Dual active sites fabricated through atomic layer deposition of TiO₂ on MoS₂ nanosheet arrays for highly efficient electroreduction of CO₂ to ethanol

Abstract

Electrochemical reduction of CO2 to ethanol through renewable electricity is highly desirable but still challenging. Here, we demonstrated that TiO2/MoS2 nanosheet arrays synthesized through atomic layer deposition (ALD) of TiO2...

High Efficient Catalyst of N‐doped Carbon Modified Copper Containing Rich Cu−N−C Active Sites for Electrocatalytic CO2 Reduction

“…Since there is no CH x in the electroreduction products, but a certain amount of CO is present, it is suggested that the formation of ethanol probably goes through a CO−CO coupling reaction process. The possible formation process of ethanol is as follows: CO 2 →*CO 2 →*COOH→*CO→*CO+*CO→*OCCO→*OCCHO→*COHCHO→*CCHO→*CHCHO→*CH 2 CHO→*CH 2 CHOH→*CH 3 CHOH→*CH 3 CH 2 OH [38] …”

Recent progress of dual-site catalysts in emerging electrocatalysis: a review

“…in CO 2 RR due to the synergistic effect of the multiple active sites, thus improving their tandem reaction efficiency. 161–163…”

Recent advances in MoS2-based materials for electrocatalysis

“…The catalyst also showed robust durability. Qi et al 213 fabricated TiO 2 /MoS 2 nanosheets to convert CO 2 into ethanol. Decorating MoS 2 with TiO 2 did not change the original morphology of the MoS 2 material but resulted in more exposed active sites due to the neat distribution of TiO 2 on the surface of MoS 2 .…”
