![]() And hence, the desire to advance the CO 2 utilization technologies such as electrochemical CO 2 reduction (CO 2R) at ambient temperatures and pressures which has a strong passion towards saving the world from the existing global warming is becoming accustomed. Various strategies have been developed to reduce the accumulated CO 2 in the atmosphere. Carbon dioxide (CO 2) is the major greenhouse gas that largely contributes to global warming. It has been a great deal of attention in the scientific community to find clean and sustainable energy source in order to circumvent the climate change. The ignition of fossil fuels for energy use emits huge amount of pollutant gases, like carbon dioxides. The advancement of feasible and sustainable energy is an unavoidable issue for researchers due to the harmful effect of fossil fuels on the environment. Consequently, the reaction occurred on the working electrode can be influenced by the number of protons coming from the anode. ![]() ![]() The protons (H+) obtained from the oxidation of H2O onto these three different anodic materials (platinum, glassy carbon, hematite) are moving faster through the bulk of the solution to the working electrode. Similar activity and selectivity to CO formation were observed when platinum and hematite were used as counter electrodes, while the least CO formation was recorded on the glassy carbon counter electrode. In the meantime, x-ray diffraction is used to investigate the crystal planes of the as-prepared electrodes, while the work function and morphology of Au films were measured by atomic force microscope. Linear sweep voltammetry and electrochemical impedance spectroscopy have been used to study electrocatalytic properties. Therefore, the present study aimed to investigate the impact of three different anode materials (platinum, glassy carbon, and hematite) on the activity and selectivity of the gold cathode in an electrochemical CO 2 reduction reaction. ![]() Although H 2O oxidation near-neutral solution does not being received greater attention, there is also an idea that it plays an important role not only in completing CO 2 reduction cycle, but also to significantly influence the cathode during reduction. We believed that CO 2RR performance can be influenced by the anode materials employed for the oxidation half-reaction. CO 2RR to value-added products is an indispensable option to address climate change and energy storage needs. Electrochemical carbon dioxide reduction reaction (CO 2RR) has been investigated for decades. ![]()
