AI Article Synopsis
- A new combustion method was created to produce carbon and silver co-modified zinc oxide (ZnO) nanocomposites (NCs) to improve their effectiveness as photocatalysts.
- The study found that adding silver significantly boosts the photocatalytic activity, with an optimal Ag to Zn ratio of 2%, leading to a 150% increase in degradation rates under visible light compared to carbon-ZnO NCs, and a staggering 1233.3% improvement over pure ZnO.
- The presence of silver resulted in small particles (about 10 nm) on the surface of carbon-ZnO NCs, suggesting a collaboration between silver and carbon that enhances the photocatalytic performance when exposed to visible light.
Article Abstract
A combustion method was developed to synthesize the C and Ag co-modified ZnO NCs to enhance its photocatalytic efficiency and practicability. The results showed that the doped Ag was significant to promote the photocatalytic activity, and the optimum content was 2% molar ratio of Ag to Zn atom. The degradation rate under visible light increased by 150% compared with C-ZnO NCs, while by more 1233.3% than pure ZnO photocatalyst. There were some new little particles with grain size about 10 nm on the C-ZnO NCs surface, which may state for the existence of Ag atoms. The synergy effect of Ag and carbon elements was proposed to explain the mechanism of enhanced photocatalytic performance under visible light irradiation.
