“…energy purposes in fuel cells is a topic of large and growing interest [14]. Hydrogen is produced from various energy sources, stored, transported and used in industries, homes, automobiles, airplanes and factories or used as electricity generations, and will be used more and more if the research and development of it, is continued [10].…”

“…The interest on fuel cells has increased, however the main difficulty on hydrogen utilization is about production cost, in this context, a cheaper production alternative could make viable the hydrogen utilization in fuel cells [15]. The production of hydrogen as a fuel from a suitable carrier is a necessary step in light of the difficulties faced in hydrogen transport and storage [14].…”

Hydrogen is a promising alternative energy sources, hydrogen can be used in fuel cell applications to pro-ducing electrical energy and water as byproduct. Therefore, fuel cell is a simple application and environ-mentally friendly oriented technology. Recent years various methods have been conducted to produce hy-drogen. Those methods are derived from various sources such as methanol, ethanol, gasoline, hydrocarbons. This article presents a brief review a parameter process of that affects in autothermal reforming methanol use Cu-based catalysts for production of hydrogen. Copyright © 2012 BCREC UNDIP.

“…In this regard, methanol is a promising hydrogen carrier candidate for the future [5] mainly because it has high H to C ratio, low chemical energy bond [6] and can be produced either by reduction CO2 or from diverse bio-based resources [7]. 3 Methanol steam reforming (MSR) is accompanied with side-reactions such as: methanol decomposition (MD), water gas shift (WGS) and reversed water gas shift (RWGS) [8,9]. The extent of these processes depends on the feed composition, reaction conditions and the catalyst used.…”

The influence of the calcination atmosphere of ZnO precursor (Zn4(CO)3(OH)6·H2O) on the catalytic performance of a series of PdZn/ZnO catalysts was studied for production of H2 via low temperature (180 • C) direct methanol steam reforming (low temperature-MSR). The catalytic activity and selectivity of PdZn/ZnO were found to be strongly influenced by the calcination atmosphere of ZnO precursor and increased from oxidizing to reducing atmosphere, following the order (O2 < air < N2 < H2). As a result, a very active catalyst was obtained by simply supporting Pd on ZnO calcined in H2. Further evidence from XPS and TPR analysis indicated that calcination in reducing atmosphere gave rise to a significant increase in the concentration of oxygen vacancies on the surface of ZnO support. Thus, the superb performance of the best catalyst was attributed to the defect chemistry of ZnO support; mainly to the amount of oxygen vacancies present in the interface region, which act as additional active sites for water adsorption and subsequent activation. In addition, the formation of CO was drastically suppressed by replenishment of oxygen vacancies on ZnO support. Thus, it is clear that the abundance of specific active sites on PdZn/ZnO catalyst is strongly influenced by the preparation route of the ZnO support. Additionally, the PdZn alloy was discovered to be unstable under prolonged exposure to CO atmosphere and the stability test under methanol steam reforming conditions showed a 24% drop in conversion over 48 h testing period. This phenomena can have detrimental effect on the performance of this type of catalytic systems in continuous prolonged duty cycle time on-stream.

“…However, in order to improve their catalytic activity, the addition of promoters (e. g., Zr, Zn and Mn) and the preparation method have been under study (Sá et al 2010). MSR has been studied over Cu-Zn based catalysts at temperatures lower than 573 K (Agrell, Birgersson, and Boutonnet 2002;Bichon et al 2007; Purnama et al 2004;Sá et al 2010;Turco et al 2007; Wu et al 2009). Zn improved the metal dispersion and reducibility of Cu 2 + species, generating a positive effect on catalytic activity.…”

This work reports the preparation of Cu-Zn and Au/TiO2 catalysts on anodized aluminum monoliths (AAM). The structured catalysts were studied for the generation of H2 by methanol steam reforming (MSR) and its purification by preferential oxidation of CO (CO-PrOx). Initially, it was possible to generate a surface with whiskers and larger surface area by hydrothermal treatment of the AAM. Subsequently, the structured catalysts were synthesized by incipient wetness impregnation (IWI) and hydrothermal synthesis (HS). IWI synthesis allowed for the deposition of a larger amount of catalytic material than HS, with very good adhesion. The TiO2-IWI structured catalyst presented a homogeneous catalytic coating, with the presence of agglomerated particles. On the other hand, Cu-Zn-IWI showed good dispersion of the deposited particles with a homogeneous surface coating. EDX analysis corroborated the presence of Ti, Cu and Zn in all the catalytic surfaces. The incorporation of Au over TiO2-IWI structured catalysts was successfully performed by IWI using a colloidal solution of gold nanoparticles. MSR was studied over the developed metallic monoliths functionalized with Cu-Zn by the IWI method. The samples showed promising results in terms of activity, selectivity, and stability. Both diluted and concentrated methanol + water feeds were assayed. Complete methanol conversion was achieved for the diluted feed. Maximum methanol conversions of 55 % with 60 % H2 yield were measured when the concentrated feed was selected. Promising results were also achieved for the Au-based structured catalysts in the CO-PrOx in an H2-rich atmosphere. Although CO conversions of approximately 60 % were achieved, operating with higher catalyst loadings would be recommended to reach the high CO conversions required for PrOx catalysts.
