“…Besides pure metals, alloying of two different metals is explored so as to tune the binding strength of key intermediates through geometric and electronic effects, and therefore optimize the CO 2 RR reaction activity and selectivity. Thus far, most research attention has been focused on Cu‐based alloys, such as Cu–Au, Cu–Pd, Cu–In and Cu–Pt and Cu–Sn, and some showed very exciting results 92, 93, 94, 95, 96. It can be reasonably expected that the alloying strategy would soon be expanded to other combination for better possibilities.…”

Increasing CO2 concentration in the atmosphere is believed to have a profound impact on the global climate. To reverse the impact would necessitate not only curbing the reliance on fossil fuels but also developing effective strategies capture and utilize CO2 from the atmosphere. Among several available strategies, CO2 reduction via the electrochemical or photochemical approach is particularly attractive since the required energy input can be potentially supplied from renewable sources such as solar energy. In this Review, an overview on these two different but inherently connected approaches is provided and recent progress on the development, engineering, and understanding of CO2 reduction electrocatalysts and photocatalysts is summarized. First, the basic principles that govern electrocatalytic or photocatalytic CO2 reduction and their important performance metrics are discussed. Then, a detailed discussion on different CO2 reduction electrocatalysts and photocatalysts as well as their generally designing strategies is provided. At the end of this Review, perspectives on the opportunities and possible directions for future development of this field are presented.

“…[1][2][3] Motivated by this objective, numerous publications have appeared in recent years aimed at identifying electrocatalysts that can efficiently and selectively reduce CO 2 to desired products. [4][5][6][7][8][9][10] However, objective evaluation of the activity and selectivity of different catalysts and operating conditions has proven difficult due to a lack of standardized protocols for preparing catalysts and evaluating their electrocatalytic activity. These issues are significant because the performance of electrocatalyts is influenced not only by the composition and morphology of the electrocatalyst itself, but also by the composition of the electrolyte, the hydrodynamics of the electrochemical cell, and the purity of both the electrocatalyst and the electrolyte.…”

Objective evaluation of the performance of electrocatalysts for CO 2 reduction has been complicated by a lack of standardized methods for measuring and reporting activity data. In this perspective, we advocate that standardizing these practices can aid in advancing research efforts toward the development of efficient and selective CO 2 reduction electrocatalysts. Using information taken from experimental studies, we identify variables that influence the measured performance of CO 2 reduction electrocatalysts and propose procedures to improve the accuracy and reproducibility of reported data. We recommend that catalysts be measured under conditions which do not introduce artifacts from impurities, either from the electrolyte or counter electrode, and advocate the acquisition of data measured in the absence of mass transport effects.Furthermore, measured rates of electrochemical reactions should be normalized to both the geometric electrode area as well as the electrochemically active surface area to facilitate the comparison of reported catalysts with those previously known. We demonstrate that when these factors are accounted for, the CO 2 reduction activity of Ag and Cu measured in different laboratories exhibit little difference. Adoption of the recommendations presented in this perspective would greatly facilitate the identification of superior catalysts for CO 2 reduction arising solely from changes in their composition and pretreatment.
