CuBi electrocatalysts modulated to grow on derived copper foam for efficient CO2-to-formate conversion

Electroreduction of CO2: Advances in the Continuous Production of Formic Acid and Formate

“…Although most of the approaches using GDEs compiled in Table have employed carbon fibrous supports, other kind of substrates have also been reported, like carbon cloths, ,, PTFE gas-diffusion substrates, copper hollow fiber supports, metal copper meshes, , or metal copper foams . In particular, tests with cloth substrates required PTFE treatment to prevent cathode flooding, ,, as well as a larger volume of electrolyte to dilute HCOO – and limit crossover .…”

“…On the one hand, the use of Cu hollow fiber as the substrate allowed Rabiee et al to prepare hollow fiber GDEs with free ionomer Bi-based catalysts. GDEs fabricated with other Cu-based substrates, such as meshes , or foams, have also been reported due to their good properties of ductility, electrical conductivity, and low cost.…”

“…Definitions of the figures of merit are explained in Section . The last column shows the icon used to represent each study in the graphical representations of Figures –, according to the symbols and meanings detailed in Table . …”

Recent progress and prospect of electrodeposition-type catalysts in carbon dioxide reduction utilizations

“…CuAg [17,59] , CuSn [60,61,62,28,63] , CuPb [64] , CuIn [47,65,66] , CuPd [67] , CuBi [68] etc. In Figure 10a, Yeo et al proposed a strategy to compensate for the insufficient CO solubility by introducing Cu x Zn alloy to catalyze the in situ generation of CO during the CO 2 RR process [58] .…”

“…At present, most research studies focus on the combination of Cu with another metal to improve the CDRR performance, such as CuZn, 58 CuAg, 17,59 CuSn, 28,[60][61][62][63] CuPb, 64 CuIn, 47,65,66 CuPd, 67 CuBi, 68 etc. In Fig.…”
