Effectively recycling these materials is crucial for resource utilization and environmental protection. Currently, recycling processes are conducted separately, increasing overall treatment costs. This study employs silicon recovered from spent PV panels as a reducing agent to facilitate the reduction of LiCoO<small>₂</small> cathodes in spent LIBs. In this process, high-valence cobalt (Co<small>³⁺</small>) is reduced to low-valence cobalt (Co<small>²⁺</small>), while lithium is selectively leached as water-soluble Li<small>₂</small>SiO<small>₃</small>. The solid residue is further processed through wet magnetic separation to recover CoO/Co, effectively reducing the need for traditional solvent extraction and achieving efficient separation of Li and Co. Under optimal conditions (roasting at 700 °C for 30 minutes with a mass ratio of 20%), the recovery rates of Li and Co reached 95.32% and 97%, respectively. The reaction mechanism of silicon reduction roasting was analyzed using TG, XRD, SEM, and XPS characterization techniques. The reaction proceeded through a solid–solid mechanism, with no mass loss or gaseous pollutant emissions during the roasting process. The Li<small>₂</small>SiO<small>₃</small> solution obtained from water leaching can be further processed by adding Na<small>₂</small>CO<small>₃</small> to precipitate Li<small>₂</small>CO<small>₃</small>, which, together with the recovered CoO/Co product, can be used to re-synthesize LiCoO<small>₂</small> cathodes.

The paper reports a dual-emissive fluorescent probe based on arginine- and serine-functionalized boron-doped graphene quantum dots (RSB-GQDs), synthesized <em>via</em> a one-step thermal annealing strategy using citric acid, arginine, serine, and boric acid as precursors. The resulting RSB-GQD offers a unique dual fluorescence emission at distinct excitation wavelengths: intense blue fluorescence (<em>λ</em><small>_em</small> = 460 nm) upon 370 nm ultraviolet excitation, and robust yellow fluorescence (<em>λ</em><small>_em</small> = 560 nm) under 480 nm visible light excitation. The boron doping effectively modulates the electronic structure by narrowing the bandgap, significantly enhancing visible light absorption and enabling nearly equal emission intensities for both fluorescence bands.

The quenching efficiency demonstrates a linear correlation with Fe<small>³⁺</small> concentration (0–50 μM), achieving an ultra-low detection limit of 75 nM (<em>S</em>/<em>N</em> = 3) and outperforming conventional methods.
