    “…In this study, hollow ZnFe(2)O(4) nanospheres were successfully synthesized by a solvothermal precipitation method firstly; based on this, a C shell precursor phenolic resin was coated on the ZnFe(2)O(4) hollow nanospheres' surface by an in situ oxidative polymerization method, and then ZnFe(2)O(4)@C was obtained by high-temperature calcination. Samples were characterized by SEM, TEM, XRD, XPS, BET, VSM, VNA. …”

    “…Interestingly, these two different titanium active species in the samples could be constructed through calcination or not in the same synthesis process. A possible formation mechanism was investigated in detail; it indicated that the hollowing treatment of TS-1 in the first step was conducive to the construction of the new superior active sites in the samples, and there was a synergistic effect on the formation of these active sites between TPAOH and TEOS in the second step of the synthesis process. …”

    “…The composites are achieved via a facile two-step method, i.e., melamine–Na(+) ion exchange reaction in the cage of the zeolite and subsequent calcination. BET measurement and transmission electron microscopy (TEM) confirm that the g-C(3)N(4) is encapsulated in zeolite-Y, and the polymerization degree can be controlled by the melamine contents exchanged with Na(+) in the cages of zeolite-Y. …”

    “…Bi(2)O(3)/g-C(3)N(4) nanoscale composites with a Z-scheme mechanism were successfully synthesized by high temperature calcination combined with a hydrothermal method. These synthesized composites exhibited excellent photocatalytic performance, especially the 40 wt% Bi(2)O(3)/g-C(3)N(4) composite, which produced about 1.8 times the CO yield of pure g-C(3)N(4). …”
