The reduction reaction of carbon dioxide on a precise number of Fe atoms anchored on two-dimensional biphenylene

Abstract

In a recent accomplishment, a new two-dimensional allotrope of carbon-biphenylene (BP) was experimentally synthesized [Fan et al., Science, 372, 852-856 (2021)]. The BP sheet is composed of four-, six-, and...

Transition metal small clusters anchored on biphenylene for effective electrocatalytic nitrogen reduction

“…43 Then, extensive studies have been carried out to reveal the unique physical and chemical properties of this novel graphene-like carbon material. [44][45][46][47][48] With regular distributed four-, six-, eightmembered ''holes'' and very active atoms and chemical bonds, 2D BPN sheets are expected to exhibit an improved performance as a potential anchoring material. However, although several studies have demonstrated that the pure BPN monolayer possesses superior HER, 44 OER, 46 CO 2 RR, 47 and methane oxidation reaction activities, 48 a systematic analysis of the NRR mechanisms upon the decoration of this novel 2D material with small transition metal clusters is still worthy to be discovered.…”

B−N Co‐Doped Biphenylene as a Metal‐Free Cathode Catalyst for Li−O2 Batteries: a Computational Study

“…The C atoms on the 4‐membered ring of biphenylene can facilitate the activation of O 2 ; hence, biphenylene exhibits an excellent oxygen reduction reaction (ORR) performance [25] . Furthermore, introducing heteroatoms can influence biphenylene‘s electronic, magnetic, and catalytic properties, which leads to the enhanced catalytic activity of heteroatom‐doped biphenylene for ORR, hydrogen evolution reaction, and CO 2 reduction [26–29] . This situation inspired us to explore the catalytic performance of biphenylene and its doped structures as cathode catalysts for LOBs.…”

Possible Superconductivity in Biphenylene

“…Biphenylene also demonstrates excellent catalytic properties due to its good metallic properties. For instance, it can be used in hydrogen evolution reaction with atomic doping, [14,15] CO2 reduction reaction with Fe atoms doping, [16] and electrochemical nitrogen reduction reaction with Mo atoms doping. [17] Furthermore, it can be applied in superlattice nanostructures to achieve lower thermal conductivity for nanodevices.…”
