Preparation of CO2 adsorbents and techno-economic analysis for CO2 capture and utilization
Adsorption is one promising technology because CO2 adsorbents can provide an opportunity to capture CO2 with lower energy consumption, good stability, non-volatility, etc. Many adsorbents such as carbonaceous adsorbents, microporous organic frameworks (MOFs), amorphous microporous/porous organic …

DEVELOPMENT OF NOVEL CATALYSTS AND PROCESSES FOR SUSTAINABLE HYDROGEN TECHNOLOGIES
This Ph.D. study advances hydrogen-related technologies to support decarbonization, focusing on key reactions like propane dehydrogenation (PDH), CO₂ methanation, dry reforming of methane (DRM), and COₓ-free catalytic methane decomposition (CDM). A core challenge in these processes is catalyst …

Non-noble metal nanocatalysts for the purification and reduction of carbon dioxide
… purification, and upgrading of carbon dioxide (CO2). The development of novel heterogeneous catalytic systems is essential to address many of the technological and economic challenges at hand. Nanostructures based on non-noble metals have been traditionally understudied due to their high …

Technoeconomic and mechanistic insights into the electroreduction of carbon dioxide to value added chemicals
… oil, and natural gas. However, the increased utilization of fossil fuels has come with a penalty: a rapid rise in the atmospheric carbon dioxide (CO2) levels, especially in the past few decades, with the daily average value crossing and staying above the 400 ppm mark in 2016 for the first time …

Developing durable electrodes for selective electroreduction of CO2 to value-added intermediates
… Specifically, rising excess carbon dioxide (CO2) emissions (over 14 Gt CO2 per year) has pushed the atmospheric CO2 concentration to over 400 ppm. This high atmospheric CO2 (and other greenhouse gases) concentration has been linked to rising global temperatures and climate change, both of …

Co-electrolysis of simulated coke oven gas using solid oxide electrolysis cell technology
… of 91.7 vol%, balanced mainly in carbon dioxide (CO2) and carbon monoxide (CO). Theoretically, this corresponds to a worldwide H2 production from COG of 87.6 Mt, which is in excess of the current global demand for H2 (70 Mt). This was achieved via combination of catalytic steam reforming of CH4 …

Economic and Environmental Assessment of an Integrated Carbon Capture and Utilization Pathway
… growth of global energy demand while mitigating CO2 emissions is an urgent challenge of this century. With the growing interest in carbon capture and conversion technologies, there is a growing need to assess the economic feasibility and environmental benefit of these technologies. While broad …

Salts as highly diverse porogens : functional ionic liquid-derived carbons and carbon-based composites for energy-related applications
… have in common that they are based on the utilization of ionic liquids, salts which are liquid below 100 °C, as precursors. Just recently, ionic liquids were shown to be versatile precursors for the generation of heteroatom-doped carbons since the liquid state and a negligible vapor …
