Toward the design of asymmetric photocatalytic membranes for hydrogen production: Preparation of TiO2-based membranes and their properties

“…The importance of optimizing catalyst exposure in form of films has been highlighted and, interestingly, the quantum yield and the energy conversion efficiency have been provided. A stable photoactive layer based on TiO 2 over a porous polymer membrane has been proposed [179]. The PR of ethanol was investigated under UV light irradiation.…”

This paper focuses on the application of photocatalysis to hydrogen production from organic substrates. This process, usually called photoreforming, makes use of semiconductors to promote redox reactions, namely, the oxidation of organic molecules and the reduction of H + to H 2 . This may be an interesting and fully sustainable way to produce this interesting fuel, provided that materials efficiency becomes sufficient and solar light can be effectively harvested. After a first introduction to the key features of the photoreforming process, the attention will be directed to the needs for materials development correlated to the existing knowledge on reaction mechanisms. Examples are then given on the photoreforming of alcohols, the most studied topic, especially in the case of methanol and carbohydrates. Finally, some examples of more complex but more interesting substrates, such as waste solutions, are proposed.

“…H 2 production from an H 2 O source attracts noteworthy attention from researchers working to convert solar energy into chemical energy for fuel (Brouwer, 2010;Kothari, Tyagi, & Pathak, 2010;Kudo, 2007;Tsydenov, Parmon, & Vorontsov, 2012). After Fujishima and Honda (1972), various studies on the photocatalytic H 2 development from H 2 O have been actively carried out.…”

“…After Fujishima and Honda (1972), various studies on the photocatalytic H 2 development from H 2 O have been actively carried out. Currently, there are many photocatalysts for H 2 production under UV and visible light (Brouwer, 2010;Kothari et al, 2010;Kudo, 2007;Leung et al, 2010;Tsydenov et al, 2012).
