Characterization analysis of activated carbon derived from the carbonization process of plane tree (Platanus orientalis) seeds

Abstract

In this work, plane tree seed-based activated carbons were characterized in detail for a variety of applications. The particularly important area of application would be in the artificial photosynthesis. After carbonization process of biomass precursor at 650°C, the resulting preliminary activated carbons were activated at various temperatures. The activated carbons were characterized by oxygen functionalities (a particularly important role has ester oxygen groups) which provide a unique microstructure. The chemical compositions of as-prepared activated carbons were analyzed through Fourier transform infrared and Raman spectra as well as gas chromatography–mass spectroscopy analysis, while morphology was observed by scanning electron microscopy analysis. Applied analysis showed that detected graphite mainly becomes uniformly nanocrystalline system. The current study also explored the applicability of carbon material obtained from plane tree seed as a potential gaseous adsorbent. The characterization showed that the tested material contains both mesopores and micropores, and this should be advantageous for the gas sorption process, since mesopores may provide low-resistant pathways for the diffusion of CO2 molecules, while the micropores are the most suitable for trapping of CO2. The sorption process analysis (including adsorption/desorption isotherms behavior) shows indication that the rate-limiting step of CO2 adsorption onto activated carbon is probably governed by diffusion-controlled process, especially at temperatures below 850°C.

Extraction of Lightweight Platanus orientalis L. Fruit’s Stem Fiber and Determination of Its Mechanical and Physico-Chemical Properties and Potential of Its Use in Composites

“…The study by Janković et al, 2018 [ 7 ] aimed to examine a potential solid sorbent for a sorption process for harmful gases like CO 2 ; the purpose of the study was to choose experimental techniques for the characterization analysis of raw and pyrolyzed samples of plane tree ( Platanus orientalis L.) seeds and to assess the results. A study by Dodevski et al, 2020 was reported to characterize and analyze the activated carbons produced by the horizontal tubular reactor-based pyrolysis of plane tree seeds [ 8 ]. As they stated, since woody-based biomass and wood charcoals can also be used for cadmium adsorption, their research is significant.…”

Adsorption of crystal violet on activated bamboo fiber powder from water: preparation, characterization, kinetics and isotherms

“…Peak D indicates that the samples have amorphous C atoms with structural defects, which represents the characteristic peak of disordered carbon; peak G indicates that the C atom SP 2 of the sample is hybridized and represents the characteristic peak of ordered graphite structure. 36,37 The increase in the BAC peak intensity ratio ( I D / I G ) indicated that the aromatic structure with high stability increased; the activation process of KOH increased the structural defects of the activated carbon and deformed its carbon layer, which can effectively transport ions and improve the adsorption performance of the activated carbon. 38…”

Striking performance of plasma-synthesized carbon from Prosopis juliflora in a supercapacitor application

“…This is expected to play a major role in bringing up the packing density, thus reflecting in power density. According to Tuinstra and Koenig Law, the I D /I G ratio is inversely proportional to the cluster diameter or size of the cluster (L a ) [36]. The relation between cluster size and I D /I G is given below:…”
