The demand for energy has increased tremendously around the whole world due to rapid urbanization and booming industrialization. Energy is major key achieving an improved social life, but production utilization processes are main contributors environmental pollution greenhouse gas emissions. Mitigation of crisis reduction in (water air) difficulties leading research topics nowadays. Carbonaceous materials offer some best solutions minimize these problems easy effective way. It also advantageous that sources carbon-based economical, synthesis comfortable, applications environmentally friendly. Among carbonaceous materials, activated carbons, graphene, carbon nanotubes have shown outstanding performance mitigating pollution. These three exhibit unique adsorption properties storage, water purification, cleansing their electrical conductivity, large specific surface areas, strong mechanical strength. This paper reviews methods nanotubes, graphene significant treatment, dioxide capture improve sustainability.

Selective adsorption of cationic dyes by layered double hydroxide with assist algae (Spirulina platensis) to enrich functional groups

JCIS Open, Год журнала: 2024, Номер 15, С. 100118 - 100118

Опубликована: Июнь 26, 2024

The present study involved the preparation, characterization, and evaluation of layered double hydroxide (LDH) with assistance algae Spirulina platensis (NiAl-Sp ZnAl-Sp). These materials were investigated for their potential selective adsorption cationic dyes, including rhodamine B, malachite green, methylene blue. adsorbents exhibit a significant level selectivity in capacity to adsorb green comparison other dyes. next parameter was evaluated as Based on Langmuir isotherm model, calculated maximum capacities NiAl-Sp ZnAl-Sp determined be 478.190 mg/g (pH = 4, 50 °C 30 min) 123.457 min), respectively. main processes encompassed not only electrostatic interactions but also hydrogen bonding π-π involving dye amino, hydroxyl, carboxyl functional groups derived from platensis. enhances group LDH. findings this indicate that composite demonstrated stability sorbent green. Furthermore, it observed could utilized up four cycles, there noticeable decrease its capability over time. revealed synthesized high efficacy effluent.

A series of MgAl layer double hydroxide-based materials intercalated with Clitoria ternatea flower extract as photocatalysts in the ciprofloxacin degradation

Chemical Physics Impact, Год журнала: 2024, Номер 8, С. 100587 - 100587

Опубликована: Март 27, 2024

The preparation of MgAl Layer Double Hydroxide (LDH) was performed using the coprecipitation method. Pristine LDH calcined at 500°C to produce Oxide (LDO). two materials were modified via restacking-delaminating bioactive compounds from flower extract Clitoria ternatea (CT) LDH-CT and LDO-CT. Modifications are enhance stability catalyst structure, allowing its higher photocatalytic activities regeneration use. prepared catalysts characterized XRD, FT-IR, UV-DRS, BET, SEM-EDX. XRD diffraction pattern showed that three have typical patterns commonly observed in LDH-based materials. FT-IR spectra confirmed LDO-CT combined precursor has lowest bandgap energy with highest degradation kinetics. BET SEM-EDX characterization shows uniform surface pore size on used ciprofloxacin photodegradation under UV light. optimal dose 5 mg, while pH 5. LDO-CT, LDH-CT, capacity up 73.300%, 65.739%, 71.320%, respectively, within 120 minutes. Repeated use third cycle resulted %R reaching 80.871%, 74.003%, 52.025%, by LDH. Compared pristine LDH, CT intercalated exhibited more excellent stability.
