| 摘 要： | 为实现光合细菌(PSB)产氢过程的光分频利用,用六硼化镧(LaB_6)和壳聚糖制备了光热转换发光发热生物材料,研究了不同LaB_6纳米颗粒的生物材料在可见光下的吸光特性和光热转换特性。研究发现:该生物材料能较好地透过510~650 nm波长的光为PSB产氢供给光能,而其他波段的光用于激发LaB_6粒子产热为PSB提供热能。LaB_6纳米颗粒的吸光度及光热转换能力受颗粒尺寸影响显著,当生物材料中LaB_6颗粒平均水力直径为295 nm时,12 min内的温升速率为0.41℃/min,是载玻片的5.4倍。

| Abstract: | To realize spectral beam splitting technology in the bioprocess of hydrogen production by photosynthetic bacteria (PSB), a luminous exothermic biomaterial based on lanthanum hexaboride (LaB6) and chitosan was fabricated.The absorption spectra and photothermal properties of biomaterial with different LaB6 particles were investigated in the visible spectrum.The results show that the biomaterial can transmit the light in the spectrum of 510-650 nm for PSB, and other light energy will convert to heat energy for PSB.In addition, the absorption and photothermal performance of LaB6 particles are significantly effected by the particle size.When the average hydraulic diameter of LaB6 particles in the biomaterial is 296 nm, the rate of temperature rise is 0.41 ℃/min over 12 min, which is 5.4 times of glass slide. |
