Considering the rapidly increasing population, development of new resources, skills, and devices that can provide safe potable water clean energy remains one vital research topics for scientific community.
Electrochemical carbon monoxide reduction (COR) is an important link between the electrochemical CO2-to-CO and renewable production of C2+ chemicals. Along with development catalyst materials for selective efficient COR, it imperative to optimize electrolysis conditions cell parameters efficiently reduce CO at industrially relevant current density produce concentrated product streams. This study focuses on understanding fundamental differences in reaction selectivity during when same Cu was...
Producing hydrogen from water in an efficient manner could significantly reduce consumption of fossil fuels. In this regard the abundant presence oceans offers important alternative approach for splitting using seawater. Direct use seawater generation is a difficult and complex process due to various ions seawater, which affect activity catalysts makes selectivity towards challenging task. Herein ways are reported efficiently under visible light irradiation by already group. A better...
Rhombohedral nickel sulfide thin films were deposited on c-sapphire substrate via the atomic layer deposition (ALD) method using acetylacetonate [Ni(acac)2] as and H2S gas sulfur precursors. The self-limiting nature of ALD process is obtained in temperature range 200–240 °C, which provides crystalline NiS without further annealing. A growth rate ∼0.2 Å/cycle was observed at 200 °C. As-deposited studied for non-enzymatic electrochemical glucose sensing. exhibit an excellent sensitivity 5.78...
Abstract This study demonstrates the electrochemical reduction of carbon monoxide (COR) at high current densities in a zero‐gap electrolyzer cell and stack. By systematically optimizing both commercially available membrane electrode assembly components (including binder content gas diffusion layer) operating conditions, we could perform COR up to 1.4 A cm −2 with maximum C 2+ selectivity 90%. We demonstrated scale‐up 3 × 100 2 stack that can sustain stable operation 1 for several hours...
