“…Once suitable supports are used, the supported nanostructured photocatalyst systems offer several advantages, including better dispersion and reduced agglomeration, enhanced surface area, easy handling and recovery, and improved recyclability of the photocatalyst particles [30,33]. Moreover, as discussed in the following sections, the supported photocatalytic materials' optical, thermal, and photocatalytic properties can be modified, and often improved, owing to different support-photocatalyst interactions [27,29,[38][39][40][41].…”

Heterogeneous photocatalysis employing semiconductor oxide photocatalysts is a sustainable and promising method for environmental remediation and clean energy generation. In this context, nanostructured photocatalysts, with at least one dimension in the 1-100 nm size regime, have attracted ever-growing attention due to their unique and often enhanced sizedependent physicochemical properties. While their reduced size ensures enhanced photocatalytic performance, the same makes it difficult and time/energy-demanding to remove/recover such nanostructured photocatalysts from aqueous media. This fundamental limitation has paved the way towards developing supported nanophotocatalysts where the active photocatalytic nanostructures are coated on the surface of polymeric or inorganic support materials, often in a core@shell conformation. This arrangement solves the problem of photocatalysts' recovery for effective reuse or recycling and leads to improved and desired target properties due to specific photocatalyst-support interactions. While the enhanced physicochemical properties of supported photocatalysts have been widely studied in many target applications, the role of support-photocatalysts interactions in improving these properties remains unexplored. This review article provides an updated viewpoint on the photocatalyst-support interactions and the resulting unique physiochemical properties important for diverse photochemical applications and the design of practical devices. While exploring the properties of supported nanostructured metal oxide/ sulfides photocatalysts such as TiO 2 and MoS 2 , we also briefly discuss the common strategies employed to coat the active nanomaterials on the surface of different supports (organic/polymeric, inorganic, active, inert, and magnetic).

“…Electrospinning techniques are simple, have low operation costs, and continuously produce nanofibers in bulk production (Kim et al,2021). The significant benefits of electrospinning are required simple equipment compositions and have high flexibility in nanofiber orientations (Liao et al,2018).…”

Due to rapid urbanization and industrialization, water demand has increased worldwide. The availability of potable water is becoming more difficult in the global scenario. Hazardous pollution disposal by the industries to the nearest stream and search for the facile environmentally friendly technologies capable of treating these pollutants become more challenging. Effluent disposal consisting of the dyes without proper pre-treatment adversely affects the aquatic life and ecological system as they are carcinogenic and highly toxic. Dyes in the water are becoming a significant problem in the current scenario and attracted many researchers to research the current topic. Even though the conventional treatment options are available for treating polluted water, still they are not enough for the demand and supply. Thus, new state-of-the-art technologies are required to meet the demand and supply. Titanium dioxide nanofibers synthesized by electrospinning techniques have proven to be new nanomaterials gaining prominence in science. Several researchers are using these fibres by fabricating them into a thin film for pollutant removal and water treatment. They are gaining much importance as they perform best in treating water containing both organic and inorganic loads. The present review provides insights into the background and the origin of the electrospun nanofibers and preparation mechanisms. Further, we identified 25 widely used titanium dioxide electrospun nanofibers with various combinations in removing the dyes from the aqueous medium.
