TL;DR: A series of CdSe quantum dot-sensitized TiO2 heterostructures have been synthesized, characterized, and tested for the photocatalytic reduction of CO2 in the presence of H2O.
Abstract: A series of CdSe quantum dot (QD)-sensitized TiO2 heterostructures have been synthesized, characterized, and tested for the photocatalytic reduction of CO2 in the presence of H2O. Our results show that these heterostructured materials are capable of catalyzing the photoreduction of CO2 using visible light illumination (λ > 420 nm) only. The effect of removing surfactant caps from the CdSe QDs by annealing and using a hydrazine chemical treatment have also been investigated. The photocatalytic reduction process is followed using infrared spectroscopy to probe the gas-phase reactants and gas chromatography to detect the products. Gas chromatographic analysis shows that the primary reaction product is CH4, with CH3OH, H2, and CO observed as secondary products. Typical yields of the gas-phase products after visible light illumination (λ > 420 nm) were 48 ppm g−1 h−1 of CH4, 3.3 ppm g−1 h−1 of CH3OH (vapor), and trace amounts of CO and H2.

Journal ArticleDOI
TL;DR: In this article, the authors reviewed the interconnect materials and coatings for metallic interconnects for solid oxide fuel cells (SOFCs) and compared them with other SOFC ceramic components, and found that the requirements of interconnect are the most demanding, i.e., to maintain high electrical conductivity, good stability in both reducing and oxidizing atmospheres, and close coefficient of thermal expansion (CTE) match and good compatibility with other SoFC ceramic component.
