Photocatalytic conversion of methane
Chemical Society Reviews, 2008Various efforts have been carried out to convert methane to more useful chemicals and hydrogen. However, due to its high stability, high energy is usually consumed for its conversion, which still remains as a problem to be solved. Recently, photocatalysis has been proposed to be one of the answers to break the thermodynamic barrier.

Photocatalytic Reduction in Microreactors
Chemistry Letters, 2006Abstract Photocatalytic reduction of benzaldehyde and nitrotoluene in microspace was investigated by using a microreactor with immobilized titanium dioxide. Advantages of a photocatalytic microreaction system which has a remarkably large surface-to-volume ratio have been examined.

Photocatalytic oxidation of sulfamethazine
Chemosphere, 2005The photocatalytic degradation of sulfamethazine (SMT), a sulfonamide drug, has been investigated in aqueous heterogeneous solutions containing n-type oxide semiconductors as photocatalysts. The disappearance of the organic molecule follows approximately a pseudo-first-order kinetics according to the Langmuir-Hinshelwood model.

Photocatalytic hydrogen production
Chemical Communications, 2011The efficient storage of solar energy in chemical fuels, such as hydrogen, is essential for the large-scale utilisation of solar energy systems. Recent advances in the photocatalytic production of H(2) are highlighted. Two general approaches for the photocatalytic hydrogen generation by homogeneous catalysts are considered: HX (X = Cl, Br) splitting ...

Photocatalytic oxidation of triclosan
Chemosphere, 2006In the spring of 2003, there was an outbreak of the severe respiratory syndrome (SARS) in Hong Kong. Health concerns have thus triggered an increased and predominant use of various types of household cleansing agents such as triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol).
