MoP Nanoparticles Supported on Indium‐Doped Porous Carbon: Outstanding Catalysts for Highly Efficient CO₂ Electroreduction

Abstract

Electrochemical reduction of CO into value-added product is an interesting area. MoP nanoparticles supported on porous carbon were synthesized using metal-organic frameworks as the carbon precursor, and initial work on CO electroreduction using the MoP-based catalyst were carried out. It was discovered that MoP nanoparticles supported on In-doped porous carbon had outstanding performance for CO reduction to formic acid. The Faradaic efficiency and current density could reach 96.5 % and 43.8 mA cm , respectively, when using ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate as the supporting electrolyte. The current density is higher than those reported up to date with very high Faradaic efficiency. The MoP nanoparticles and the doped In O cooperated very well in catalyzing the CO electroreduction.

Multifunctional Transition Metal‐Based Phosphides in Energy‐Related Electrocatalysis

“…Similar to binary alloys, transition metal phosphides may be qualified to be CO 2 RR electrocatalysts due to their multifunctional active sites and good electrical conductivity. This hypothesis was firstly proved by Han's group . They prepared the MoP nanoparticles supported on indium‐doped porous carbon and demonstrated their application in electrochemical CO 2 reduction ( Figure 16 a).…”

“…Therefore, in most cases, the potential roles of TMPs in electrocatalytic CO 2 RR are ignored. In 2018, Han and co‐workers first investigated the CO 2 RR activity on metal phosphide under a nonaqueous solution . With using the ionic liquid as supporting electrolyte, MoP/In‐doped porous carbon composites can effectively facilitate the electroreduction of CO 2 into formic acid with a record‐breaking faradaic efficiency and current density.…”

“…[1] The conversion of CO 2 into valuable chemicals is one of the most promising pathways to reduce CO 2 emission and fully utilize this abundant, cheap, and nontoxic C 1 source. [4][5][6] In particular, the cycloaddition of epoxidesw ith CO 2 to form cyclic carbonates is an important and atom-economic reaction, and the resultant products are important heterocyclic compounds widely used in organic synthesis.

Highly Efficient Electroreduction of CO2 to Methanol on Palladium–Copper Bimetallic Aerogels

“…

Electrochemical reduction of CO 2 to CH 3 OH is of great interest. [2][3][4][5][6][7] In particular, numerous efforts have been dedicated to developing and improving the performance of metal catalysts for CO 2 RR, [8,9] among which controlling the size,s hape,a nd morphology of nanostructured metals is an effective strategy. The current density and Faradaic efficiency of CH 3 OH can be as high as 31.8 mA cm À2 and 80.0 %o ver the Pd 83 Cu 17 aerogel at av ery low overpotential (0.24 V).
