Layered and poriferous (Al,C)-Ta2O5 mesocrystals supported CdS quantum dots for high-efficiency photodegradation of organic contaminants

Heterojunction engineering has shown great potential in the field of photocatalysis to deal with environmental pollutants. The design and synthesis of heterojunction photocatalysts with high efficiency and stability still face great challenges. In this work, a novel CdS quantum dots (QDs) decorated 3D Bi2O2CO3 hierarchical nanoflower heterojunction photocatalyst (Bi2O2CO3/CdS QDs) was synthesized to investigate the photocatalytic Rhodamine B (RhB) degradation performance. CdS QDs were evenly distributed on the surface of the Bi2O2CO3 nanoflower. Bi2O2CO3/CdS QDs showed significantly enhanced photocatalytic RhB degradation performance compared with pristine Bi2O2CO3 and CdS QDs. The enhanced photocatalytic performance was attributed to the synergistic effect of hierarchical structure and heterojunction, which greatly increased the active sites of the reaction and the photogenerated carriers transfer.

Sensitized Solar Cells

Quantum dot sensitized solar cell (QDSSC) has a potential high efficiency as the third generation solar cell, on account of the excellent performance of quantum dots. CdS is one of the most widely used quantum dot of QDSSCs, hence the optimization of its preparation process is extremely important. CdS quantum dots prepared in aqueous or alcohol on TiO2 film by successive ionic layer adsorption and reaction (SILAR) method are investigated and alcohol is found to be better than water as the precursor solvent.

Titanium Substrates

Nanocrystalline TiO2films were fabricated on titanium substrates by compression method. The CdS quantum dots (QDs) were assembled onto the compressed TiO2layers, which serve as sensitizers. A maximum power conversion efficiency of 4.49% is achieved under 100 mW/cm2illumination. In this paper, we find that the compression can help increase the efficiency of the cell by increasing the absorption of the CdS QDs and improving the transportation of photogenerated electrons.
