Focusing on the above problems, this study designed an undivided electrolytic cell system based on Z

　　Csp3-H bond exists widely in all kinds of organic compounds, and its selective oxidation conversion is the key to synthesize high value-added chemicals. Traditional oxidation methods usually rely on stoichiometric oxidants or noble metal catalysts, which have some problems such as high cost and serious environmental pollution. In recent years, electrochemical synthesis, as a green and efficient synthesis strategy, has attracted extensive attention. The progress of electrochemical catalysis has effectively reduced the dependence on precious metals, enhanced the catalytic activity and selectivity, and promoted the development of alcohol/alkane oxidation towards high efficiency and low cost. Although the green oxidation technology has made great progress, most systems still have shortcomings such as low current density, poor amplification and dependence on separated electrolytic cells, which limits the industrial application. 　　《在火旁冷却》是一款营火模拟游戏。在游戏中，玩家可以在各种不同的放松场所，包括海滩、森林和白雪皑皑的山顶，建立和维护营火。他们将需要处理不同的天气和气候，因为他们的篝火增长到10级前进。 　　多达四个朋友或家庭成员可以在线或通过GameShare聚集在火堆周围。此外，如果连接了兼容的外部USB-C摄像头，您可以使用CameraPlay出现在游戏中。
