Summary: Zn2SnO4(ZTO)/ZIF-8 nanocomposite photocatalysts were prepared using solution method and hydrothermal method. The addition of ZIF-8 improved the photocatalytic activity of ZTO by inhibiting the recombination of photoelectron-hole pairs. The composite exhibited slightly improved adsorption performance due to the high specific surface area of ZIF-8. With 0.4 wt%ZIF-8, the ZTO nanocomposite achieved a photocatalytic activity of 75% in the removal of 20 mg/L MB dye solution after 120 min.

Summary: A simple and reproducible self-templating method was developed to synthesize silver nanoparticles decorated on CNTs/TiO2 nanocomposite using nanosecond pulsed laser ablation. The resulting nanocatalysts showed enhanced photocatalytic degradation of methylene blue dye contaminant. Morphology, heterostructure, and the nature of incorporation of the nanocomposite catalysts were confirmed by TEM and SEM microscopy. XRD analysis confirmed the crystalline nature of the nanocatalysts. PL analysis provided information about surface defects and electron-hole recombination properties of the prepared nanocatalysts. Efficient ultraviolet light-induced photodegradation of the dye was achieved using the TiO2/CNT and Ag/TiO2/CNT nanocomposite catalysts.

Compartmental models, such as the enhanced SEIRV model, are used to predict the severity of the pandemic. The proposed model incorporates vaccination as an additional compartment to analyze the impact on COVID-19 severity. Simulations under different conditions show that social distancing measures can slow down the epidemic growth rate. The vaccination of infants and children is considered for future work.
