| The Role of Chemical Engineering in Climate Change Mitigation | Climate change is one of the most significant global challenges of our time, with far-reaching consequences for ecosystems, economies, and human health. Chemical engineering plays a crucial role in mitigating the effects of climate change by developing and optimizing technologies that reduce greenhouse gas emissions, promote energy efficiency, and facilitate the transition to renewable energy sources. This article explores the various ways in which chemical engineering contributes to climate change mitigation, focusing on advancements in carbon capture, renewable energy production, energy storage, and sustainable industrial processes. The paper also discusses the challenges faced by chemical engineers in scaling up these technologies and the role of innovation in addressing climate change. | 10.71465/ajcce171 | 31.10.2020 | CO2 conversion | |

| Dynamic Restructuring of ZrO2–Cu Interfaces Under CO2 Hydrogenation Conditions | The catalytic performance of inverse oxide–metal systems is strongly influenced by their structural dynamics under reaction conditions. In this study, ab initio molecular dynamics simulations were carried out to investigate temperature-induced restructuring at ZrO2-on-Cu interfaces between 450 and 600 K. The simulations reveal reversible Zr–O bond rearrangements that generate transient low-coordination Zr sites with enhanced Lewis acidity. These dynamically formed sites lower the CO2 activation barrier by up to 0.31 eV compared with static interface models. Time-averaged free energy profiles indicate a 2.7-fold increase in predicted methanol formation rates when dynamic effects are included. In contrast, simulations constrained to static geometries systematically underestimate catalytic activity. The results demonstrate that interface flexibility plays a decisive role in stabilizing key intermediates and should be explicitly considered when modeling inverse catalysts for CO2 hydrogenation | 10.71465/ajcce3626 | 28.02.2026 | CO2 conversion | |
| Visible‐Light‐Driven Palladium‐Catalyzed Carbonylative Cyclization to Quinolin‐2( 1 H )‐ones Using Silane as Hydrogen Donor | Comprehensive Summary Quinolin‐2(1 H )‐ones represent a class of privileged nitrogen‐containing heterocycles widely found in natural products, pharmaceuticals, and functional materials. Traditional synthetic methods often rely on harsh conditions such as high temperatures, high CO pressures, or stoichiometric oxidants, which limit their functional group tolerance and sustainability. In this work, we report a visible‐light‐driven palladium‐catalyzed carbonylative cyclization of o ‐alkynylanilines for the efficient synthesis of quinolin‐2(1 H )‐ones under mild and oxidant‐free conditions. The key innovation lies in the use of triphenylsilane (Ph₃SiH) as a mild hydrogen atom donor, enabling C–H activation and CO incorporation at ambient pressure and room temperature. The cooperative Pd(TFA)₂/Ir(ppy)₃ catalytic system, combined with TBAB as an additive, delivers the desired products in good to excellent yields with broad functional group tolerance. The protocol is applicable to a variety of substituted o ‐alkynylanilines, including those bearing electron‐donating, electron‐withdrawing, and disubstituted groups, as well as heteroaryl and cycloalkyl N ‐substituents. Notably, the method also extends to the synthesis of coumarin derivatives from o ‐alkynylphenols, further demonstrating its versatility. Late‐stage functionalization of bioactive aldehydes, such as vanillin, cinnamaldehyde, and (–)‐perillaldehyde, was successfully achieved, underscoring the potential for drug discovery applications. Gram‐scale synthesis and further transformations, including chlorination, reductive functionalization, and photocatalytic methylation, highlight the synthetic utility of this approach. Mechanistic studies, including deuterium labeling, radical trapping, and fluorescence quenching, support a radical pathway involving photoredox‐generated radical cations and Pd‐hydride intermediates. This work provides a sustainable and practical platform for the construction of valuable N ‐heterocycles and offers new insights into silane‐mediated hydrogen transfer in dual catalytic systems. | 10.1002/cjoc.70558 | 02.04.2026 | CO conversion | |

| Methanation of Syngas in a Three‐Stage Serial Reactor System Using a Set of Nickel‐Based Catalysts | A set of nickel‐based catalysts was designed for testing its performance of methanation of synthesis gas (syngas) in a three‐stage, fixed‐bed reactors‐in‐series system. Process input feed stream ratios were simulated by reflecting the requirements for the ratio of H 2 /CO and steam/CO and an approximation of the extent of methanation that needs to be accomplished in each reactor stage. The content of active nickel species in the catalyst increased with the reactor stage sequence, and consequently, syngas conversion and methane yield increased progressively as well, due to the reaction kinetics and thermodynamics of syngas methanation. In parallel, the catalyst preparation method was varied in accordance with the reaction conditions and requirements of each reactor stage. For the catalysts in the first and second reactor stages contacting with the feeds of high and medium reactant concentrations, nickel and cerium precursors were deposited onto commercial alumina pellets by impregnation, followed by drying and calcination to form NiO‐CeO 2 /Al 2 O 3 . Nickel content increased from 5 wt% for the first stage catalyst to 10 wt% for the second stage catalyst, while cerium content was unchanged at 5 wt%. For the third stage catalyst contacting with a feed consisting of lower reactant concentration and having a higher nickel content, the nickel precursor was deposited onto titania (anatase) powder by impregnation, forming NiTiO 3 after calcination, followed by deposition of the cerium precursor onto the mixed oxide by impregnation. Cerium‐deposited NiTiO 3 powder was then physically mixed with alumina powder before being pelletized to a desired size. The recipes of these nickel‐based catalysts were effective in avoiding the formation of inactive NiAl 2 O 4 species during catalyst preparation and suppressing thermal sintering and coking of catalyst during methanation. Each catalyst prepared in this study was active for syngas methanation by exhibiting excellent CO conversion and methane yield in the temperature range of 623–723 K, while catalyst activity slightly decreased at 773 K. Stability of each catalyst was maintained at 623 K for 100 h under the reaction conditions simulated in each reactor stage. Syngas methanation was also run for alternate operation scenarios with different sequences of catalysts and higher space velocities, resulting in different syngas conversions from each reactor stage. The catalyst sequence for these additional works used the nickel‐based catalyst of 5 wt% nickel content in both the first and the last reactor stages, with the same catalyst of 10 wt% nickel content placed in the middle reactor stage. | 10.1155/joch/2512756 | January 2026 | CO conversion | |
