A bifunctional CoP/N-doped porous carbon composite derived from a single source precursor for bisphenol A removal

Abstract

Cost-effective and environmentally benign biomass precursor enabled synthesis of CoP/N-doped porous carbon nanocomposite for BPA removal through adsorption and peroxymonosulfate activation.

Development of a novel porous cobalt, phosphorus and nitrogen co-doped carbonaceous coating by phosphiding ZIF-67 grown on nitinol fiber for selective solid-phase microextraction of polycyclic aromatic hydrocarbons from water samples

“…These unique structure and properties make ZIF-67 a promising precursor and sacricial template for the fabrication of porous N-doped carbonaceous coatings with superior adsorption performance. 14,15 Owing to the synergetic hydrophobic, hydrophilic and Lewis acid-base interactions of the obtained carbonaceous coating with different analytes, 16 the in situ fabrication of a highly stable and porous ZIF-67-derived carbonaceous material as a potential ber coating for SPME is greatly desired. Furthermore, the surface adsorption performance can be tailored by surface morphology, composition and doping aer annealing.…”

“…14 In addition, Li et al prepared a cobalt phosphide and nitrogen-containing carbon composite as an electrocatalyst via low-temperature phosphorization of ZIF-67 with sodium hypophosphite. 12 These ZIF-derived carbonaceous materials have the ability to adsorb organic compounds, 15 and are potential SPME coating materials. 16 To improve the adsorption performance of carbonaceous coatings in practical SPME applications, porous multifunctional carbonaceous coatings with superior performance by integrating several components into one were expected.…”

Synergistic advanced oxidation process for enhanced degradation of organic pollutants in spent sulfuric acid over recoverable apricot shell-derived biochar catalyst

“…The COD content of the reaction solution was measured according to the standard methods of HJ/T 399-2007 in China, 23 the TOC content was measured by a TOC-V CPN analyzer (Shimadzu), and the color scale of the reaction solution was determined by the dilution multiple methods. The contents of C, H, S, N elements in spent sulfuric acid and treated sulfuric acid were obtained with a Vario EL III Elementary, and the samples were absorbed by SiO 2 before elemental analysis since they were corrosive.…”

“… 22 Biochar is considered as an alternative catalyst with favorable physicochemical properties, which could be prepared from agricultural residues such as cornstalk, sugarcane bagasse, coconut shell, and apricot shell. 23–25 Especially, biochar with various functions such as waste disposal and wastewater remediation could be obtained through different physical or chemical activation procedures. 26,27 However, the previous studies on biochar mainly concentrated on its adsorption of organic pollutants in wastewater or soil.…”

On-Line Thermally Induced Evolved Gas Analysis: An Update—Part 1: EGA-MS

“…from the nucleic acid were detected by hyphenated thermal analysis to evaluate EGA (TG-MS and TG-IR); also, they were suggested to be responsible for the transformation of phosphate in the precursor to phosphide in CoP. The exhausted sample could also be regenerated by a facile thermal treatment approach [ 74 ].…”
