Abstract Solar‐driven photocatalytic CO 2 reduction coupled with the oxidation of organic compounds to value‐added chemicals is a promising strategy, which can utilize both photogenerated electrons and holes. Here, gradient alloyed CdS@Zn x Cd 1‐x S@ZnS quantum dots (quasi‐Type II band structure) capped Cl − ligands demonstrate great potential in simultaneous conversion 1‐phenylethanol into syngas pinacol. The passivation maximizes exposure surface‐active sites improves their electronic structure, providing prerequisite for efficient execution redox reactions. More importantly, p–π conjugation between chloride‐ion benzene ring provides bridge ultrafast transfer holes, greatly promotes activation Cα─H bond release mass reactive free hydrogen. This process effectively lowers thermodynamic energy barrier reduction, even as excessively high kinetic barriers arising from accumulation excess protons also enable them self‐couple, leading generation (CO ≈ 75 mmol g −1 h ; selectivity 69.86%). work insights future artificial photosynthesis achieve activity cost‐effective storable renewable resources co‐production substances through synergistic oxidation.

The design of multi-purpose decontaminants with environmentally friendly characteristics, low cost, and high efficiency in removing pollutants from the environment is an effective economic strategy for maintaining long-term development ecosystem. Based on killing two birds one stone, egg white (EW)/TiO2 hydrogel a porous structure devised as bio-adsorbent using waste eggs nearing their expiration date simultaneously achieving efficient removal organic dyes inactivation microorganisms industrial wastewater. characterizations its morphology composition scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) theory, energy-dispersive spectrometry (EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analyzer (TGA) validate successful synthesis EW/TiO2. maximum adsorption capacity EW/TiO2 333.172 mg∙mL−1 according to Langmuir model. photodegradation methyl blue (MB) solution under irradiation via xenon lamp used assess photocatalytic behavior Among different samples, 5 wt% TiO2-doped shows 99% 120 min irradiation. Finally, antibacterial properties are evaluated by calculating bacterial survival rate against Escherichia coli (E. coli). photocatalyst exhibits 90.4%, indicating that possesses positive activity effectively inhibiting growth bacteria, which suitable wastewater treatment over long period time.
