Carbon nanotubes grown perpendicularly on a silicon substrate were used as supports of fine platinum particles. Activity for catalytic combustion of hydrogen on the catalyst sheets was evaluated rapidly by the use of infrared imaging thermography. The thermographic image of the catalysts during hydrogen combustion reveals that platinum contents and conditions in preparation of catalysts, such as heat treatment temperatures or solvents used, affects the catalytic activity. The infrared thermography has therefore been shown to be a technique in evaluating catalytic activity.
