Solar Driven Self-Floating MXene-rGO Aerogel for Hydrogen Production From Formic Acid
【摘要】 利用丰富的太阳能资源转化为绿色清洁能源具有成本低、无污染等特点,展现出了广阔的应用前景。本文提出了一种太阳能驱动的漂浮式制氢方法,通过界面加热和传质增强,实现了光热的迅速转换以及传质速率的提升。研究结果表明,漂浮式系统在1 k W m-2的光照下,利用甲酸实现了72.1 mmol g-1 h-1的制氢速率,且在5次循环后依然维持稳定。另外,漂浮式系统在催化剂回收的过程中,节省了过滤等耗能手段,进一步证实了漂浮式系统在太阳能室温制氢中的应用潜力。
【Abstract】 The utilization of abundant solar energy resources in the production of green and clean energy exhibits the characteristics of cost-effectiveness and environmental friendliness, thereby demonstrating a wide range of potential applications. Herein, this work presents the solar-driven floating hydrogen production system, which effectively achieves rapid photothermal conversion and enhances mass transfer rates through interfacial heating and improved mass transfer. The results demonstrate that the system achieves a hydrogen evolution rate of 72.1 mmol g-1h-1utilizing formic acid under an irradiation intensity of 1 kW m-2and maintains excellent stability even after undergoing five cycles. More importantly, the floating system also demonstrates its potential for the application of solar energy in room-temperature hydrogen production by efficiently saving energy-consuming processes like filtration during catalyst utilization.
