LITHIUM-BROMINE EXCHANGE REACTION ON C60: FIRST THEORETICAL PROPOSAL OF STABLE SINGLET FULLERENE CARBENE WITHOUT HETEROATOM

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 25 gennaio 2021 Up to now, all of the stable singlet carbenes consist of center carbon atom, donor- or withdrew-electron substituents with heteroatoms, for instance, N, P, O, and S. Herein, carbene, generated by lithium-bromine exchange reaction, was used to functionalize C60. The reaction......

SELF-TEMPLATED FORMATION OF HIERARCHICALLY YOLK-SHELL-STRUCTURED ZNS/NC DODECAHEDRA WITH SUPERIOR LITHIUM STORAGE PROPERTIES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 24 dicembre 2020 The hierarchical ZnS/NC dodecahedra are successfully constructed via a two-step synthetic method combining a sulfidation process and subsequent carbonization treatment, benefiting from the inherit merits of zeolitic imidazolate frameworks as ideal precursors/self-sacrificing templates. Studies reveal that the sulfidation time plays a......
