This study introduces a new strategy for the environmentally friendly catalytic degradation of Reactive Red 24 (RR24) dye using sunlight. We developed cost-effective quaternary nanocomposite by immobilizing sodium alginate biopolymer over bioengineered Co-Zn-Ce nanoparticles, forming an SA@Co–Zn–Ce (where SA means alginate). composite also demonstrated exceptional antioxidant potential approximately 89%, attributed to synergistic effect and green-synthesized Co–Zn–Ce nanoparticles (biosynthesized Ocimum sanctum leaf extract as reducing agent). Scanning electron microscopy revealed grain sizes 28.6 nm NPs 25.59 nanocomposites (NCs). X-ray diffraction showed particle 16.87 15.43 nm, respectively. exhibited zeta 1.99 mV, whereas alginate-anchored −7.99 mV. indicated entrapment negatively charged ions from alginate, altering surface charge characteristics enhancing photocatalytic RR24. Dynamic light scattering average size 81 NCs, with larger due influence water molecules in colloidal solution affecting hydrodynamic diameter measurement. The NCs CO2 adsorption capacity 3.29 mmol/g at 25 °C 4.76 40 °C, indicating temperature-dependent variations capabilities. specific area oxide NPs, measured Brunauer–Emmett–Teller (BET) analysis, was found be 167.346 m2/g, 24.14 m2/g. BJH analysis pore diameters 34.60 Å 9.26 NCs. Although immobilization on did not increase sites porosity composite, evidenced N2 adsorption–desorption isotherms, still high efficiency

We scrutinize the environmental policies' efficacy in reducing ecological footprint by interweaving two other vibrant parameters of degradation mitigation, i.e., renewable energy sources and innovation. To this end, we apply a Cross-Sectional Autoregressive Distributed Lags (CS-ARDL) approach to analyze panel time-series data (1990–2018) context OECD countries. Our analysis shows that policy significantly reduces through innovation channels. findings also support idea policy's effectiveness is conditional on countries' bio-capacity surplus/deficit level industrialization. The overall hold up well presence cross-sectional dependence, short-run heterogeneity, long-run homogeneity under respective sample. underscore need for more stringent policies, supported technological advancements clean initiatives, mitigate impact human economic activities natural resources.
