“…PR is also thermodynamically more feasible than WS [10]. After a pioneering study in 1980 [11], the attention was more recently focused mostly on the PR of methanol, the simplest molecule, and a few examples of PR of compounds really obtainable from biomass can be found, for example, ethanol, glycerol [12][13][14], glucose, sucrose [14], starch and wood [11], and sewage sludge [15]. Glucose and cellulose were also processed with homogeneous catalytic processes [16].…”

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.

“…With the increasing production of biodiesel, the production of glycerol has increased as well, while the needs of glycerol is very limited. It will decrease the economic side and can be a waste of biodiesel plant and also increase production costs (Daskalaki, 2008).…”

The purpose of this research was to study pyrolysis of glycerol to produce hydrogen using microwave. The use of microwave aimed to produce high temperatures, because pyrolysis require high temperature.The effect of kind of catalyst and microwave power were studied. The catalyst was activated carbon and Ni/HZSM-5.The catalyst of activated carbon was ready to use, whereas Ni/HZSM-5 catalyst was obtained by ion exchange from Na-ZSM-5 with NH 4 Cl and then HZSM-5 was impregnated with metal solution of Ni (NO 3 ) 2 .6 H 2 O. Experiments were conducted by mixing catalyst in the reactor together with glycerol solution of 10% (weight percent) as much as 100 ml. Reactor was made from pyrex and mounted on microwave equipped with a thermocouple. And then, reactor was heated on power of 400-700 Watt during thirty minutes. The reaction produced gases and liquid to be analyzed by chromatography gas.The conclusion stated that microwave could pyrolysis glycerol into hydrogen. By product of this reaction were methanol, allyl alcohol, acrolein and unidentified products. The difference of catalyst produced different product as well. The pyrolysis of glycerol using activated carbon produced conversion of 60 %, while using catalysts Ni/HZSM-5 obtained conversion of 87 %. The reaction produced hydrogen gases was relatively small for both of catalysts that is minimum of 0,59% and maximum of 0,88%.

“…As a consequence, it is very crucial to promote new alternative energy that is renewable and environmental friendly. Hydrogen produced by photocatalytic reaction over TiO 2 in ambient condition from glycerol-water solution is a potential candidate, as it is a renewable, clean energy, and low cost compared to traditional technology [1,2,3]. Huge quantities of biomass-derived waste such as glycerol solution can be considered as interesting renewable and sustainable source for producing H 2 [2,3] .…”

Abstract. The sonication aided anodization in the TiO2 Nanotube Arrays (TNTA) formation and its performance for photocatalytic hydrogen generation from glycerol-water solution (10 v%) has been examined. TNTA were prepared by anodization of Ti foil at 30 V, 50 oC with glycerol containing fluoride as an electrolyte solution. The anatase phase was obtained by annealing of amorphous TNTA at 500 oC under H2 in Ar atmosphere for 3 h. TNTA have average tube's lengths and inner diameter approximately in the range of 0.5-1.5 μm and 70-84 nm respectively, and a comparable tube wall thickness of 14-20 nm was also observed. The elemental composition of TNTA observed are Ti, O, C, N, and F. In the range of 10 -60 min anodization process, it was found that the average inner diameters and length of the tubes increase as anodization time increased. The photocatalytic H2 generation test indicated that H2 produced was found to depend on the tube dimension. Among the TNTA obtained, TNTA-U60 with 1.46 µm tube length showed the highest hydrogen production (47,22 mmol/m2 photocatalyst).
