ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

The adsorption of CO2 was investigated on monometallic and bimetallic activated carbon (PAC) prepared from apricot waste. Metals such as Zn, Ni, Ce, Cu were impregnated onto PAC at varying ratios. Scanning electron microscopy images revealed grain-like particles flower-like layers due to the accumulation metals. N2 sorption analysis (BET) showed an increase in surface area 756.95 m2/g after modification with Zn. For adsorbents, addition Ce resulted areas 753.95 731.91 m2/g, respectively. Pore size distribution indicated presence micropore channels 1-2 nm range for both adsorbents. tests demonstrated that metal impregnation enhanced capacity. 0.5Ce/0.5Zn/PAC sample exhibited highest capacity, reaching 4.25 mmol/g 0 °C 2.77 25 °C. heat 0.5Ce0.5Zn/PAC ranged 31.4 41.3 kJ/mol, suggesting is predominantly physical. A two-cycle regeneration test a reduction uptake ranging 5.1 9.7%, indicating high adsorbent stability. also selectivity over N2. Kinetic studies intraparticle diffusion model best fits experimental data. capture system developed this study shows potential applications outlets production processes gas purification facilities.
