Herein we report the electrocatalytic activity of boron-doped graphene for the reduction of CO2. Electrolysis takes place at low overpotentials leading exclusively to formate as the product (vis-à-vis benchmark Bi catalyst). Computational studies reveal mechanistic details of CO2 adsorption and subsequent conversion to formic acid/formate.

A microporous and polymeric C3N4 framework (CNF), when exploited as an interlayer and as a cathode host in Li–S batteries, demonstrates significantly improved electrochemical behavior with a special relevance to high rate applications up to 5C.
