Professor D. Amaranatha Reddy's research lab specializes in the design and synthesis of advanced nanomaterials for sustainable energy applications, with a primary focus on solar-driven photocatalytic hydrogen production. The lab develops noble-metal-free, highly efficient, and stable photocatalysts using earth-abundant materials such as CdS, MoS₂, ZnS, and graphene-based composites. Key research directions include nanostructure engineering, defect modulation, and heterojunction formation to enhance charge separation and surface reactivity. The lab emphasizes green synthesis methods and scalable fabrication techniques to enable practical, large-scale applications in renewable energy conversion.

Solar-driven photocatalytic hydrogen evolution is important to bring solar-energy-to-fuel energy-conversion processes to reality. However, there is a lack of highly efficient, stable, and non-precious photocatalysts, and catalysts not designed completely with expensive noble metals have remained elusive, which hampers their large-scale industrial application. Herein, for the first time, a highly efficient and stable noble-metal-free CdS/WS<sub>2</sub> -MoS<sub>2</sub> nanocomposite was designed

Designing porous nanostructures with unprecedented functionalities and an effective ability to harvest the maximum energy region of the solar spectrum and suppress the charge-carrier recombination rate offers promising potential for sustainable energy production. Although several functional porous nanostructures have been developed, high-efficiency materials are still needed.

Development of novel low price porous nanostructures with robust photocatalytic hydrogen generation rate and high durability is critical to help to meet the future energy demand. A prominent number of sunlight active semiconductor photocatalyst nanostructures have been formulated for the aforementioned photocatalytic reactions. However, their practical application has been limited by low efficiency and unstability induced by the rapid recombination of charge carriers. To effectively reduce the r
