Catalytic Removal of Aqueous Contaminants on N-Doped Graphitic Biochars: Inherent Roles of Adsorption and Nonradical Mechanisms

Environmental Science & Technology, Journal Year: 2018, Volume and Issue: 52(15), P. 8649 - 8658

Published: July 20, 2018

Environmentally friendly and low-cost catalysts are important for the rapid mineralization of organic contaminants in powerful advanced oxidation processes (AOPs). In this study, we reported N-doped graphitic biochars (N-BCs) as efficient peroxydisulfate (PDS) activation degradation diverse pollutants water treatment, including Orange G, phenol, sulfamethoxazole, bisphenol A. The at high annealing temperatures (>700 °C) presented highly nanosheets, large specific surface areas (SSAs), rich doped nitrogen. particular, N-BC derived 900 °C (N-BC900) exhibited highest rate, which was 39-fold 6.5-fold that on N-BC400 pristine biochar, respectively, N-BC900 surpassed most popular metal or nanocarbon catalysts. Different from radical-based N-BC400/PDS via persistent free radicals (PFRs), singlet oxygen nonradical pathways (surface-confined activated persulfate–carbon complexes) were discovered to dominate N-BC900/PDS. Moreover, adsorption organics determined be key step determining reaction revealing pre-adsorption reactants significantly accelerated pathway. This study not only provides robust cheap carbonaceous materials environmental remediation but also enables first insight into biochar-based catalysis.

Adsorption Behaviors of Organic Micropollutants on Zirconium Metal–Organic Framework UiO-66: Analysis of Surface Interactions

ACS Applied Materials & Interfaces, Journal Year: 2017, Volume and Issue: 9(46), P. 41043 - 41054

Published: Oct. 27, 2017

Herein, we studied the adsorption behaviors of organic micropollutants, such as anticonvulsant carbamazepine (CBZ) and antibiotic tetracycline hydrochloride (TC), on zirconium metal-organic framework UiO-66 in water. The maximum capacities CBZ TC were 37.2 23.1 mg·g-1 at 25 °C, respectively. isotherms kinetics well described by using Langmuir model pseudo-second-order model, respectively, adsorptions are endothermic reactions. decreased with increase solution pH. presence humic acid could improve UiO-66, but K+ ion inhibited their obviously. In addition, Ca2+ Al3+ ions also suppressed UiO-66. competitive suggested that sites for different from those TC. surface interactions between two micropollutants demonstrated powder X-ray diffraction, Fourier transform infrared (FT-IR) spectra, scanning electron microscopy, nitrogen adsorption/desorption isotherms, photoelectron (XPS) spectra. characterizations showed is mainly a physisorption, hydrophobic effect played crucial role during CBZ; meanwhile weak π-π donor-acceptor interaction electrostatic attraction existed. However, chemisorption; addition to strong forces, nitrogenous groups an important role, which can replace carboxylic coordinated Zr-O clusters. obtained results will aid us comprehend expand application sorbent removal pollutants
