Meanwhile, further studies were conducted on the influence mechanism of Adv.Pre-Deg on subsequent hydrogenation, and some microscopic detection was applied to characterize the effect of Adv.Pre-Deg on the following hydrogenation. The results indicated that Adv.Pre-Deg only slightly influenced the crystallinity, dangling bonds, and defects within the surface dielectric layer, which illustrated that Adv.Pre-Deg hardly harmed the dielectric layer.

The heat collection efficiency in DASC is constrained by the stability and optical absorption capacity of nanofluids. Carbon quantum dots (CQDs) nanofluids are used in DASC due to the excellent dispersion stability. However, the optical absorption range of current CQDs is primarily confined to the ultraviolet region, resulting in the visible and near-infrared regions of sunlight being underutilized. To solve this problem, this study synthesized novel N-doped carbon quantum dots (FPNCQDs) using ammonium bifluoride (NH<sub>4</sub>F) and perylene derivatives. The addition of NH<sub>4</sub>F and perylene derivatives during synthesis increased the sp<sup>2</sup> conjugated structure and the content of graphite N in FPNCQDs. The doping of N, especially graphite N, significantly reduces the band gap by injecting excess electrons into the unoccupied π∗ orbitals. The temperature of FPNCQDs/EG nanofluids increased from 24 °C to 65.7 °C within 60 min, demonstrating excellent photothermal conversion performance. What's more, the FPNCQDs/EG nanofluids achieved high stability with nearly consistent transmittance over a 14-day storage test. Finally, a theoretical model for the photothermal conversion process of the nanofluids was developed to investigate the effect to carbon quantum dots on the solar collection performance. The simulation results indicated that the FPNCQDs/EG nanofluids at 10 ppm demonstrated the highest solar collection efficiency considering both photothermal conversion and heat loss from the surface.
