“…For example, understanding the interplay of the electrode reactions with mass and heat transport, the transport activity nexus, is crucial to leverage the full potential of the technology for electrode reactions other than the hydrogen evolution reaction. [132,133] O-SOE, which is particularly attractive for a wider adoption of CO (and synthesis gas) production from CO 2 (and water), has been demonstrated both at the stack and system levels [134,135] to outperform low-temperature electrolysis, in particular for the technical key performance indicators (faradaic efficiency, cell voltage, energy efficiency, and electric power consumption). H-SOE is at a lower TRL, but can still contribute to a CO 2 -neutral value chain by non-oxidative dehydrogenation of short-chain hydrocarbons.…”

The chemical industry must become carbon neutral by 2050, meaning that process-, energy-, and product-related CO 2 emissions from fossil sources are completely suppressed. This goal can only be reached by using renewable energy, secondary raw materials, or CO 2 as a carbon source. The latter can be done indirectly through the bioeconomy or directly by utilizing CO 2 from air or biogenic sources (integrated biorefinery). Until 2030, CO 2 waste from fossilbased processes can be utilized to curb fossil CO 2 emissions and reach the turning point of global fossil CO 2 emissions. A technology mix consisting of recycling technologies, white biotechnology, and carbon capture and utilization (CCU) technologies is needed to achieve the goal of carbon neutrality. In this context, CHEMampere contributes to the goal of carbon neutrality with electricity-based CCU technologies producing green chemicals from CO 2 , N 2 , O 2 , and H 2 O in a decentralized manner. This is an alternative to the e-Refinery concept, which needs huge capacities of water electrolysis for a centralized

“…For example, this point is perfectly illustrated by membrane electrode assemblies in polymer–electrolyte fuel cells, where functional carbon materials stand in direct contact with solid (ion-conducting polymer and Pt electrocatalysts), liquid (H 2 O), and gaseous (H 2 , O 2 , and H 2 O) phases. These functional carbons are required to perform a wide variety of tasks simultaneously, ensuring electrical contact, the dispersion and stability of the Pt catalyst, and the transport of reactants to and the removal of reaction products from the catalytically active sites. , …”

Can Temperature-Programmed Techniques Provide the Gold Standard for Carbon Surface Characterization?

Due to their chemical and thermal stability, electrical conductivity, and high specific surface areas, nanocarbons and porous carbon materials have found use in numerous key applications within the current transition of energy and raw-material sources. Since all these applications rely on multiphase interactions between the carbon surface and surrounding solid, liquid, or gaseous phases, carbon surface chemistry is elevated to a critical factor of influence. However, the characterization of carbon surface chemistry is notoriously complex, involving carbon defect sites and chemically similar heteroatom species in a wide range of different binding states and chemical environments. Due to this high degree of complexity, a comprehensive characterization of carbon surface species and reactivity is a major challenge for which there is no analytical “silver bullet” but is fundamental to the rational development of advanced functional carbon materials. In this context we would like to highlight the potential of temperature-programmed techniques (TPX) for carbon surface analytics, which benefit from widely available, easy-to-handle equipment and offer information on the identity, quantity, and reactivity of surface species. Hence, this article reviews the state of the art concerning temperature-programmed techniques for carbon surface characterization, focusing not only on the qualitative and quantitative analysis of carbon surface species but also on the unique ability of temperature-programmed methods to assess carbon surface reactivity. In this context, progress made so far in temperature-programmed desorption, temperature-programmed reduction, and temperature-programmed surface reactions is discussed, highlighting pitfalls and gaps in knowledge. Based on this foundation, strategies for the further development of temperature-programmed methods for carbon surface analysis are proposed, aiming to establish TPX as the future gold-standard in carbon surface characterization.
