The reduction of CO2 on polyaniline electrode in a membrane cell

Reduction of CO2 under high pressure and high temperature on Pb-granule electrodes in a fixed-bed reactor in aqueous medium

“…In all other cases, the H 2 -evolution is promoted. In fact, comparable behaviours had also been observed during the CO 2 reduction in our previous studies on conducting polymer electrodes [19][20][21][22][23]. The results obtained on Pb granule electrodes in the fixed-bed reactor at different high-pressure values are presented in Table 1.…”

“…For the reduction of CO 2 , most of the metals in the periodic table of the elements [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and synthetic metals (conducting polymers) such as polyaniline and polypyrrole [19][20][21][22][23][24] have been used as electrode material in different electrolytes and in various electrochemical cells. Most of the cited works here have been done in H-cells with metal plate electrodes.…”

Microstructural surface changes of electrodeposited Pb on gas diffusion electrode during electroreduction of gas‐phase CO2

“…[8] The reduction process necessitates the use of specific metal catalysts due to their product selectivity. [1] Electrode materials other than metals, especially polymers such as polypyrrole [7] and polyaniline, [9] have been applied successfully during CO 2 reduction and have been shown to be responsible for product selectivity. However, a variety of metals have different reactivities and stabilities and hence their catalytic activities may be affected by reduction media, size and shape of catalyst or prevailing conditions that can lead to their inactivation or changes in form or morphologies.…”

Photo- and Electro-Catalysis

“…82 Conductor-polymer electrodes such as polyaniline electrode have been used in heterogeneous electrocatalytic CO 2 reduction. 83 The maximum faradaic efficiency of CO 2 electrochemical reduction reported for this electrode is 78% for acetic acid and 12% for formic acid in methanol solution. Aromatic amines, such as pyridinium cation and its substituted derivatives, have been used as homogeneous electrocatalysts for the reduction of CO 2 .…”
