Electrocatalytic reduction of CO₂ by two-dimensional transition metal porphyrin sheets

Abstract

The first transition metal series TM–PP monolayer catalysts exhibit excellent catalytic performance during the process of electroreduction of CO2. The products have 2e− CO (Sc, Mn and Ni), HCOOH (Cr, Fe, Co, Cu and Zn), 8e− CH4 (Ti and V), and the overpotential of the reaction can be as low as 0.127 V.

Efficient electrocatalytic reduction of carbon dioxide by metal-doped β12-borophene monolayers

“…[7][8][9][10][11][12] Due to their high specic surface area, reduced dimensionality and exotic properties, two-dimensional (2D) nanosheets have become an ideal platform for the design of novel electrocatalysts for CO 2 reduction. [13][14][15][16] Borophene is a novel 2D material under active investigation with fascinating and diverse properties and potential. 17 Recently, honeycomb borophene has been experimentally fabricated on an Al(111) substrate.…”

A new class of organoplatinum-based DFNS for the production of cyclic carbonates from olefins and CO2

“…18,19 Due to their high specic surface area, reduced dimensionality and remarkable properties, two-dimensional (2D) nanosheets have become an ideal platform for the design of novel electrocatalysts for CO 2 reduction. [20][21][22][23][24][25][26][27] Borophene is a novel 2D material under active investigation due to its fascinating and diverse properties and potential. 28 The properties of borophene can be enhanced and extended by alloying with other elements.…”

Environmentally friendly nanocrystalline magnesium hydride decorated with metallic glassy-zirconium palladium nanopowders for fuel cell applications

“…[2][3][4] Accordingly, huge amounts of carbon dioxide and other harmful air pollutants, such as SO 2 and NO x , are emitted upon the burning of fossil fuels for power generation. 5 Recently, it has been pointed out by different authors that two dimensional materials, such as AlB 6 , 6 Cu 2 Si, 7 transition metal-phthalocyanine (TM-Pc) monolayers, 8 single atom catalyst TM-TCNQ monolayers, 9 transition metal porphyrin sheets, 10 and Mn-graphene single-atom, 11 have the potential capacity to catalytically remove gas molecules, such as CO 2 , SO 2 and NO x , or transform them to other species. Among different sources of new/renewable energy options, hydrogen energy carriers have been receiving great attention due to their attractive and unique properties.…”

“…Unfortunately, the classic methods proposed for the storage of hydrogen in its gaseous and liquid states show serious drawbacks due to their high cost and safety issues. In contrast, the solid-state hydrogen storage approach, using for example magnesium (Mg) metal as a storage material shows promising practical solutions 10,11 due to its reliability, safety and cost effectiveness. Accordingly, Mg, its alloys and compounds have been attracting many researchers in both developed and advanced countries.…”
