Photocatalytic Lithography Based on Photocatalytic Remote Oxidation
Journal of Photopolymer Science and Technology, 2007 Photocatalytic lithography is a method for surface patterning based on photocatalytic remote oxidation. A TiO2-coated photomask is faced with a surface to be patterned, and irradiated with UV light. If a glass plate modified with alkyl chains is used, hydrophilic/hydrophobic patterns can be obtained.

Photocatalytic Thermodynamic Efficiency Factors. Practical Limits in Photocatalytic Reactors
Industrial & Engineering Chemistry Research, 2010 The photocatalytic thermodynamic efficiency factor (PTEF) is a parameter that can be used in photocatalytic reactors to establish photon energy utilization as the ratio of the energy used to generate OH• free radicals and the energy absorbed by the TiO2 photocatalyst. The PTEF evaluation requires the assessment of the total rate of OH• free radicals at

Photocatalytic Lithography [PDF]
Applied Sciences, 2019 Patterning, the controlled formation of ordered surface features with different physico-chemical properties, is a cornerstone of contemporary micro- and nanofabrication. In this context, lithographic approaches owe their wide success to their versatility and their relative ease of implementation and scalability.
