“…Conducting CO 2 -Red in CO 2 -capturing media is another effective strategy. Amines, − hydroxides, − and alkoxides − are well known as effective additives to capture CO 2 molecules in solutions. Ionic liquids (ILs) have been recently reported as effective solvents for CO 2 -Red.…”

Increasing concentration of atmospheric CO 2 is a worldwide concern and continues to trigger various environmental problems. Photo-or electrocatalytic CO 2 reduction (CO 2 -Red) using solar energy, i.e., artificial photosynthesis, is a prospective technique owing to its sustainability and the usefulness of the reaction products. Concentrations of CO 2 in exhaust gases from industries are several % to 20%, and that in the atmosphere is about 400 ppm. Although condensation processes of CO 2 require high energy consumption and cost, pure CO 2 has been used in most of the reported studies for photo-and electrocatalytic CO 2 -Red because the reaction between CO 2 and the catalyst could be one of the rate-limiting steps. To address these issues and provide a repository of potential techniques for other researchers, this perspective summarizes the catalytic systems reported for the reduction of low-concentration CO 2 , which utilize a combination of catalytic CO 2 -Red and CO 2 -capturing reactions (or CO 2 adsorption). First, we describe CO 2 insertions into M−X bonds of the catalysts, which increase the rate constants and/or equilibrium constants for CO 2 binding on the catalysts, and modifications of the second coordination sphere to stabilize the CO 2 -bound catalysts. Furthermore, we discuss the reaction media used for catalytic CO 2 -Red that have the unique effect of increasing CO 2 concentrations around the catalysts. These reaction media include typical CO 2 -capturing additives, ionic liquids, and metal−organic frameworks.

Bimetallic metal-organic framework CuCo-BTC was synthesized via a facile hydrothermal method and then a CuCo-BTC coated Au/multi-wall carbon nanotubes (MWCNTs) electrode (CuCo-BTC/Au/MWCNTs/CF) was prepared on copper foam for glucose sensing. Due to the synergic catalytic effect of Cu and Co, excellent conductivity and large surface area of MWCNTs, and good catalytic property of gold, CuCo-BTC/Au/MWCNTs/CF can provide more effective active sites, so as to improve the charge transports and the electro-catalytic performance. As a result, under optimized conditions, the electrode exhibits a wide linear range of 0.01-5 mM, 5-9 mM, a sensitivity of 1.029 mA·mM-1·cm-2, and a detection limit of 3.4 μM (S/N =3) for glucose detection. Meanwhile, it also demonstrates satisfactory selectivity, reproducibility, and stability. Furthermore, the electrode was successfully applied for the detection of glucose in serum, this work validates the potential of the fabricated sensor for non-enzymatic blood glucose monitoring.

“…To investigate the dependence of the electrochemical activity on the type of tertiary amine, Hosseini et al analysed solutions of monoethanolamine, diethylenetriamine (DETA), diisopropylamine (DIPA), and aminoethylpiperazine (AEP) with and without the addition of bicarbonate using CV. 57 Of these; only DIPA showed a significant catalytic effect on bicarbonate reduction, then the mechanism of carbonate reduction in DIPA was explored electrochemically by scan rate control experiments and EIS analysis.…”
