“…A comparison of textural properties was made and summarized in Table 2 between the currently obtained results for MCM-48 and RHA and different properties for mesoporous silica having the same porous structure reported in previous works [4,14,20,22,[49][50][51]. The SA of the current MCM-48 was 1360.14 m 2 /g which was in the same magnitude as the reported values for MCM-48 [14,20,22], and MCM-41 [49].…”

“…The Vp value of the current MCM-48 was 1.030 cm 3 /g, which was higher than the reported values for MCM-48 [14,20,22], MCM-41 [49], SBA-15 [50], and mesoporous silica-alumina [49]. Although, the Vp for the current RHA (0.292 cm 3 /g) was in the same range as the previously prepared RHA [4] and lower than the reported RHA obtained from the different origin [51].…”

“…Silica is an inorganic chemical compound plentifully available in the earth incrustation [1]. Still, despite being abundant, silica is generally made by way of synthesis for use mainly in the preparation of different types of adsorbents [2][3][4] and catalysts [5][6][7][8][9][10][11][12][13][14][15] used in chemical applications. Silica generally exists as alkoxysilane compounds, which can harm health.…”

“…Agricultural waste is one of the most critical renewable silica sources, which are low-cost sources of natural silica like rice husk, rice straw, corn cobs, and bagasse [16,17]. Rice husk ash (RHA) is rich in amorphous silica (SiO2) and other metallic contaminants, which can be obtained after burning rice husk [4,18] and used to make siliconbased products [19]. MCM-48 is a nanostructured mesoporous material that belongs to the M41S family (mesoporous silica).…”

This work studied the textual properties of the MCM-48 and rice husk ash using nitrogen adsorption-desorption at constant low temperatures. According to the International Union of Pure and Applied Chemistry, the adsorption-desorption isotherm proved that the studied materials have a mesoporous structure with type IV. The obtained results of Langmuir, Freundlich, and Brunauer-Emmett-Teller isotherm models showed that the nitrogen adsorption followed Brunauer-Emmett-Teller isotherm. The found adsorption capacity and surface area values for MCM-48 were higher than those values for rice husk ash. Based on the Kelvin equation, Barrett, Joyner, and Halenda model was used to determine pore size distribution, pore diameter, and average pore volume for the adsorbents. The pore size distribution for MCM-48 was narrower than rice husk ash, pore diameter for MCM-48 was less than rice husk ash, and average pore volume for MCM-48 was higher than the value of average pore volume for rice hush ash. The comparison study results between the properties and those previously published for mesoporous materials indicated a convergence in the surface area of MCM-48 and pore volume. Moreover, the results of the comparison between the properties of rice husk ash showed that the surface area and pore volume were equal or less than those obtained before.

Making Persistent Plastics Degradable

et al. 2023

View full text Add to dashboard Cite

The vastness of the scale of the plastic waste problem will require a variety of strategies and technologies to move toward sustainable and circular materials. One of these strategies to address the challenge of persistent fossil‐based plastics is new catalytic processes that are being developed to convert recalcitrant waste such as polyethylene to produce propylene, which can be an important precursor of high‐performance polymers that can be designed to biodegrade or to degrade on demand. Remarkably, this process also enables the production of biodegradable polymers using renewable raw materials. In this Perspective, current catalyst systems and strategies that enable the catalytic degradation of polyethylene to propylene are presented. In addition, concepts for using “green” propylene as a raw material to produce compostable polymers is also discussed.

This research presents a response surface methodology (RSM) with I‐optimal method of DESIGN EXPERT (version 13 Stat‐Ease) for optimization and analysis of the adsorption process of the cyanide from aqueous solution by activated carbon (AC) and composite activated carbon (CuO/AC) produced by pyro carbonic acid microwave using potato peel waste as raw material. Pyrophosphate 60% (wt) was used for impregnation with an impregnation ratio 3:1, impregnation time of 4 h at 25°C, radiant power of 700 W, and activation time of 20 min. Batch experiments were conducted to determine the removal efficiency of cyanide from aqueous solution to evaluate the influences of various experimental parameters such as contact time, cyanide concentration, initial pH, and dosage of adsorbent on cyanide removal efficiency. The statistical analysis showed that the quadratic model was significant. The model very low probability value (p‐value < 0.0001) for activated carbon and composite activated carbon, and the analysis of variance showed a high coefficient of specification values of adjusted R2 (model accuracy with observation) and predicted R2 (model accuracy without observation). The optimum conditions suggested by the model for the process variable were 160 min, pH = 10, 10 mg/L, 0.1 g/50 mL, for time, pH, concentration, activated carbon, and composite activated carbon dose, respectively. The maximum removal efficiency at these conditions was 98.2% for AC and 99.35% for CuO/AC. The equilibrium adsorption data obtained were analyzed by Langmuir and Freundlich isotherm models and results showed that it was better described by the Freundlich model. Likewise, the data of adsorption kinetic was analyzed using two models: pseudo‐first‐order and pseudo‐second‐order. The results showed that adsorption kinetics was well performed by the pseudo‐second‐order model.
