Selective electro- or photo-reduction of carbon dioxide to formic acid using a Cu–Zn alloy catalyst

Abstract

A copper-and-zinc (Cu–Zn) alloy material was synthesized using a vacuum sealing method, in which evaporated zinc was reacted with copper film or nanoparticles to form a homogeneous Cu–Zn alloy.

CuSn Alloy Nanoparticles on Nitrogen‐Doped Graphene for Electrocatalytic CO2 Reduction

“…The competitive interaction of H + /water with two metal centers may tune the binding strength of intermediates and control the reaction pathway to accelerate the reaction rate of CO 2 reduction on the surface. A few recipes of alloying have been developed for the synthesis of Cu‐based or Sn‐based electrocatalysts for CO 2 RR, including CuPd, CuPt, CuAu, CuAg, CuIn, CuZn, CuSn, SnAg, SnPd, SnPb, etc. For CuSn bimetallic systems as a kind of potential catalysts, previous research works have shown that the control of their composition provided a promising approach for improving the electrocatalytic properties for CO 2 reduction .…”

A Cu–Zn nanoparticle promoter for selective carbon dioxide reduction and its application in visible-light-active Z-scheme systems using water as an electron donor

“…Besides, the higher TON was recorded to be 1400 in the case of our Cu-Zn/SrTiO 3 under UV irradiation. 18 These results strongly suggest that our Z-scheme system is highly stable under photon irradiation in aqueous media. The quantum efficiency for the reduction products was 0.14% in our system.…”

“…However, highly selected HCOOH generation has only been achieved by using expensive noble metal-complexes to date. 17 In contrast, in our previous research, copper and zinc based bulk alloys were investigated as electrocatalysts for HCOOH production, 18 but they could not be applied in photocatalysis or photo-electrochemical systems because of their bulk form and/or high temperature preparation conditions.…”

“…Although our previous study reported the synthesis of the bulk Cu-Zn electrocatalyst for selective CO 2 reduction, 18 the present study developed the highly dispersed intermetallic Cu-Zn NPs via a wet chemical process and optimized their chemical composition and structure according to the performance of their electrochemical CO 2 reduction (described in the ESI † in detail, Fig. S3 and S4).…”

A Categorical Naked‐Eye Detection of Cu2+ and Zn2+ through a Donor‐Acceptor‐Donor (D‐A‐D)‐Type Salicylaldimine: An Experimental and Theoretical Approach

“…Nevertheless, the higher concentrations of Cu 2+ are reported to be responsible for diseases such as Menkes, Wilson‘s Parkinson's while that of Zn 2+ for ischemia, seizures, and Alzheimer's etc . These two metal ions have also a wide range of applications in the field of chemistry as important constituent of various chemicals including catalysts as well as electrodes . In the light of their wide spectrum applications of Cu 2+ and Zn 2+ , their accurate and easy marking is one of the important tasks for the practitioners of chemistry ranging from academics to industries.…”
