result of cyclic voltammograms proves that Pd/LDH has a much higher specific activity than Pd/C. CO stripping results indicate that Mg-Al-CO3 LDH could facilitate the ox...
Catalyst supports are known to play a critical role in high catalytic performance. A novel nanostructured graphene was obtained by facile thermal treatment of the three-dimensional (3-D) graphene material. X-ray diffraction (XRD), scanning electron microscopy (SEM) and nitrogen adsorption results reveal that the new material is composed of smaller ...
Non-Pt noble metal clusters like Au clusters are believed to be promising high performance catalysts for the oxygen reduction reaction (ORR) at the cathode of fuel cells, but they still suffer big problems during the catalysis reactions, such as a large amount of the capping agents being on the surface and easy occurrence of dissolution and aggrega...
