“…In another method, biomass is pyrolyzed in the absence of oxygen (in the presence of N 2 or Ar) to form biochar (carbonaceous material). 88 The carbonization temperature has a direct influence on the surface of biochar. The catalyst synthesized at low carbonization temperature (400–600 °C) has a significant impact on the structure.…”

“…The biosensor was able to detect cancer cells with high sensitivity and specificity. 33 ZNSs have also been used to develop scaffolds for tissue engineering applications. The high surface area and biocompatibility of ZnO nano-architectures make them ideal for promoting cell adhesion and proliferation.…”

“…The carbon-rich material (BC) shows promising activity to adsorb inorganic and organic pollutants from wastewater. Moreover, biochar has unique surface characteristics, such as increased porosity, huge surface area, and functional group abundance, which all promote the rapid abatement of pollutants 14 . Biochar supports other metal oxide catalysts because of abundant functional groups, chemical conductivity, and stability 15 .…”

In this work, the author developed Ca4Fe9O17/biochar (CFB) via a green method through a facile co-precipitation procedure involving egg shells as calcium precursor and investigating its performance in single as well as binary solution of methylene blue (MB) and rhodamine B (RhB). The CFB nanocomposite was characterized by XRD, SEM, TEM, XPS, Raman, FTIR, BET, and VSM. ESR studies show the presence of hydroxyl (·OH) and superoxide (O2·¯) radicals, which are primary radical species for pollutant degradation. The average crystalline size of CFB nanocomposites was found to be 32.992 nm using XRD, whereas TEM analysis indicates a particle diameter of 35–36 nm. The degradation efficacy of MB and RhB dyes was achieved at 99.2% and 98.6%, respectively, in a single solution, whereas 99.4% and 99.2%, respectively, in a binary solution within 36 min. Additionally, an iron cluster was formed during the degradation process of MB dye. The degradation of organic contaminants and generation of iron clusters from the degraded dye products were both expedited by the remarkable extension effect of the Ca4Fe9O17 in the CFB nanocomposites. The three processes were achieved using CFB nanocomposite: (1) the advanced oxidation process; (2) degradation of MB and RhB dye in single as well as binary solution with enhanced efficiency, (3) the production of the iron cluster from degraded products. Thus, these three steps constitute a smart and sustainable way that leads to an effective effluent water treatment system and the generation of iron clusters preventing secondary pollution.
