我们报道了一种基于表面工程玻璃波导的光流控反应器系统。光催化剂被涂覆在波导表面上，并在光照射下被激活。在传统的设计中，光沿着波导沿着逐渐扩散和衰减，导致光能量的不均匀分布。本文提出了一种通过梯度腐蚀对玻璃波导表面进行改性的方法，以延长光的传输长度，使光的折射更加均匀。研究了波导尺寸和蚀刻图案对光折射强度分布沿着传输的影响。这些具有特殊设计表面的波导被应用于光流体反应器中，用于将CO2光催化转化为燃料。
We report a surface-engineered glass waveguide based optofluidic reactor system. Photocatalyst is coated on waveguide surfaces and is activated under light irradiation. In traditional design, light gradually spreads and diminishes along the waveguide, leading to non-uniform distribution of light energy. Here we present a method for modifying glass waveguide surfaces through gradient etching, to extend light transmission length and make light refraction more uniform. The effect of waveguide dimensions and etching patterns on the light refraction intensity profiles along transmission was examined. These waveguides with specially designed surfaces were applied in an optofluidic reactor for photocatalytically converting CO2 into fuels.
