Selenium heteroatom-doped mesoporous carbon as an efficient air-breathing electrode for rechargeable lithium–oxygen batteries

Abstract

Intentional heteroatom-doped mesoporous carbon was generated from the spent disposable papercups and explored as an air-breathing electrode for rechargeable Lithium-Oxygen (Li-O2) battery. The crystal structure and morphology of each of...

Selenium-doped carbon materials: synthesis and applications for sustainable technologies

“…Se-doped activated carbon prepared from paper cups and Se powder was proposed as a metal-free, bifunctional (ORR/OER) air cathode electrocatalyst for the Li–O 2 battery. 106 The Se-doped catalyst achieved high catalytic activity (KOH solution) as compared with the corresponding B- or N-doped carbons. Interestingly, the Se-doped carbonaceous material contained 7.38% of Se and as much as 35.59% of oxygen (at%, XPS).…”
