We introduce a simple one-step method to synthesize MnO2/poly(3,4-ethylenedioxythiophene) (PEDOT) coaxial nanowires by coelectrodeposition in porous alumina template. Constant potential (typically 0.75 V vs Ag/AgCl) is applied on the bottom electrodes pores of template aqueous solution containing manganese acetate (10 mM) and EDOT monomers (80 mM). can easily control structures such as PEDOT shell thickness nanowire length varying potential. Electrochemical properties were investigated for...

Abstract Nowadays, highly active and stable alkaline bifunctional electrocatalysts toward water electrolysis that can work at high current density (≥1000 mA cm −2 ) are urgently needed. Herein, Mn‐doped RuO 2 (Mn x Ru 1‐x O nanofibers (NFs) constructed to achieve this object, presenting wonderful hydrogen evolution reaction (HER) oxygen (OER) performances with the overpotentials of only 269 461 mV 1 A in m KOH solution, remarkably stability under industrial demand , significantly better than...

We describe an efficient, bubble-free nanoscale motor consisting of a copper-platinum (Cu-Pt) segmented rod that operates as nanobattery in dilute aqueous Br(2) or I(2) solutions. The motion the is powered by self-electrophoresis caused redox reactions occurring on two different metal segments. Asymmetric ratchet-shaped pure copper nanorods were also found to rotate and tumble solution because ion gradient arising from asymmetric dissolution copper.

Oxidative desulfurization (ODS) of thiophene with hydrogen peroxide/acetic acid using a quaternary ammonium coordinated ionic liquid (IL) (C4H9)4NBr·2C6H11NO as an effective catalyst has been studied. The IL without fluorous anions is environmentally benign and easy prepare from cheap amines. Thiophene can be oxidized in the oil phase to greater polar sulfoxide, sulfone, SO42−. Most oxidation products transfer water for their higher property, resulting removal n-octane additional extraction...

Polybenzimidazoles (PBIs) have been investigated for use as gas separation membranes due to their thermal stability and good H2/CO2 performance at elevated temperatures. However, PBIs are hydrophilic, effects of water vapor on PBI essentially unexplored. This study investigates sorption, diffusion, dilation a commercial PBI, Celazole, recently synthesized sulfonyl-containing TADPS-TPA. Water binds strongly both polymers requires temperatures removal. sorption in Celazole follows dual-mode...
