“…Bennett and coworkers demonstrated an approach based on a photo-induced pH change by an mPAH. 17 The pH drop reduced the solubility of CO 2 and led to CO 2 release. Although the pH change was small in this preliminary work, this approach is promising since no chemical waste is generated and solar energy could be used in the process.…”

“…As a reversible photoacid, an mPAH has been used to react with a base directly. 17 The base was neutralized by the mPAH under irradiation, and recovered its basicity after the light was turned off. In other words, an mPAH can convert a regular base to a negative photobase, which lowers its basicity under irradiation.…”

Electrocatalytic Ethanol Oxidation on Cobalt–Bismuth Nanoparticle-Decorated Reduced Graphene Oxide (Co–Bi@rGO): Reaction Pathway Investigation toward Direct Ethanol Fuel Cells

Direct ethanol fuel cells (DEFCs) are one of the resourceful and sustainable technologies for energy applications. Ethanol oxidation has been used to construct cost-effective and proficient electrocatalysts to substitute noble-based electrocatalysts like Rh, Pd, Ir, and Ag. Here in, we have presented a surface modification approach of doping a crucial oxophilic character metal onto a transition metal with carbon support. Noble metal-free cobalt−bismuth bimetallic nanoparticledecorated reduced graphene oxide (Co−Bi@rGO) electrocatalysts were fabricated for enhanced ethanol oxidation reaction from their synergetic effect of rGO, Co, and Bi. A highly active, cost-effective, and efficient approach has been developed for the preparation of Co−Bi@rGO (Co NPs; ∼2 nm), initially Bi@rGO (Bi NPs@rGO; ∼50 nm), by a simple reduction method followed by Co, by Galvanic exchange of Bi atoms with Co. The as-synthesized nanocomposites were characterized by transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and BET surface area measurement studies. Cyclic voltammetric studies show an ultralow onset potential of 0.28 V with a high current density of 10.25 mA/cm 2 , having a higher enhancement factor for Co−Bi@rGO compared to other individuals, including Bi NPs, Bi@rGO, and rGO under similar electrolyte conditions, which could be due to their synergetic cooperative interactions at electrified interfaces. Combined results from chronoamperometry (i−t) and electrochemical impedance spectroscopy show that Co−Bi@rGO is highly durable and sensitive toward the ethanol oxidation reaction compared to individual counterparts. This work also provides the noble metal-free bimetallic electrocatalysts for ethanol oxidation and assists in hydrogen production from an agricultural base.

“…Increasing concerns about CO 2 emission issues call for the development of new clean sustainable technologies. Therefore, CO 2 splitting has attracted a great attention over the past years within the fields of environmental sciences (Snoeckx and Bogaerts 2017;Bennett et al 2017). The technologies using solar derived systems and/or cold plasma, without requirement for high pressures and/or temperatures, powering the conversion of CO 2 to chemical fuels are nowadays of decisive importance to address energy and environmental demands.…”

There is still a growing interest in CO 2 conversion into useful compounds. Plasma technology is a highly promising alternative due to its non-equilibrium nature, crucial for CO 2 dissociation processes. In this study we present, the non-thermal plasma-assisted catalytic CO 2 reduction to CO on 2D Zn-containing paddle wheel structures based on TCPP. The catalytic efficiency of this MOF material is shown to be high. The experimental data from HRTEM, adsorption and FTIR analyses lead to the simplified model mechanism of this process.
