Abstract Nickel‐nitrogen‐carbon single‐atom catalysts have attracted widespread interest for CO 2 electroreduction but they suffer from poor stability. Herein, we report on the preparation of Cl‐ and N‐doped porous carbon nanosheets with atomically dispersed NiN 4 Cl active sites (NiN Cl‐ClNC) through a molten‐salt‐assisted pyrolysis strategy. The optimized Cl‐ClNC catalyst delivers exceptional...

Surface oxidized carbon vulcane XC-72 is prepared as catalyst support and platinumnanoparticles are chemically anchored onto the modified surface. The nanoparticles of Pt weresynthesized by reduction of H2PtCl6 with sodium borohydride in a 5.5 M buffer solution ofsodium citrate; the complexation of citrate with metal ions is beneficial to the formation ofnanoparticles. The electro-oxidation of ...

Introduction: Data collected by the Mars Gamma Ray Spectrometer (GRS) orbiting aboard the 2001 Mars Odyssey spacecraft indicates that the global distribution of chlorine on Mars is heterogeneous [1]. The GRS 50% footprint has a diameter of ~440 km for low energy Cl lines and ~540 km for high energy Cl lines, however smoothing with a 10-degree radius filter is required to improve signal to noise...

Complexes of the type (η(3)-allyl)Pd(L)(Cl) and (η(3)-indenyl)Pd(L)(Cl) are highly active precatalysts for the Suzuki-Miyaura reaction. Even though allyl and indenyl ligands are similar to cyclopentadienyl (Cp) ligands, there have been no detailed comparative studies exploring the activity of precatalysts of the type (η(5)-Cp)Pd(L)(Cl) for Suzuki-Miyaura reactions. Here, we compare the catalyti...

This work has established the optimum reaction conditions in a biphasic system using microcrystalline cellulose as the raw material, an ionic liquid as the solvent, metal chloride as a catalyst, and an organic solvent as the extraction reagent. The optimum reaction conditions were microcrystalline cellulose:ionic liquid 1:10 (mass ratio), chromium(III) chloride (CrCl3) 6.8 mol% (based on the gl...

Fluorinated quaternary ammonium-containing polymers were used as catalyst binders in microbial fuel cell (MFC) cathodes. The performance of the cathodes was examined and compared to NAFION and other sulfonated aromatic cathode catalyst binders using linear sweep voltammetry (LSV), impedance spectroscopy, and performance tests in single chamber air-cathode MFCs. The cathodes with quaternary ammo...
