During the laser application process, laser energy is usually converted into heat energy, causing high temperature, which affects the (high-speed) aircraft in routine flight. A completely novel photochemical method was investigated to potentially minimize the energy effect of the laser beam. Ag nanoparticles/C3N4 were synthesized by an ultra-low temperature reduced deposit method with Ag mean diameters of 5-25 nm for photofixation of N2. The absorption performance of laser can be improved by using appropriate charge density and small size Ag metal particles. The energy absorption rate was 7.1% over Ag/C3N4 (-40) at 5 mJ/cm2 of laser energy.
在激光应用过程中，激光能量通常会转化为热能，导致温度升高，这会影响常规飞行中的（高速）飞行器。研究了一种全新的光化学方法，以潜在地最小化激光束的能量效应。通过超低温还原沉积法合成了平均直径为5-25 nm的Ag纳米颗粒/C3N4用于N2的光固定。使用适当的电荷密度和小尺寸的Ag金属颗粒可以提高激光的吸收性能。在5 mJ/cm2的激光能量下，Ag/C3N4（-40）的能量吸收率为7.1%。
