A composite photocatalyst, sliver/graphitic carbon nitride/pre-treated carbon fiber paper (Ag/g-C₃N₄/t-CFP), has been innovatively designed and successfully fabricated by loading Ag and g-C₃N₄ species on t-CFP using the combined methods of thermal polymerization and improved electroless plating (IEP) through ultrasonic spray atomization (USA). A micro-droplet system, USA is able to eliminate the adverse influence of concentration gradient effectively. The samples obtained were carefully characterized in terms of morphology, phase, chemical structure, and optical performance. Results suggested that compared with the conventional electroless plating (CEP), IEP strategy could ensure a better dispersibility and smaller size of Ag nanoparticles. Accordingly, the IEP-prepared Ag/g-C₃N₄ photocatalyst on t-CFP (ACNT-iep) exhibited a pseudo-first-order kinetics constant 12 times higher than that of the neat g-C₃N₄ on t-CFP for methylene blue (MB) degradation. Photoluminescence (PL) and electrochemical impedance spectra (EIS) demonstrated a more efficient separation of photogenerated carriers in ACNT-iep at the same time. The photocatalytic activity of ACNT-iep could be maintained at a high level over five cycles.

银和碳氮化碳/预处理碳纤维纸（Ag / gC ₃ N ₄ / t-CFP）的复合光催化剂已经过创新设计，并通过负载Ag和gC ₃ N ₄得以成功制备通过热喷涂和超声喷涂雾化（美国）改进的化学镀（IEP）相结合的方法，将t-CFP上的有机物沉积在t-CFP上。美国的微滴系统能够有效消除浓度梯度的不利影响。对获得的样品进行了形态，相，化学结构和光学性能方面的仔细表征。结果表明，与传统的化学镀（CEP）相比，IEP策略可以确保更好的分散性和较小的Ag纳米颗粒尺寸。因此，在t-CFP（ACNT-iep）上用IEP制备的Ag / gC ₃ N ₄光催化剂表现出的拟一级动力学常数比纯gC ₃ N ₄高12倍。在t-CFP上进行亚甲基蓝（MB）降解。光致发光（PL）和电化学阻抗谱（EIS）证明了ACNT-iep中光生载流子的更有效分离。ACNT-iep的光催化活性可以在五个周期内保持较高水平。
