Light-driven Photocatalysis Research Articles

Light-driven photocatalysis as an effective tool for degradation of antibiotics.

Antibiotic contamination has become a severe issue and a dangerous concern to the environment because of large release of antibiotic effluent into terrestrial and aquatic ecosystems. To try and solve these issues, a plethora of research on antibiotic withdrawal has been carried out. Recently photocatalysis has received tremendous attention due to its ability to remove antibiotics from aqueous solutions in a cost-effective and environmentally friendly manner with few drawbacks compared to traditional photocatalysts. Considerable attention has been focused on developing advanced visible light-driven photocatalysts in order to address these problems. This review provides an overview of recent developments in the field of photocatalytic degradation of antibiotics, including the doping of metals and non-metals into ultraviolet light-driven photocatalysts, the formation of new semiconductor photocatalysts, the advancement of heterojunction photocatalysts, and the building of surface plasmon resonance-enhanced photocatalytic systems.

Recent developments in polydopamine-based photocatalytic nanocomposites for energy production: Physico-chemical properties and perspectives

Light-driven photocatalysis might address many global energy concerns due to its implications for hydrogen production and the imperative need to reduce fossil fuel dependency. Polydopamine (PDA) is a popular mussel-inspired material with extensive applicability in biomedical and drug delivery fields, which has recently been gathering attention in the fields of catalysis and photocatalysis. PDA is highly attractive for catalysis due to its large number of functional groups and its easy polymerization on virtually any surface. In photocatalysis, however, its properties have not been well described and strongly depend on the generation of heterojunctions (PDA/Semiconductor). In this review, we summarize the latest developments and studies on photocatalytic nanocomposites based on PDA. We will introduce general aspects such as structure and polymerization control. Then, we will focus on aspects of relevance for photoactive materials, such as chromatic control and electrical properties. We will present and discuss the recent literature on metal oxides and metal sulfides and some emergent materials focusing on photoactive and photocatalytic applications. Finally, we will outline some of the opportunities in the field. We hope this review serves as a reference for researchers and allows the growing community to focus on future developments for PDA-based photocatalytic nanocomposites.
