“…TAR formation comes from the subsequent oxidation of the glycerate (GLCA) anion, which in turn comes from GLAD oxidation. This chemical route justifies the low GLAD concentrations detected. − The low TAR concentrations of about 10 mg·L –1 (Figure a) and the eight electrons involved in the corresponding oxidation reaction give rise to FE toward this product of about 2% (Table S4). Another chemical route for further oxidation of the GLAD intermediate involves the production of glycolate (GLYC) from the GLCA anion.…”

CO 2 electroreduction has emerged as a promising strategy for reducing emissions while simultaneously generating valuable products, particularly formic acid/formate. To further enhance the sustainability of this process, the traditional oxygen evolution reaction at the anode can be replaced by a more interesting reaction like glycerol oxidation to high value-added products, in a covalorization approach. In this study, the effect of the presence of a bismuth (Bi) atom supplier (Bi 2 O 3 particles) in the anolyte solution during the glycerol electrooxidation process on platinum (Pt) electrodes coupled with the electroreduction of CO 2 to formate is investigated for the first time, operating in a continuous mode with a single pass through the reactor. The results reveal that in the cathode, significant HCOO − production, with Faradaic efficiencies reaching 93%, and modest energy consumption of 208 kW h•kmol −1 were obtained in the continuous CO 2 electroreduction to formate using Bi gas diffusion electrodes. On the other hand, in the anode, the presence of Bi 2 O 3 particles leads to a significant alteration in the distribution of high-value-added oxidation products obtained. For instance, the anode demonstrates remarkable dihydroxyacetone (DHA) production of 283 μmol•m −2 •s −1 , surpassing the results obtained with the nonmodified Pt electrodes. The performance of this system offers a promising pathway for the simultaneous coproduction of high-value-added products from both CO 2 and glycerol.

Electrocatalytic and Photoelectrocatalytic Sensors Based on Organic, Inorganic, and Hybrid Materials: A Review

Electrochemical sensors present a wide range of interesting applications in the areas of environmental, industrial, and chemical analysis. This review presents an overview of two types of sensors: electrocatalytic ones, which involve oxidation and reduction reactions through electron transfer, and photoelectrocatalytic ones, which involve a current response due to the incidence of light and redox reactions. Another point discussed was how these sensors’ detection capacity and behavior can be affected by several factors related to the material used to make the electrode. In this way, inorganic, organic, and hybrid materials were compared in electrocatalytic and photoelectrocatalytic sensors. The use of inorganic materials is interesting due to the fact of their abundance, low cost, and good electroactivity. Among organics, conductive polymers and carbonaceous materials are often cited due to the fact of their conductivity and their different possibilities for synthesis, being possible to mold their shape. Finally, hybrid materials unite these two classes, presenting different properties not found in a single substance.

“…Theoretically, a standard thermodynamic potential of 1.23 V is required for the cell voltage in both acidic and alkaline electrolytes, while real electrolyzers still need to operate at higher voltages to work effectively. [55][56][57][58] Also, the corresponding reactions (1)-( 4) are included as follows:…”
