Mao, Jiayi;Niu, Dechao;Huang, Gaoxu;Jin, Xiaopan;Wei, Chi;Cai, Jia;Li, Yongsheng;Shi, Jianlin research published 《 A Ni/Ni2P heterostructure in modified porous carbon separator for boosting polysulfide catalytic conversion》, the research content is summarized as follows. The intrinsic sluggish conversion kinetics and severe shuttle effect in lithium-sulfur (Li-S) batteries are responsible for their poor reversible capacity and cycling longevity, which have greatly hindered their practical applications. To address these drawbacks, herein, we design and construct a heterostructured Ni/Ni2P embedded in a mesoporous carbon nanosphere composite (Ni/Ni2P-MCN) for boosting polysulfide catalytic conversion in Li-S batteries. The Ni/Ni2P-MCN-modified separator could not only prevent the shuttle effect significantly through abundant chem. adsorptive sites, but also demonstrate superior catalytic reactivities for the conversion of polysulfides. More importantly, the conductive carbon matrix with an exposed mesoporous structure can serve as an effective phys. barrier to accommodate deposited insoluble Li2S. Consequently, the cells with the Ni/Ni2P-MCN-modified separator exhibit greatly boosted rate capability (431 mA h g-1 at 5 C) and cycling stability (a capacity decay of 0.031% per cycle after 1500 cycles). Even at an enhanced sulfur loading of 4.2 mg cm-2, a stable and superior areal capacity (about 3.5 mA h cm-2) has been demonstrated. We envision that the unique Ni/Ni2P heterostructure in the porous carbon matrix could offer great potential for high-performance and sustained energy storage devices.

Methyl 2-bromopropionate is used in the synthesis of poly(ADP-Ribose)polymerase inhibitors derived from benzoxazin-3-one. Also used in the synthesis of 5-HT2C antagonists affecting serotonin levels.
Methyl 2-bromopropanoate is a chemical compound that can be synthesized in an asymmetric manner. The reaction of methyl 2-bromopropanoate with hydrochloric acid gives the corresponding carboxylic acid, methyl propanoate, and hydrogen bromide in a 1:1 ratio. It has been shown that methyl 2-bromopropanoate is a potential catalyst for the reduction of chloride to chloride ion via the borohydride reduction method. Methyl 2-bromopropanoate has also been used as a model system for studying halides and copper complexes. Magnetic resonance spectroscopy studies have revealed that this chemical compound has a high redox potential and kinetic properties., 5445-17-0.
