2021Whenever we think about life sustainability, the most crucial thing that comes first in our mind is oxygen. In the current scenario, oxygen production has grown tremendously due to its increasing demand from health sectors: the complexity, availability, and high cost of oxygen taken as a drawback. So, the development of an efficient, durable, and cost-effective oxygen production technology is necessary. Oxygen evolution reaction (OER) is the process of generating molecular oxygen via a chemical reaction. Scientists now a days focus more on OER-based methods for portable device fabrication to generate breathable oxygen due to its economic and eco-friendly properties. In this article, we demonstrated the simple design and fabrication of an electrochemical-based oxygen evolution setup. The setup involves a plastic jar of (5 Litre) containing 1 M sodium hydroxide (NaOH) aqueous solution, and at the top portion, two holes were created for the immersion of the stainless-steel rod cathode and an anode electrode, which were connected to the power supply. The oxygen generation started in the bubbles form on the supply of voltage of 13V and 9.5A current. The produced oxygen is collected through the plastic tube. It also gives hydrogen, which can be separately stored. At the initial stage, the rate of oxygen production was 2.0 liter/min.

通过高效的电化学过程产生氧气

2021每当我们想到生命的可持续性时，首先想到的最关键的就是氧气。在当前情况下，由于卫生部门对氧气的需求不断增加，氧气产量大幅增长：氧气的复杂性、可用性和高成本被视为缺点。因此，有必要开发一种高效、耐用且具有成本效益的制氧技术。析氧反应 (OER) 是通过化学反应生成分子氧的过程。由于其经济和环保的特性，科学家们现在更多地关注基于 OER 的便携式设备制造方法，以产生可呼吸的氧气。在本文中，我们展示了基于电化学的析氧装置的简单设计和制造。该装置包括一个装有 1 M 氢氧化钠 (NaOH) 水溶液的塑料罐（5 升），在顶部，创建了两个孔，用于浸入不锈钢棒阴极和阳极电极，将它们连接起来到电源。在提供13V电压和9.5A电流时，以气泡形式开始产生氧气。产生的氧气通过塑料管收集。它还提供氢气，可以单独储存。在初始阶段，产氧速率为 2.0 升/分钟。5A电流。产生的氧气通过塑料管收集。它还提供氢气，可以单独储存。在初始阶段，产氧速率为 2.0 升/分钟。5A电流。产生的氧气通过塑料管收集。它还提供氢气，可以单独储存。在初始阶段，产氧速率为 2.0 升/分钟。
