Activation of Cobalt Foil Catalysts for CO Hydrogenation
(Peer reviewed; Journal article, 2022)CO hydrogenation has been studied on cobalt foils as model catalysts for Fischer–Tropsch (FT) synthesis. The effect of pretreatment (number of calcinations and different reduction times) for cobalt foil catalysts at 220 ... -
Catalytic Oxidation of NO over LaCo1−xBxO3 (B = Mn, Ni) Perovskites for Nitric Acid Production
(Journal article; Peer reviewed, 2019)Abstract Nitric acid (HNO3) is an important building block in the chemical industry. Industrial production takes place via the Ostwald process, where oxidation of NO to NO2 is one of the three chemical steps. The reaction ... -
Ce- and Y-Modified Double-Layered Hydroxides as Catalysts for Dry Reforming of Methane: On the Effect of Yttrium Promotion
(Journal article; Peer reviewed, 2019)Ce- and Y-promoted double-layered hydroxides were synthesized and tested in dry reforming of methane (CH4/CO2 = 1/1). The characterization of the catalysts was performed using X-ray fluorescence (XRF), X-ray diffraction ... -
CO Oxidation over Alumina-Supported Copper Catalysts
(Peer reviewed; Journal article, 2022)CO oxidation, one of the most important chemical reactions, has been commonly studied in both academia and the industry. It is one good probe reaction in the fields of surface science and heterogeneous catalysis, by which ... -
Core-Shell Nanostructures of Graphene-Wrapped CdS Nanoparticles and TiO2 (CdS@G@TiO2): The Role of Graphene in Enhanced Photocatalytic H2 Generation
(Peer reviewed; Journal article, 2020)Aiming to achieve enhanced photocatalytic activity and stability toward the generation of H2 from water, we have synthesized noble metal-free core-shell nanoparticles of graphene (G)-wrapped CdS and TiO2 (CdS@G@TiO2) by a ... -
Effect of microwave drying, calcination and aging of Pt/Al2O3 on platinum dispersion
(Journal article; Peer reviewed, 2018)The effect of heating method employed for drying and calcination during the synthesis of 1 wt% Pt/Al2O3 catalyst was investigated. Conventional heating (CH) in resistive oven and microwave heating (MW) in single mode were ... -
Fischer-tropsch: Product selectivity-the fingerprint of synthetic fuels
(Journal article; Peer reviewed, 2019)The bulk of the products that were synthesized from Fischer–Tropsch synthesis (FTS) is a wide range (C1–C70+) of hydrocarbons, primarily straight-chained paraffins. Additional hydrocarbon products, which can also be a ... -
Investigation of C1+C1 coupling reactions in cobalt-catalyzed Fischer-Tropsch synthesis by a combined DFT and kinetic isotope study
(Journal article; Peer reviewed, 2019)Understanding the chain growth mechanism is of vital importance for the development of catalysts with enhanced selectivity towards long-chain products in cobalt-catalyzed Fischer-Tropsch synthesis. Herein, we discriminate ... -
Properties and Recyclability of Abandoned Fishing Net-Based Plastic Debris
(Peer reviewed; Journal article, 2022)Plastics in marine environments undergo molecular degradation via biocatalytic and photocatalytic mechanisms. Abandoned, lost, or discarded fishing gear (ALDFG) damages marine and coastal environments as well as plant and ... -
Significance of C3 Olefin to Paraffin Ratio in Cobalt Fischer–Tropsch Synthesis
(Peer reviewed; Journal article, 2020)The ratio between propene and propane (C3 o/p) during Fischer–Tropsch synthesis (FTS) has been analyzed based on both literature reports and experiments for five catalysts. The latter comprise four cobalt catalysts on ... -
The Effect of Potassium on Cobalt-Based Fischer– Tropsch Catalysts with Different Cobalt Particle Sizes
(Journal article; Peer reviewed, 2019)The effect of K on 20%Co/0.5%Re/γ-Al2O3 Fischer–Tropsch catalysts with two different cobalt particle sizes (small, in the range 6–7 nm and medium size, in the range 12–13 nm) was investigated. The catalyst with the smaller ... -
