Porous carbon particles (PCPs) prepared from sucrose via the hydrothermal method and its modified forms with polyethyleneimine (PEI) as PCP-PEI were used templates in situ metal nanoparticles M@PCP M@PCP-PEI (M:Co, Ni, or Cu), respectively. The composites catalysts hydrolysis of NaBH4 NH3BH3 to produce hydrogen (H2). amount Co within Co@PCP-PEI structure was steadily increased multiple loading/reducing cycles, e.g., 29.8 ± 1.1 mg/g at first cycles 44.3 4.9 after third cycles. catalyzed 120 min 251 1 mL H2 production a 100% conversion ratio 3.8 0.3 mol H2/(mmol cat·min) turn-over frequency (TOF) lower activation energy (Ea), 29.3 kJ/mol.

ABSTRACT This annual review outlines the progress of carbon capture, utilization, and storage (CCUS) technologies in 2024. As human‐induced CO 2 emissions continued to rise, year presented critical challenges. Notably, 2024 was hottest on record first which global temperatures exceeded preindustrial levels by more than 1.5°C, driving intensified efforts advance CCUS. Scientific interest CCUS grew significantly, with number related publications increasing 11.4% compared 2023, reaching 53,970. The total operational commercial facilities also expanded, rising 16.3% a 50. In political area, governments introduced targeted policies accelerate adoption, focusing economic investment specific implementation requirements.

Carbon dioxide (CO2), one of the primary greenhouse gases, plays a key role in global warming and is culprits climate change crisis. Therefore, use appropriate CO2 capture storage technologies significant importance for future planet Earth due to atmospheric, climate, environmental concerns. A cleaner more sustainable approach using porous materials, membranes, amine-based sorbents could offer excellent possibilities. Here, sucrose-derived carbon particles (PCPs) were synthesized as adsorbents capture. Next, these PCPs modified with branched- linear-polyethyleneimine (B-PEI L-PEI) B-PEI-PCP L-PEI-PCP, respectively. These their PEI-modified forms then used prepare metal nanoparticles such Co, Cu, Ni situ M@PCP M@L/B-PEI-PCP (M: Ni, Cu). The presence PEI on PCP surface enables new amine functional groups, known high ability. structure may be catalyst convert captured into useful products, e.g., fuels or other chemical compounds, at temperatures. It was found that has larger area higher capacity 32.84 m2/g 1.05 mmol CO2/g adsorbent compared L-PEI-PCP. Amongst metal-nanoparticle-embedded PEI-PCPs (M@PEI-PCPs, M: Cu), Ni@L-PEI-PCP have capacity, 0.81 adsorbent, 225 m2/g. data are they will steer studies conversion fuels/chemicals.
