Special Issue Information

Dear Colleagues,

As a carbonaceous adsorbent with good performance, activated carbon has a developed pore structure, large specific surface area and high mechanical strength, and is widely used in the field of wastewater and waste gas purification. However, in recent years, the demand for carbonaceous adsorbents has gradually increased, and the prices of carbonaceous adsorbents prepared from traditional raw materials such as wood and coal have also risen. Therefore, the preparation of high-performance carbonaceous adsorbents from cheap raw materials has become a research hotspot.

This Special Issue aims to provide a platform to publish new advances in carbonaceous adsorbents. The focus of these developments may be related to the application of advanced processing techniques in the synthesis, manipulation and functionalization of carbonaceous materials and the detailed chemical and functional characterization of raw materials and composites, optimizing the properties of materials and composites for high-tech applications. I cordially invite any researchers willing to contribute to the field to submit their work to this Special Issue, "Preparation of Carbonaceous Adsorbent and Study of Its Interface Behavior".

I look forward to receiving your contributions.

Dr. Ranwen Ou
Guest Editor

In Brazil, a significant part of the biomass is unused, contributing to environmental pollution. The tannin industry commonly extracts tannins from the bark of Acacia mearnsii or black wattle, leaving a significant residue of 70% (w w−1). This study investigates the conversion of black wattle bark into a porous carbonaceous material to efficiently remove organic pollutants. Using ZnCl2 as a chemical activation reagent, the experiments varied the impregnation time, carbonization rates, and temperatures. Additional experiments aimed to increase the specific surface area (SSA). X-ray diffraction (XRD) analysis showed the formation and removal of ZnO, which increased porosity. Scanning electron microscopy (SEM) showed an irregular morphology with pores. Fourier-transform infrared (FTIR) spectroscopy indicated characteristic bands, and electron paramagnetic resonance (EPR) detected organic free radicals. The SSAs exceeded 1000 m2 g−1, averaging 1360 m2 g−1, with a maximum of 1525 m2 g−1. Micropores (1.4 nm) were consistent. The structure of the material and the high SSA suggest a potential for efficient removal of aromatic impurities by π–π interactions. This approach addresses the issue of biomass waste, provides a solution for environmental remediation, and represents a transformative strategy for biomass utilization. Full article
