Traditional analysis of reactions catalyzed by supported metals involves the structure of the metallic particles. However, we report here that for the class of nanostructured gold- or platinum-cerium oxide catalysts, which are active for the water-gas shift reaction, metal nanoparticles do not participate in the reaction. Nonmetallic gold or platinum species strongly associated with surface cer...

The conversion of carbon sources such as coal and methane into liquid fuels, methanol and alkanes, the latter via the Fisher-Tropsch process, requires careful control of the H2/CO ratio in synthesis gas. 1 The control is achieved in industry by the water-gas shift reaction. (Figure 1). 2 The study of carbon monoxide dehydrogenase (CODH) enzymes is significant to the water gas shift reaction bec...

Pt/MoOx/TiO2 shows excellent catalytic performance for the reverse water-gas shift reaction at 250 °C via Mars–van Krevelen mechanism.

Correction for ‘Surface reaction kinetics of the methanol synthesis and water gas shift on Cu/ZnO/Al2O3’ by Bruno Lacerda de Oliveira Campos et al., React. Chem. Eng., 2021, 6, 868–887; DOI: 10.1039/D1RE00040C

Nano-sized iron-based catalyst was prepared by the micro-emulsion method. The composition of the final nano-sized iron catalyst, in term of the atomic ratio contains: 100Fe/4Cu/2Ce. Experimental techniques of XRD, BET, TEM and TPR were used to study the phase, structure and morphology of the catalyst. Fischer-Tropsch Synthesis (FTS) reaction test was performed in a fixed bed reactor at pressure...

A combined catalyst and sorbent was developed for reacting CO with steam to produce H2 in a single reaction stage at 600 °C by employing the water gas shift (WGS) reaction. The combined material was in the form of spherical pellets where each pellet consisted of a CaO core for absorbing byproduct CO2 surrounded by a porous shell of Al2O3 which supported a Ni catalyst. The best results were achi...

One of the main reactions that can be used to reduce greenhouse gases emissions is Reverse Water Gas Shift (RWGS) reaction. Through this reaction CO2 is converted to CO to produce beneficial chemicals such as methanol. In this paper Mo/Al2O3 catalyst was prepared and then promoted with Ni ions through impregnation method to produce Ni-Mo/Al2O3 catalyst. The structures of the catalysts were stud...
