Abstract:

The generation of high purity hydrogen by renewable, sustainable means is a crucial building block towards the realisation of a carbon-free energy economy. Proton exchange membrane water electrolysis (PEMWE) offers a promising route for the generation of clean hydrogen, using renewable energy, for both stationary and mobile energy storage applications, and as a feedstock for the chemical industry. As water electrolysis is an electrochemical redox reaction, cathodic hydrogen evolution cannot occur without an efficient, and rapid anodic oxygen evolution reaction (OER). While both iridium and rut

Abstract:

Vanadium and molybdenum oxide catalysts have been prepared on different Ti02 supports by a variety of methods. Solutions of VOC13, VO(O'Bu)3 and MoOC14 were used to graft VOX and MoOX monolayers onto the supports in a single treatment. The other methods were intended to produce more than one monolayer (i. e. aqueous impregnation and multiple treatments of VOC13 and VO(O1Bu)3 ). TPR and Raman spectroscopy showed the formation above the monolayer of a phase denoted as disordered vanadium oxide, which has the same reducibility as the monolayer species but which has a band in the Raman spectrum at

Manganese oxide catalysts supported on Al2O3, ZrO2, TiO2 and SiO2 supports were used to study the effect of support on ozone decomposition kinetics.

EXAFS spectra suggest that the manganese active centers on all of the surfaces were surrounded by five oxygen atoms. These metal centers were of a mononuclear ty

In this research project, heterogeneous catalysts of zirconium oxide were produced by impregnation. Zirconium oxide impregnation with sulfuric acid produced acidic solid catalysts. It was determined that impregnation and calcination at 550<sup>o</sup>C (SO<sub>4</sub>/ZrO<sub>2</sub>-550<sup>o</sup>C) produced the best catalyst for palmitic acid esterification with 10 wt % as the optimum concentration in esterificatio

Slurry temperature and calcination temperature are also very important parameters which affect the selectivity pattern of the products. This selectivity pattern was found to be further influenced by reaction temperature, pressure, GHSV

Abstract:

The solid acid catalyst of the Keggin-type 12-tungstophosphoric acid (H3PW12O40, HPW) is supported on partially reduced graphene oxide (PRGO) nanosheets for acid-catalyzed reactions. HPW is a new class of catalyst with a good thermal stability and high Bronsted acidity in order to replace common mineral acids. However, it has low specific surface area (1-5 m2/g). Therefore, the possibility of PRGO as a catalytic support for HPW is investigated due to its high surface area (2630 m2/g) and good thermal stability. The synthesis of HPW-GO catalyst is prepared using microwave and laser irradiation

Higher alcohols synthesized via CO hydrogenation reactions have been a topic of intense study both in industry and academia for over thirty years. A variety of transition metals and promoters have been used in catalysts for this reaction. MoS₂, in particular, is popular due to its low cost, resistance to sulfur poisoning, and ability to selectively produce higher alcohols over hydrocarbons. The bulk material has a rich history in hydrodesulfurization reactions (HDS), and as such, a great deal is known about the material's structure and reactivity.

Abstract:

The preferential oxidation of CO (CO-PROX) has been identified as one route of further reducing the trace amounts of CO (approx. 0.5 - 1 vol%) in the H2-rich reformate gas after the high- and low-temperature water-gas shift reactions. CO-PROX makes use of air to preferentially oxidise CO to CO₂, reducing the CO content to below 10 ppm while minimising the loss of H₂ to H₂O. In this study, a Co₃O₄/γ-Al₂O₃ model catalyst was investigated as a cheaper alternative to the widely used noble metal-based ones.

Abstract:

M.Tech. (Chemical Engineering)<br>There are a number of processes for the production of biodiesel. Homogenous catalysed processes are the most popular in large scale production due to short reaction times and less extreme reaction conditions. Despite this, homogenous catalysts have a number of disadvantages which include: high probability of soap formation in the presence of water and free fatty acids; they cannot be re-used since some of the catalyst is consumed during the reaction and the separation of the remaining catalyst from the product is difficult. In contrast, heterogeneous catalysts
