Abstract The removal of persistent antibiotics from wastewater is a critical challenge for sustainable environmental remediation. Photocatalysis offers promising solution, yet its efficacy often limited by inefficient structural design and inadequate activation molecular oxygen (O 2 ). Here, we report rod‐shaped ZnIn S 4 photocatalyst enriched with strategically engineered sulfur vacancies (Sv‐ZIS) that address these bottlenecks. introduction narrows the bandgap, enhancing visible‐light absorption inducing defect levels facilitate superior charge separation transfer. These also boost adsorption energy chemisorption O molecules, thereby catalyzing production superoxide radicals (˙O − ) high efficiency. rod‐like morphology further augments interaction tetracycline molecules reactive species (ROS), significantly photocatalytic degradation performance. Sv‐ZIS achieves rates nearly fourfold greater than bulk counterpart (Bulk‐ZnIn ), underscoring transformative potential. This work pioneers novel engineering strategy, advancing development high‐performance photocatalysts tackling antibiotic pollutants in treatment.

Carbon dots (CDs), which are nanoscale carbon-based materials, have gained substantial attention because of their exceptional catalytic properties and environmental applications. This chapter explores the multifaceted role CDs in processes, focusing on significance addressing critical industrial challenges. The also discusses utilization as catalysts for carbon dioxide (CO2) conversion, a pressing issue context climate change sustainable energy production. In addition, it mechanisms by enhance CO2 reduction, offering insights into potential mitigating greenhouse gas emissions producing valuable chemicals fuels. Furthermore, how facilitate hydrogen (H2) evolution, key aspect clean generation. Their unique promoting water splitting other hydrogen-related reactions discussed, shedding light transition to hydrogen-based economy. Finally, this addresses application various organic reactions, highlighting efficiency chemical transformations, green synthesis, manufacturing processes.
