“…The mechanical strength of ZVI/Mn-C-11 was highest at 17.5 N/bead, which can prevent the spherical catalyst from cracking during the entire reaction process. In addition, the average pore size of all samples was 3-4 nm in mesopore size, which was consistent with previously reported results [38]. The XRD patterns of ZVI/Mn-C samples are shown in Figure 2.…”

“…In view of the above problems, the phenol resin (PF)-based carbon spheres with a millimeter scale, smooth surface and high sphericity are more competitive for heterogeneous Fenton processes due to its facile preparation and ease of separation. According to a previous paper [38], spherical activation carbon with a diameter of about 2 mm can be prepared by an ammonium alginate (ALG)-assisted sol-gel method using PF as the carbon precursor, which can be applied to the preparation of a spherical ZVI/Mn-C bimetallic catalyst. The prepared ZVI/Mn-C catalysts showed the following advantages: (1) it is facile and effective to introduce the metals with uniform dispersion into the carbon spheres via a carbothermic method; (2) the synergistic effect of ZVI and Mn species immobilized on activated carbon could be helpful to achieve a higher activity and extend the pH range in the heterogeneous Fenton reaction; (3) the reacted ZVI/Mn-C catalysts could be easily separated from wastewater.…”

The heterogeneous Fenton-like reaction has been receiving increasing attention for its inexpensiveness and high efficiency in water treatment. In this study, a novel strategy was proposed for preparing spherical ZVI/Mn-C bimetallic catalysts with a high activity for a Fenton-like reaction by using the ammonium alginate assisted sol–gel method coupled with a carbothermic reduction. The results showed that the obtained ZVI/Mn-C spheres had a uniform size, smooth surface and good sphericity, and the particle size of ZVI was limited to about 30 nm by the carbon layer. Among all catalysts, the ZVI/Mn-C-31 catalyst exhibited the highest phenol degradation efficiency in the Fenton-like process, and almost 100% phenol degradation efficiency was achieved under neutral pH at room temperature within 5 min. Moreover, the ZVI/Mn-C-31/H2O2 system showed a 100% degradation efficiency for removing a wide range of aromatic pollutants, including catechol, resorcinol and o-nitrophenol. Moreover, the radicals-scavenging experiment illustrated that the ·OH played a key factor in mineralizing the organic matters, and the ·O2− generated from the MnO-H2O2 system accelerated the conversion rate of ferric iron to ferrous iron. Due to the synergistic effects between ZVI and MnO, the ZVI/Mn-C-31 catalyst performed excellently in the Fenton-like reaction at an extended pH range.

“…This material can be utilized for the storage of gases such as CO2, CH4, and H2. Mesoporous spherical activated carbon can be synthesized using a soluble low molecular weight phenolic resol using a sol-gel reaction under ammonium alginate (Wang et al, 2018). This modification improves the isobutane conversion and isobutene selectivity.…”

The dyes of the textile dyeing industry wastewater are harmful to humans and the environment. They should be treated before discharging into the environment. The adsorption using the spherical activated carbon can be effective to reduce the dyes. The spherical activated carbon of 3-7 µm in diameter was successfully prepared from the waste bagasse liquid using the hydrothermal method. The activation of this carbon was carried out using the KOH solution. The optimum pH and contact time were achieved in 2 and 200 min, respectively. Adsorption kinetic for RhB on activated spherical carbon follows the second-order kinetics and its adsorption mechanism follows the Langmuir isotherm. The maximum adsorption capacity of spherical activated carbon to Rhodamine B was achieved in 64.52 mg/g.
