Cu‐Based Organic‐Inorganic Composite Materials for Electrochemical CO₂Reduction

Abstract

Electrochemical CO2 reduction reaction (CO2RR) is an attractive pathway to convert CO2 into value‐added chemicals and fuels. Copper (Cu) is the most effective monometallic catalyst for converting CO2 into multi‐carbon products, but suffers from high overpotentials and poor selectivity. Therefore, it is essential to design efficient Cu‐based catalyst to improve the selectivity of specific products. Due to the combination of advantages of organic and inorganic composite materials, organic‐inorganic composites exhibit high catalytic performance towards CO2RR, and have been extensively studied. In this review, the research advances of various Cu‐based organic‐inorganic composite materials in CO2RR, i. e., organic molecular modified‐metal Cu composites, Cu‐based molecular catalyst/carbon carrier composites, Cu‐based metal organic framework (MOF) composites, and Cu‐based covalent organic framework (COF) composites are systematically summarized. Particularly, the synthesis strategies of Cu‐based composites, structure‐performance relationship, and catalytic mechanisms are discussed. Finally, the opportunities and challenges of Cu‐based organic‐inorganic composite materials in CO2RR are proposed.

Recent developments in ionophore-based potentiometric electrochemical sensors for oceanic carbonate detection

“…209 Recently, a new clean strategy to reduce greenhouse gas emissions by transforming atmospheric CO 2 into useable chemicals and fuels may become the driving force towards carbon neutrality. 209–212 The large-scale implementation of ocean-based carbon dioxide removal (CDR) technologies coupled with this new promising strategy to reduce CO 2 emission has enormous potential to mitigate climate change and prevent further ocean acidification.…”

Recent advances in copper-based catalysts for electrocatalytic CO 2 reduction toward multi-carbon products

“…For instance, as one of the most common reactions in thermal catalysis, typical conditions for methanol synthesis using CO 2 are at 100 bar and 250 °C [23]. The low number of active sites on the photocatalytic material surface makes it difficult to efficiently adsorb and activate stable CO 2 molecules, resulting in actual photocatalytic CO 2 reduction efficiencies well below the standards of commercialization, accompanied with product yields at μmol•g -1 •h -1 level [24][25][26].

Cu-MOF-74-Derived CuO-400 Material for CO2 Electroreduction

“…This type of material is also frequently used in the modification of Cu-based catalysts. Among these, Cu-MOFs and their derivative catalytic materials have played a significant role in CO 2 RR reactions [24,25]. Research has found that Cu-MOFs and their derivatives exhibit an excellent selectivity and high performance for C2 products.…”
