Abstract: A growing interest in hydrogen use has been observed due to its environmentally friendlycharacteristics. However, the current methods of hydrogen production from natural gas are based on steammethane reforming, partial oxidation, and autothermal reforming. These processes produce a mixture ofhydrogen and carbon oxides and after water-gas shift reactions, in order to increase the production ofhydrogen, a large amount of CO2 is generated and possibly released in the atmosphere. In this context, thecatalytic methane decomposition has been receiving attention as an alternative route to the production ofCOx-free hydrogen. It has been reported that the appropriate group of catalysts and reactors can lead to aviable process. Current investigations attempt to increase the yield of hydrogen. The present work aims toevaluate the processes currently used for that and to present the preliminary results obtained with cobaltcatalysts for methane decomposition. A comparison between the conventional processes and the suggestedones is made, and the major advantages in the use of methane decomposition are presented.

The present study investigates a process for the selective production of hydrogen from the catalytic decomposition of formic acid in the presence of iridium and iridium–palladium nanoparticles under various conditions. It was found that a loading of 1 wt.% of 2% palladium in the presence of 1% iridium over activated charcoal led to a 43% conversion of formic acid to hydrogen at room temperature after 4 h. Increasing the temperature to 60 °C led to further decomposition and an improvement in conversion yield to 63%. Dilution of formic acid from 0.5 to 0.2 M improved the decomposition, reaching conversion to 81%. The reported process could potentially be used in commercial applications.
