“…Methanol was chosen in view of its high solubility factor for the CO 2 analyte, which is 5 times more than water. 55 Later, the sample was withdrawn to know about the nature of the product. As seen from the graphs, TBAB in DMF gave a higher concentration of formic acid, viz., 66.57 mM, but there was no trace of the formation of acetic acid.…”

A recent class of porous materials, viz., metal–organic frameworks (MOFs), finds applications in several areas. In this work, Cu-based MOFs (Cu–benzene-1,3,5-tricarboxylic acid) along with graphene oxide, viz., Cu-MOF/GO, are synthesized and used further for reducing CO 2 electrochemically. The reduction was accomplished in various supporting electrolytes, viz., KHCO 3 /H 2 O, tetrabutylammonium bromide (TBAB)/dimethylformamide (DMF), KBr/CH 3 OH, CH 3 COOK/CH 3 OH, TBAB/CH 3 OH, and tetrabutylammonium perchlorate (TBAP)/CH 3 OH to know their effect on product formation. The electrode fabricated with the synthesized material was used for testing the electroreduction of CO 2 at various polarization potentials. The electrochemical reduction of CO 2 is carried out via the polarization technique within the experimented potential regime vs saturated calomel electrode (SCE). Ion chromatography was employed for the analysis of the produced products in the electrolyte, and the results showed that HCOOH was the main product formed through reduction. The highest concentrations of HCOOH formed for different electrolytes are 0.1404 mM (−0.1 V), 66.57 mM (−0.6 V), 0.2690 mM (−0.5 V), 0.2390 mM (−0.5 V), 0.7784 mM (−0.4 V), and 0.3050 mM (−0.45 V) in various supporting electrolyte systems, viz., KHCO 3 /H 2 O, TBAB/DMF, KBr/CH 3 OH, CH 3 COOK/CH 3 OH, TBAB/CH 3 OH, and TBAP/CH 3 OH, respectively. The developed catalyst accomplished a significant efficiency in the conversion and reduction of CO 2 . A high faradic efficiency of 58% was obtained with 0.1 M TBAB/DMF electrolyte, whereas for Cu-MOF alone, the efficiency was 38%. Thus, the work is carried out using a cost-effective catalyst for the conversion of CO 2 to formic acid than using the commercial electrodes. The synergistic effect of GO sheets at 3 wt % concentration and Cu + OH – interaction leads to the formation of formic acid in various electrolytes.

“…Then 5.0 μL of this dispersed suspension was drop casted on GC electrode and dried under ambient conditions. Nafion acts as a binding agent and therefore helps in better adherence of Cu MOF on GC surface which consequently increases the stability of the prepared electrode surface [38][39]. The electrochemical behaviour of Cu MOF modified GC was studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in PBS solution (0.1 M, pH 8.0).…”

The electrochemical detection of ciprofloxacin (CIP) using copper metal organic framework (Cu BTC) is reported. The glassy carbon electrode was used as a base electrode which was further modified with Cu BTC and differential pulse voltammetry technique was adopted for electrosensing. Under optimized conditions, a linear response for CIP was obtained in concentration range from 1×10−8 to 20×10−6 mol L−1 with a limit of detection of 0.47×10−9 mol L−1. Moreover, the proposed electrosensor showed acceptable reproducibility with 2.39 % relative standard deviation. Determination of CIP in tap water samples showed good recovery in range of 94.6–108 %.

“…This strategy can effectively mitigate this issue, e.g dopping different amount of Ru into Pt promote water oxidation near methanol oxidation potential, liberate OH ads species tuning CO to CO 2 with minimized Pt poisining. [8][9][10][11][12] Another reason for platinum inactivation is Ptelectrode deactivation under harsh conditions (acidic media) due to deposition of metals present as impurity in an electolyte during the analysis. Above mentioned problem can be resolved by in-situ reactivation process, where the polarity of electrolyte would be switched off (orginal polarity retained) and deposited impurities(metals) would be flushed out by the anodic oxidation in case of reduction process and vice versa for a sufficient time period under optimized conditions (temperature, current density etc) to prevent degradation and dissolution of electrocatalyst.…”

“…Cu-BTC/5 wt % GO composite with current density of 120 mA cm À 2 at scan rate of 50 mV s À 1 claimed to be a promising alternate for expensive Pt based materials. [8] The methanol oxidation tendency of bimetallic NiÀ Co/ graphene composites prepared by varying Ni/Co ratio was studied by Sarwar and coworkers in 2017.

In this research, electrocatalytic activity of cobalt benzene tricarboxylic acid metal organic framework (Co BTC MOF) and its reduced graphene oxide based composites (rGO/Co BTC) were investigated in an alkaline media for the methanol oxidation reaction (MOR). Metal Organic frameworks (MOF) and their composites were solvothermally prepared and characterized via FTIR, EDX, SEM and XRD. Electrochemical studies were performed by cyclic voltammetry, electron impedance spectroscopy, chronoamperometry and cyclic stability. Among all the prepared composites, 1 wt % rGO/Co BTC MOF (1.07 mg cm À 2 ) demonstrated a promising current density of 130 mA cm À 2 at 1.59 V vs. RHE, a tafel slope of 83.6 mV dec À 1 and resistance of 14.75 Ω in 1 M NaOH/ 2 M methanol solution showing much better performance than state-of-the-art Pt based materials.[a] L.
