Electro-Oxidation Reaction of Methanol over La2–xSrxNiO4+δ Ruddlesden–Popper Oxides

“…In order to achieve a higher current density as well as better MOR activity, a conducting polymer PANI was used as a support of La 1.4 Sr 0.6 NiO 4+δ . − The cyclic voltammograms of the La 1.4 Sr 0.6 NiO 4+δ /PANI composite and unsupported La 1.4 Sr 0.6 NiO 4+δ during MOR in an alkaline medium (0.5 M NaOH and 1.5 M MeOH at 50 mV s –1 scan rate) are provided in Figure d. La 1.4 Sr 0.6 NiO 4+δ /PANI revealed a significant 5-fold increment in oxidative peak current density for MeOH oxidation at 1.59 V versus RHE, with an increased MOR current density of 3.34 mA cm –2 .…”

Composite electrodes with superior catalytic activity in methanol electro-oxidation fabricated using ternary NiO–CuO–ZnO mixed metal oxides

“…17 Among all other types of available fuel cells, alcoholic fuel cells have garnered significant research attention because of their higher energy density, eco-friendliness, better performance, and low operating temperatures. 18 Furthermore, in alcoholic fuel cells, the difficulties produced by the storage and conversion of hydrogen in fuel cells have been resolved. 19 Hence, due to these features, alcoholic fuel cells have been preferred by researchers to other fuel cells.…”

Layer-by-Layer Assembly of CTAB-rGO-Modified MXene Hybrid Films as Multifunctional Electrodes for Hydrogen Evolution and Oxygen Evolution Reactions, Supercapacitors, and DMFC Applications

“…The world’s current energy crisis is caused by the never-ceasing depletion of the oil resources and the deterioration of the ecological environment primarily due to carbon dioxide-emitting fossil fuels and has encouraged scientists to research green energy and renewable sources. − Numerous businesses have shifted focus on the automotive market to lessen the world’s reliance on petroleum resources, including big names like Honda, Mercedes-Benz, Hyundai, and Tesla, to emphasize the usage of hybrid materials for fuel cells and electric motors using green energy. , Issues concerning global warming, pollution, and a suitable energy alternative that could replace non-renewable energy and equip the ever-growing population have resulted in more attention being placed on electrochemical energy applications like supercapacitors, − fuel cells, , and electrochemical water splitting, , thanks to their environmental friendliness, good cyclic stability, and high power density. The high power density of the supercapacitors and the minimal operating temperatures of the fuel cells like the proton exchange membrane fuel cells, alkaline electrolyzers, and direct methanol fuel cells (DMFCs) could effectively produce clean and green energy .…”
