          Abstract

          Graphical abstract

          A surprisingly high CO 2-selectivity (95–99.6%) of single-phase ZnO in methanol and formaldehyde steam reforming, which helps in gaining enhanced understanding of the catalytic performance of the unsupported and supported intermetallic compound ZnPd, has been observed.

          Highlights

          ► ZnO is a CO 2-selective methanol steam reforming catalyst. ► ZnO selectively catalyzes formaldehyde via steam reforming to CO 2. ► A beneficial role of ZnO in oxidizing formyl-containing species is evident in ZnO supported systems.

          Abstract

          ZnO was tested as possible methanol and – since formaldehyde is one of the key intermediates in methanol conversion reactions – also as formaldehyde steam reforming catalyst. Catalytic experiments in a batch as well as a flow reactor resulted in highly selective steam reforming, though at low specific activities, of formaldehyde and methanol over ZnO toward CO 2 (selectivity of 95–99.6%). Comparison of the behavior of ZnPd near-surface intermetallic phases, unsupported intermetallic ZnPd and supported ZnPd/ZnO catalysts reveals that formaldehyde is formed from methanol in parallel with CO 2 on the former, while on unsupported intermetallic ZnPd and ZnO-supported ZnPd, it is efficiently reacted toward CO 2, thus, a beneficial role of ZnO in oxidizing formaldehyde-derived intermediates toward CO 2 is evident.
