Special Issue Information

Dear Colleagues,

Hydrogen has been actively used in large-scale industrial processes for several decades, including oil-refining processes for purifying heavy hydrocarbons into lighter hydrocarbons, hydrotreatments to remove impurities such as acidic components, ammonia production using the Haber–Bosch process, methanol production, and steel and glass treatment processes. Moreover, hydrogen has emerged as a new energy vector beyond its usual role as an industrial feedstock, and there are expanding applications for hydrogen to be used in many other fields, such as transportation or power generation. Currently, steam reforming of fossil fuels such as natural gas, LPG, or naphtha is the most economic and thus most common process for hydrogen generation and serves 95% of the world’s hydrogen demand. Although the current hydrogen production is almost entirely performed by fossil fuel reforming, more environmentally friendly pathways are proposed in the medium and long term. As an alternative to fossil fuels, biomass can also be used for steam reforming.

The aim of this Special Issue is to provide a platform for new knowledge associated with hydrogen production in steam reforming processes. Although these processes are far from new, research shows that there is still plenty of room for their improvement. Therefore, both review and original research articles focused on the recent advances in the development of heterogeneous catalysts for steam reforming of both renewable and nonrenewable resources, including the synthesis, characterization, and application of new catalysts for hydrogen production, studies on the activity and stability of the developed catalysts evaluated by the conversion of the substrate, yield/selectivity of products or turnover frequency (TOF) under steam reforming reaction conditions, and the mechanisms and kinetic details of steam reforming reactions are welcomed.

In this study, ZnFe2O4 and ZnO-ZnFe2O4 catalysts were prepared using the glycine–nitrate process (GNP). The prepared ZnFe2O4 and ZnO-ZnFe2O4 catalyst powders were characterized using a scanning electron microscope, transmission electron microscope, XRD diffraction studies, and selected area diffraction pattern studies. In addition, the specific surface area was measured using a Brunauer–Emmett–Teller specific surface area analysis. The hydrogen reduction in different temperature ranges was analyzed using the H2 temperature-programmed reduction technique. The specific surface area of the ZnFe2O4 was 5.66 m2/g, and the specific surface area of the ZnO-ZnFe2O4 was 8.20 m2/g at a G/N ratio of 1.5 and at a G/N ratio of 1.7, respectively. The specific surface area of the ZnFe2O4 was 6.03 m2/g, and the specific surface area of the ZnO-ZnFe2O4 was 11.67 m2/g. The ZnFe2O4 and ZnO-ZnFe2O4 were found to have the best catalytic effect at 500 °C. In particular, the highest H2 generation rate of the ZnO-ZnFe2O4 (GN = 1.7) at 500 °C was 7745 mL STP min−1 g-cat−1. Moreover, the ZnO-ZnFe2 O4 catalyst demonstrated good H2 selectivity and stability during the process of steam reforming methanol. Therefore, the ZnO-ZnFe2O4 catalyst powder exhibited high catalytic activity due to the good dispersibility of the ZnO, which increased the specific surface area of the catalyst. In the future, the catalyst can be applied to the steam reforming of methanol for industrial purposes. Full article
