The electrochemical conversion of carbon dioxide into low carbon fuels is a very convenient way of reducing the concentration of atmospheric CO2, which is the main cause of global warming. CO is known to be the most common and profitable product of CO2 reduction due to its low energy requirement and reaction simplicity. However, the viability of the process still depends on affordable and efficient catalysts. In this review, an overview is provided on recent advances in developing highly efficient heterogeneous catalysts for the selective electroreduction of CO2 to CO, particularly considering the results of mechanistic investigations and the fulfillment of the basic catalytic requirements. Recent progress in the heterogeneous electrocatalysts is reviewed in a concise manner as much as possible by examining what is achieved from the different combinations of transition metals with a considerable variety of supporting materials such as metal-organic-frameworks, graphene-like carbonaceous materials, nitrogen-doped carbons, and other new-generation supports. The review also includes the comparison of the electrocatalysts used for the selective reduction of CO2 to CO in terms of catalytic efficiency and addresses the current challenges which need to be considered in designing future research works in the field.

Simulating CO2 sequestration in a depleted gas reservoir Özkılıç, Öke İsmet; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2005) Carbon dioxide is one of the greenhouse gases which have strong impacts on the environment and its amount in the atmosphere is far beyond to be ignored. Carbon dioxide levels are projected to be reduced by sequestering it directly to the underground. High amounts of carbon dioxide can be safely stored in underground media for very long time periods. Storage in depleted gas reservoirs provides an option for sequestering carbon dioxide. In 2002, production of Kuzey Marmara gas reservoir has been stopped due t...
Modelling of carbon sink capacity of the Black Sea Cengiz, Yelis; Yılmaz, Ayşen; Yücel, İsmail; Department of Earth System Science (2016) The concentration of carbon dioxide in the atmosphere is constantly increasing due to human activities and results in global warming. Since Industrial Revolution 30 and 25 percentages of the anthropogenic atmospheric carbon dioxide are taken up by the forests and by the oceans respectively. Carbon dioxide is rising faster than biosphere can tolerate and the rest of the carbon dioxide which can not be hold, continues to accumulate and causes further heating of the atmosphere. The carbon sink capacity of the ...
Cap rock integrity in CO₂ storage Dalkhaa, Chantsalmaa; Okandan, Ender; Department of Petroleum and Natural Gas Engineering (2010) One way to reduce the amount of CO2 in the atmosphere for the mitigation of climate change is to capture the CO2 and inject it into geological formations. The most important public concern about carbon capture and storage (CCS) is whether stored CO2 will leak into groundwater sources and finally into the atmosphere. To prevent the leakage, the possible leakage paths and the mechanisms triggering the paths must be examined and identified. It is known that the leakage paths can be due to CO2 - rock interactio...
Modeling and design of a non-thermal plasma reactor for CO2 dissociation Ahmed, Humayun; Taylan, Onur; Sustainable Environment and Energy Systems (2017-1) The requirement of energy constantly increases with time, and one of the major sources of energy is fossil fuels which release carbon dioxide upon combustion. Environmentally, CO2 is a greenhouse gas which has had a tremendous impact on the Earth’s climate over the last few decades and the urges serious mitigation methods for the long-term sustainability of the Earth’s climate and ecosystem. One mitigation method is the dissociation of CO2 to produce synthesis gas which can be used to produce alternative hy...
Geochemical characterization of geothermal systems in Turkey as natural analogues for geological storage of Co2/ Elidemir, Sanem; Güleç, Nilgün Türkan; Department of Geological Engineering (2014) To mitigate the unfavourable effect of CO2 emission on global warming and climate change, geological storage of CO2 is currently regarded to be one of the major strategies. Deep saline formations constitute one of the alternative reservoirs for hosting the injected CO2 and the information about the behaviour of these reservoirs is provided via the studies of natural analogues. This thesis is concerned with the geothermal systems of Turkey as natural analogues for CO2 storage sites and the evaluation of thei...
