Research Overview

My research lies at the intersection of materials chemistry, catalysis, and sustainable energy technology. I develop and investigate nanostructured materials and catalytic systems for transforming greenhouse gases and waste into valuable fuels and chemicals, using sunlight and electrochemical energy as drivers.

Photocatalytic CO₂ Reduction

I have developed various catalyst systems, including metal-doped TiO₂, metal-deposited TiO₂, TiO₂/graphene composites, TiO₂/MoSe₂ heterostructures, and ternary hybrid nanocomposites. These materials are tailored to enhance solar light absorption, charge carrier separation, product selectivity, and long-term stability. My work primarily focuses on the gas-phase photoreduction of CO₂ using water vapor as the proton source to generate fuels like CO, CH₄, and C₂H₆.

Photoelectrochemical CO₂ Conversion

Motivated by a growing interest in photoelectrode design, I undertook short-term work involving the fabrication of multilayered architectures by integrating active catalysts onto conductive substrates. These systems are optimized for solar-assisted CO₂-to-liquid fuel conversion in PEC (photoelectrochemical) cells. My research focuses on enhancing interfacial charge transfer, improving catalytic selectivity, and maintaining stability under reaction conditions.

Waste Chemical Degradation

I explored the use of metal chalcogenide-based photocatalysts for the solar-driven degradation of hazardous industrial waste chemicals such as dyes (methylene blue, indophene, etc). Herein, I employed various chalcogenide-based materials such as CdS and CdSe, along with their composites with graphene and polymers like PVP and PVA. These systems are designed to enhance visible-light absorption and reactive species generation. My research supports environmental remediation and contributes to sustainable pollutant management through green chemistry principles. 

Thermoelectric Materials

I have also synthesized metal chalcogenide/graphene composites for thermoelectric applications. These materials are designed to convert low-grade waste heat into electrical energy, offering an energy-harvesting solution for decentralized power systems.
