The inaugural National Competition for Carbon Dioxide Capture, Conversion and Utilization Innovation ("Bloomag Cup") was successfully held on July 30, 2023 in Beijing. This competition was initiated by Professor Tianwei Tan and Prof. Yongqin Lv from Beijing University of Chemical Technology (BUCT), and jointly organized by BUCT and Chongqing University. The competition is slated for annual recurrence, with a rotational hosting arrangement involving various academic institutions. The ongoing competition underscores the primacy of pioneering and exploratory facets inherent to technological innovation. Its principal objective is to catalyze the development of foundational and cutting-edge technological competencies within the realm of CO capture, conversion, and utilization. The overarching goals encompass identifying promising technological breakthroughs, fostering emerging talent in scientific and technological innovation, facilitating high-quality sustainable economic growth within China, and actively contributing to global efforts towards peak carbon emissions and achieving sustainable development goals for humanity. This inaugural Bloomag Cup saw wide participation from students and researchers, generating fruitful discussions that advance the nascent field. It is hoped this competition will continue cultivating solutions that help mitigate anthropogenic climate change through innovative carbon dioxide technologies.

A comprehensive optimization of known prokaryotic autotrophic carbon dioxide (CO) fixation pathways is presented that evaluates all their possible variants under different environmental conditions. This was achieved through a computational methodology recently developed that considers the trade-offs between energy efficiency (yield) and growth rate, allowing us to evaluate candidate metabolic modifications for microbial conversions. The results revealed the superior configurations in terms of both yield (efficiency) and rate (driving force).

This perspective work examines the current advancements in integrated CO capture and electrochemical conversion technologies, comparing the emerging methods of (1) electrochemical reactive capture (eRCC) though amine- and (bi)carbonate-mediated processes and (2) direct (flue gas) adsorptive capture and conversion (ACC) with the conventional approach of sequential carbon capture and conversion (SCCC). We initially identified and discussed a range of cell-level technological bottlenecks inherent to eRCC and ACC including, but not limited to, mass transport limitations of reactive species, limitation of dimerization, impurity effects, inadequate generation of CO to sustain industrially relevant current densities, and catalyst instabilities with respect to some eRCC electrolytes, amongst others. We followed this with stepwise perspectives on whether these are considered intrinsic challenges of the technologies - otherwise recommendations were disclosed where appropriate.

The direct conversion of dinitrogen to nitrate is a dream reaction to combine the Haber-Bosch and Ostwald processes as well as steam reforming using electrochemistry in a single process. Regrettably, the corresponding nitrogen oxidation (NOR) reaction is hampered by a selectivity problem, since the oxygen evolution reaction (OER) is both thermodynamically and kinetically favored in the same potential range. This opens the search for the identification of active and selective NOR catalysts to enable nitrate production under anodic reaction conditions.

This review explores the behavior of low-concentration CO (LCC) in various energy media, such as solid adsorbents, liquid absorbents, and catalytic surfaces. It delves into the mechanisms of diffusion, adsorption, and catalytic reactions, while analyzing the potential applications and challenges of these properties in technologies like air separation, compressed gas energy storage, and CO catalytic conversion. Given the current lack of comprehensive analyses, especially those encompassing multiscale studies of LCC behavior, this review aims to provide a theoretical foundation and data support for optimizing CO capture, storage, and conversion technologies, as well as guidance for the development and application of new materials.

Selective coupling of C platform molecules to C olefins is a cornerstone for establishing a sustainable chemical industry based on nonpetroleum sources. Vinyl chloride (CHCl), one of the top commodity petrochemicals, is commercially produced from coal- or oil-derived C hydrocarbon (acetylene and ethylene) feedstocks with a high carbon footprint. Here, we report a C-based route for vinyl chloride synthesis via the selective oxidative coupling of methyl chloride.
