Green Photocatalyst

edit

Green photocatalyst are semiconductor materials derived from environmentally friendly sources that use solar energy to catalyze chemical reactions[1][2]. These materials, often nano-structured for enhanced efficiency, represent a sustainable approach of nanotechnology advancement to address global challenges related to clean energy production and environmental remediation[3]. Green photocatalyst are synthesized from natural, renewable, and biological resources, such as plant extracts, biomass, or microorganisms, minimizing the use of toxic chemicals and reducing the environmental impact associated with conventional catalyst production[4][5]. The unique properties of these materials, including their ability to absorb visible light, facilitate charge separation, and exhibit high catalytic activity, make them promising candidates for a wide range of applications, including the degradation of organic pollutants in wastewater, the reduction of harmful gases, and the production of hydrogen or solar fuels[6].

A photocatalyst is a material that absorbs light energy to initiate or accelerate a chemical reaction without being consumed in the process[7]. This process, known as photocatalysis, uses semiconducting materials to generate electron-hole pairs upon light irradiation. These photogenerated charge carriers then migrate to the surface of the photocatalyst and interact with adsorbed species, triggering redox reactions[8].

The Need for Green Photocatalyst

edit

The increasing demand for sustainable and environmentally friendly technologies has spurred the development of green photocatalyst[9]. Traditional photocatalyst synthesis often involves the use of harsh chemicals, high temperatures, and significant energy consumption, leading to concerns about their environmental impact and economic viability[10]. Green photocatalyst aim to address these limitations by utilizing renewable and environmentally benign materials and synthesis processes[1][2].

Research in the field of green photocatalyst is rapidly advancing, with current trends focusing on developing more efficient, stable, and versatile materials for a wider range of applications. Advancements in green photocatalyst design are centered on improving their light absorption capabilities, enhancing charge separation and transfer efficiency, and tailoring their catalytic activity for specific applications[129]. Researchers are exploring novel materials, such as metal-organic frameworks and two-dimensional nanomaterials, to achieve these goals[130][131]. Another key focus area is enhancing the stability and reusability of green photocatalyst[132]. Efforts are underway to develop materials that can withstand multiple cycles of use without significant loss in performance, contributing to their practical viability and reducing costs associated with catalyst replacement. Beyond wastewater treatment and air purification, emerging applications for green photocatalyst are being explored in fields like solar energy conversion, hydrogen fuel production, and environmental sensing. For example, green photocatalyst are being investigated for their potential use in dye-sensitized solar cells to convert sunlight into electricity[133][134], and in the production of hydrogen fuel from water splitting using sunlight as an energy source[135][136]. Furthermore, their unique properties make them suitable for developing sensors for detecting pollutants or other analytes in the environment[137][138][139].
