Nickel-decorated carbocatalysts were synthesized by the evaporation-induced self-assembly (EISA) method. The influence of metal content and pyrolysis temperature upon photoactivity was assessed through rhodamine B degradation under UV irradiation. characterization revealed a mesoporous framework with granular morphology composed amorphous carbon, where influenced dispersion on carbon surface. primary metallic phases consisted elemental nickel crystallites carbide phases. kinetic parameters for adsorption dye photodegradation irradiation determined compared to TiO2-P25. Correlations found between parameters, photocatalytic activity, content, method (one-step vs. two-step pyrolysis), temperature. sample 1:1:0.25 tannin/Pluronic®F-127/Ni weight ratio pyrolyzed at 700 °C exhibited highest photoactivity, achieving rates up 68 2.5 times greater than photolysis In terms normalized catalysts, it can be concluded that present Ni-based catalysts are two orders magnitude more photoactive TiO2-P25 irradiation, opening door indoor UV-driven photoreactors. These findings demonstrate EISA is an effective, low-cost, ecofriendly approach synthesizing Ni-decorated carbocatalysts.
