The electrocatalytic reduction of carbon dioxide (CO2RR) is a crucial technology to develop the decarbonisation strategy for circularity and producing solar fuels substituting fossil fuels. This viewpoint discusses role electrode reactor design as main factor in determining performance CO2RR, at least under reaction conditions relevant industrial scalability, evidencing need overturn current st...

This study investigated the influence of experimental factors on the electrochemical cyanide destruction efficiency in a flow-through reactor using response surface methodology. Central composite experimental design was used to obtain the four main operating factors, such as current density, initial cyanide concentration, chloride concentration, and electrolysis time, on the response surface of...

The electrochemical cathodic reduction of cyclic imides (maleimides) to succinimides can be achieved chemoselectively in the presence of alkene, alkyne, and benzyl groups. The efficiency of the system was demonstrated by using a 3D electrode in a continuous flow reactor. The reduction of 3,4-dimethylmaleimides to the corresponding succinimides proceeds with a 3:2 diastereomeric ratio, which is ...

Microbial electrosynthesis is a useful form of technology for the renewable production of organic commodities from biologically catalyzed reduction of CO₂. However, for the technology to become applicable, process selectivity, stability and efficiency need strong improvement. Here we report on the effect of different electrochemical control modes (potentiostatic/galvanostatic) on both the start...

EXTENDED ABSTRACT Spent pickling baths coming from the hot dip galvanizing process represents an environmental problem due to high ZnCl2, FeCl2 and HCl (among other substances) concentrations. This problem, together with the decrease of natural reserves of nonferrous metals, makes zinc electrowinning coming from spent pickling solutions an interesting alternative. Moreover, membranes, or other ...

The near-unlimited availability of CO2 has stimulated a growing research effort in creating value-added products from this greenhouse gas. This paper presents the trends on the most important methods used in the electrochemical synthesis of carboxylic acids from carbon dioxide. An overview is given of different substrate groups which form carboxylic acids upon CO2 fixation, including mechanisti...

Hydrogen is the preferred fuel for fuel cells due to high reactivity for electrochemical reaction at anode. In the present study, a three dimensional CFD (Computational Fluid Dynamics) code was developed and validated to simulate the performance of a catalytic monolith fuel processor used for hydrogen generation. Methane autothermal reforming on 5% Ru/ -Al2O3 catalyst was selected as the reacti...
