Abstract

Dual-ionic pyrazolium salts have in this work been synthesized and shown to catalyze the coupling reaction of carbon dioxide (CO2) with epichlorohydrin achieving a 90% yield under 30 °C and 0.1 MPa CO2pressure. With the aid of a small amount of water, the product yield is greatly improved up to 99.5% under the same reaction conditions, which corresponds to a rate enhancement of up to 1.4 times for the formation of the carbonate. We propose and explore a dual origin of the role of water, first by affecting the gas to liquid mass transfer of CO2, and second a mechanism where water triggers a proton transfer that in turn underlies efficient conversion of CO2. This theoretically derived mechanism is also confirmed by 13C NMR and FT-IR spectroscopy results. The catalyst was found to be reusable eight times without obvious reduction of catalytic activity. The finding presented that an already efficient reaction to attract CO2is further greatly promoted only by the addition of water which can have important ramifications for green technology.

Abstract

Magnesium (Mg)‐ion batteries with low cost and good safety characteristics has attracted a great deal of attention recently. However, the high polarity and the slow diffusion of Mg2+ in the cathode material limit the development of practical Mg cathode materials. In this paper, an anion‐rich electrode material, NiS2, and its composite with Ni‐based carbon nanotubes (NiS2/NCNTs) are explored as the cathode materials for Mg‐ion batteries. These NiS2/NCNTs with excellent Mg2+ storage property is synthesized by a simple in situ growth of NiS2 nanoparticles on NCNTs. NiS2 with both a large regular cavity structure and abundant sulfur‐sulfur (SS) bonds with high electronegativity can provide a large number of active sites and unobstructed transport paths for the insertion–disinsertion of Mg2+. With the aid of 3D NCNTs skeleton as the transport channel of the electron, the NiS2/NCNTs exhibit a high capacity of 244.5 mAh g−1 at 50 mA g−1 and an outstanding rate performance (94.7 mAh g−1 at 1000 mA g−1). It achieves capacitance retention of 58% after 2000 cycles at 200 mA g−1. Through theoretical density functional theory (DFT) calculations and a series of systematic ex situ characterizations, the magnesiation/demagnesiation mechanisms of NiS2 and NiS2/NCNTs and are elucidated for fundamental understanding.
