Enhanced hydrogen selectivity via photo-engineered surface defects for methanol steam reformation using zinc oxide–copper nanocomposite catalysts

Autor: Salim Al-Harthi, Karthik Lakshman, Joydeep Dutta, Supamas Danwittayakul

Publikováno v: Applied Catalysis A: General. 471:63-69

Methanol steam reformation (MSR) to produce hydrogen (H2) gas using copper on zinc oxide (Cu/ZnO) supported catalysts is attractive due to the simple and low cost preparation process of the catalyst. H2 yield from MSR is proportional to total catalys

Dual-Sensitization via Electron and Energy Harvesting in CdTe Quantum Dots Decorated ZnO Nanorod-Based Dye-Sensitized Solar Cells

Autor: Joydeep Dutta, Karthik Lakshman, Soumik Sarkar, Abhinandan Makhal, Samir Kumar Pal, Tanujjal Bora

Publikováno v: The Journal of Physical Chemistry C. 116:14248-14256

Different-sized, 3-mercaptopropionic acid (MPA) stabilized CdTe quantum dots (QDs) have been prepared in aqueous solution, and potential cosensitization of such QDs in ZnO nanorod (NR)-based dye-sensitized solar cells (DSSCs) has been established. Th

UVA radiation induced ultrafast electron transfer from a food carcinogen benzo[a]pyrene to organic molecules, biological macromolecules, and inorganic nano structures

Autor: Karthik Lakshman, Soumik Sarkar, Joydeep Dutta, Samir Kumar Pal, Soma Banerjee

Publikováno v: The journal of physical chemistry. B. 117(14)

Reactions involving electron transfer (ET) and reactive oxygen species (ROS) play a pivotal role in carcinogenesis and cancer biochemistry. Our present study emphasizes UVA radiation induced ET reaction as one of the key aspects of a potential carcin
