摘要

为解决光电催化分解水反应器中气泡长时间附着于光电极表面，从而导致有效活化面积减少和产气效率下降的问题，构建耦合振动系统的光电分解水制氢气泡动力学可视化实验平台，提出通过给电极施加不同振幅和频率振动以加速气泡脱离光电极表面的方法。首先，记录静止电极表面单个气泡演化过程中的电信号和几何参数；然后，对比不同频率及振幅下气泡生长过程中电流和电势的变化情况；最后，分析振动对气泡几何特性的影响。研究结果表明：振动频率和振幅的增加能够提高反应过程中的光电流，降低电势，使得反应阻力下降；增加振动频率和振幅均能显著减小气泡脱离尺寸，从而加速气泡的脱离；当振动频率为70 Hz时，施加振动后气泡的脱离直径比无振动时最大减小了321 μm，减小幅度约为48%；施加振动后，气泡直径为生长时间的幂函数，且气泡生长依次受惯性和化学反应控制。该研究可为光电催化分解水反应器的优化设计提供新思路。

Abstract

To address prolonged attachment of bubbles to the photoelectrode surface of photoelectrochemical water splitting reactor

which leads to smaller effective activation area and lower gas production efficiency

an experimental platform was constructed for the visualization of the dynamics of bubbles in photoelectrochemical water splitting for hydrogen production with coupled vibration system

and a method was proposed to accelerate the detachment of bubbles from the photoelectrode surface by applying vibrations with different amplitudes and frequencies to the electrodes in this paper. Firstly

the electrical signals and geometrical parameters during the evolution of individual bubbles on the stationary electrode surface were recorded. Next

the changes in the current and potential during bubble growth at different frequencies and amplitudes were compared. Finally

the effect of vibration on the geometrical properties of the bubbles was analyzed. The results show that the larger the vibration frequency and amplitude

the larger the photocurrent of the reaction and the smaller the overpotential

that is

the reaction resistance decreased. Increasing the vibration frequency and amplitude could significantly reduce the size of bubble detachment

thus accelerating the bubble detachment. At a vibration frequency of 70 Hz

the detachment diameter of bubbles was reduced by a maximum of 321 μm compared with no vibration

a reduction of about 48%. After vibration application

the bubble diameter was a power function of the growth time

and the bubble growth was controlled by inertia and chemical reaction in turn. This study can provide insights for optimizing the design of photocatalytic water-splitting reactors.
