Abstract Catalytic hydrogenation of CO 2 into CH 4 is an effective method to convert waste and green hydrogen clean fuel on a large scale. However, the viability such process largely relies development highly active heterogeneous catalysts. Here, tailored methanation catalyst, Co nanoparticles immobilized porous N‐doped carbon matrix, prepared by carbonization cobalt‐based layered zeolitic imidazolate framework (ZIF−L) material under argon atmosphere. This catalyst displays specific activity 22.3 mol CH4 /g cat .min at 350 °C, significantly outperforming similar derived from more conventional ZIF‐67 (11.7 .min). explained stabilization small (∼20 nm) presence abundant medium‐strength basic sites related nitrogen doping in ZIF−L. Notably, new shows high stability; no deactivation observed up 60 hours stream.

Developing a highly efficient photocatalytic system is sustainable approach for generating clean hydrogen to address the proliferating consumption of primary energy sources. In this study, trimetallic NixCoyAlz LDH with controlled surface morphology was designed and incorporated g-C3N4 construct S-scheme electron transfer system. The coeffects regulating cationic composition dominance Ni, Co, Al as active centers in framework were investigated. Configuring M2+/M3+ interaction results variations band gap value photonic characteristics, influencing its performance efficiency light absorption capability. optimal design Ni1Co1Al1 exhibited exceptional photochemical stable structural formation enhanced reduction ability, significantly improving production. electronic structures enable construction an binary nanocomposite. charge offers spatial separation photogenerated charges suppresses their recombination, resulting maximal production, reaching up 338 μmol g–1 h–1 10–2NiCoAlCN. activity test over consecutive cycles revealed gradual yield, demonstrating good chemical stability. This study explored intercorrelation between effects on properties LDH, which can serve valuable insight further research field.

Review of Carbon Capture and Methane Production from Carbon Dioxide

Atmosphere, Год журнала: 2022, Номер 13(12), С. 1958 - 1958

Опубликована: Ноя. 24, 2022

In the last few decades, excessive greenhouse gas emissions into atmosphere have led to significant climate change. Many approaches reducing carbon dioxide (CO2) been developed, with capture and sequestration (CCS) techniques being identified as promising. Flue that produce CO2 are currently captured, sequestered, used on a global scale. These offer viable way encourage sustainability for benefit of future generations. Finding ways utilize flue has received less attention from researchers in past than storage. Several problems also need be resolved field technology, including those relating cost, storage capacity, reservoir durability. Also covered this research is current technology. This study proposes sustainable approach combining CCS methane production feedstock, making technology more practicable. By generating renewable energy, provides several benefits, reduction increased energy security. The conversion recommended practice because many benefits methane, which make it potentially useful pollution promoting sustainability.
