During the past decade, there has been increasing interest in the catalytic reforming of methane with carbon dioxide. This reaction is considered as more efficient use of natural gas (methane) but also in the context of possible utilization of carbon dioxide. As both CH4 and CO2 are greenhouse gases, this reaction has also important environmental implications. In this review, an emphasis was put on the recent papers, published in the period 1998-2001, which have not been reported in the comprehensive review of Bradford and Vannice. Some basic thermodynamic and kinetic information about the discussed reaction and CH4 and CO2 activation was recalled. Then different types of catalysts were reported, first of all focused on nickel and platinum group based catalysts. New approaches to the mechanisms of the reaction on catalysts Ni/ZrO2 and Ru/SiO2 and Ru/Al2O3 were shown. The major difficulty in practical realization of methane reforming with CO2 is thermodynamically favoured coke formation which deactivates the catalysts. The route leading to the improvement of this situation can be an addition of oxygen or water to the feed gas mixture or developing catalysts that minimize the rate of carbon deposition. The modification of the support, an application of bimetallic catalysts or another complex systems seem to be promising. Some of such systems were reported in the review. Among 112 references cited in this review, 72 were published in the period 1998-2001. Therefore, the authors hope that this contribution presents a useful and reasonable supplement to Bradford and Vannice work.
