How does a catalyst influence plasma behavior? What is the true role of a catalyst in a plasma environment? The observed synergies in plasma–catalysis processes have been usually attributed to conventional surface catalytic interactions. However, recent studies demonstrate that metallic catalysts may induce alterations in plasma behavior that substantially influence the overall process efficiency. This work reviews the latest advances in the field, proposing the term Plasma-Catalysis Promoter (PCP) to designate compounds that facilitate reactions not only at the catalyst surface but also within the plasma phase. It also highlights that advancing in the field requires a holistic approach capable of unraveling the multifunctional role of PCPs in plasma–catalysis processes.

Converting carbon dioxide into useful products offers a pathway to reduce CO2 emissions and an opportunity to transform renewable energy into energy carriers and/or high-value products. Unlike traditional thermal chemical technologies, non-thermal plasma CO2 conversion processes are well suited to coupling to renewable energy sources. However, the technology readiness level of such plasma processes is low, and a significant gap between existing fundamental research and industrial application remains. After briefly summarising the available non-thermal plasma technologies for CO2 conversion, criteria for successful industrialisation are considered, and recent progress towards considering and meeting the technical and economic requirements is analysed. The needs identified include using consistent energy efficiency calculations that consider losses in the power supply and elsewhere, improved reactor design for plasma catalytic processes, detailed techno-economic analyses, and studies of the integration of individual plasma reactors into a modularised system and a complete chemical process.

Bayesian optimization (BO) is a powerful technology for optimizing noisy, expensive-to-evaluate black-box functions, with a broad range of real-world applications in science, engineering, economics, manufacturing, and beyond. In this paper, we provide an overview of recent developments, challenges, and opportunities in BO for design of next-generation process systems. After describing several motivating applications, we discuss how advanced BO methods have been developed to more efficiently tackle important problems in these applications. We conclude the paper with a summary of challenges and opportunities related to improving the quality of the probabilistic model, the choice of internal optimization procedure used to select the next sample point, and the exploitation of problem structure to improve sample efficiency.

The depletion of fossil fuels and increasing demand on renewable biofuels, particularly enhancing energy security through sustainable biomass sources in catalytic activities. Heterogeneous catalysts are pivotal in advancing sustainable biofuel production by enhancing yield and reducing costs. Metal oxides are widely used as catalysts due to their active sites, high thermal and chemical stability. However, unsupported metal oxides often result in low yield, requiring large amounts of catalyst and long reaction times to achieve high biofuel production. Thus, it has attracted attention toward sustainable porous carbon supports to resolve the shortcomings. The porous carbon is gaining prominence as a sustainable catalyst support due to its renewability, cost-effectiveness, abundance, versatile surface functionalities, tuneable porosity, high surface area, and improved accessibility for reactants. This review explores the roles of sustainable porous carbons, including biochar, activated carbon, graphene-based materials, and carbon nitride, showcasing their distinctive properties in specific catalytic reactions. It encompasses the characteristics of porous carbon supports, such as hierarchical micro-mesoporous structure, pore distribution, pore size, specific surface area, interaction with active metals, in assisting the catalytic active sites for macromolecules cracking, aromatization, deoxygenation, and so forth. Despite the promising advancements, several challenges remain, including the need for cost-effective synthesis methods and long-term stability of catalysts. Ultimately, maximizing the potential of porous carbon as catalysts support is essential for advancing research in biofuel production.

This mini-review summarizes the chemical and physical characteristics of the furan ring, serving as a fundamental basis for understanding furan-based polymers. Two significant categories of furan-based polymers are examined: polyamide and polyurethane. The synthesis of furan-based nylon and polyurethane encounters challenges related to chain growth and high-temperature breakdown, which considerably limits the molecular weight of the final products. The potential solutions may require the integration of catalysis optimization, step polymerization, and polymerization parameters, among others. Another problem is that prospective research directions must be meticulously assessed about the incremental value of the furan ring to the current polymers. The bio-derived characteristics of the furan ring do not guarantee its substitution with benzene or an aliphatic segment. The inherent characteristics of the furan ring, such as elevated glass transition temperature, robust hydrogen bonding, and hydrophilicity, should serve as guiding principles in the design of furan-based polymers.

The pursuit of sustainable energy solutions has driven significant research into oxygen reduction reaction (ORR) catalysts. metal–organic framework (MOF)-derived transition metal–nitrogen–carbon (TM-N-C) catalysts emerge as a promising alternative to platinum due to their abundance, high surface area, and potential for single-atom catalyst formation. However, challenges related to intrinsic activity and durability hinder their widespread adoption. This mini-review highlights current advancements in MOF-derived TM-N-C catalyst development, including strategies to modulate electronic properties, create open pore structures, and introduce supportive materials. These approaches aim to enhance both activity and stability for proton exchange membrane fuel cell applications. The recent works with highest proton exchange membrane fuel cell performance and stability will be highlighted. Future research direction is proposed to achieve improved sustainability and optimal performance in various fuel cell environments.

An overview is given of major recent advancements in cold plasma-based water treatment, with specific focus on the degradation mechanisms of organic pollutants. Mechanistic insight is indeed a powerful tool for process optimization considering the treatment duration, its products, and energy costs as it provides guidelines for the design of optimized reactors and the selection of best experimental conditions. The cases considered emphasize the importance of matching the plasma composition in terms of reactive species with the reactivity of the target pollutant(s), and of identifying and understanding the reciprocal effects of different pollutants as well as those of complex aqueous matrices. Harnessing the chemistry activated by the plasma to achieve the desired goal is the key to treatment success. A general strategy is outlined for designing the best plasma experimental set-up and for predicting possible byproducts.

Shifting from rare and precious metal catalysts in photochemical systems, such as ruthenium and iridium, to abundant and sustainable ones is still challenging. Copper and iron are fascinating, given their relative abundance and economic advantage. While the conception of copper and iron luminophores for the application in catalysis is faced with the undesirable rapid deactivation of photoactive states, making intermolecular redox exchange inefficient, the harnessing of copper and iron's propensity to perform fast ligand exchange and accommodation of radical intermediates enabled their successful implementation in photocatalysis. This review underscores the rapid growth of copper and iron in photocatalysis as green and sustainable alternatives, highlighting the unique catalytic features they offer.
