“…If pH > pK a , glucose is in the negatively charged form, but TiO 2 surface is negatively charged too (pH higher than the isoelectric point of TiO 2 , ca. pH = 6 [209]), limiting adsorption and, thus, H 2 evolution rate. Furthermore, different H 2 production rate was obtained with the two anomers α-and β-D-glucose.…”

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.

“…Although the basic tendencies of influencing of surfactants on property of water suspensions of titanium dioxide are known [19,20], no doubt, features of influencing of adsorption of TRITON X-100 and ATLAS G-3300 on them in a wide changing of range of medium pH and concentration of surfactants have caused scientific interest.…”

“…Functionalization by organic compounds may be used to increase the dispersibility in liquids and formation of stable colloidal solutions, but also to improve compatibility with solids, e.g., polymer matrices [1]. Physical properties of particles in suspensions strongly depend on charge distribution and ionic structure at the particle-solvent interface [2,3]. Aggregation of nanoparticles, as a spontaneous process, must be hindered to keep the system in the form of a stable transparent colloid.…”
