SnO2/Zn2SnO4 hollow microspheres with porous shell (HPMSs) were successfully prepared by using ZnSn(OH)6 (ZHS) hollow microspheres (HMSs) as sacrificial templates, which were pre-synthesized via a fast solid-state grinding method combined with subsequent chemical etching process. The obtained samples were characterized by XRD, SEM, TEM, and N2 adsorption-desorption, respectively. Results indicated...
Mesoporous microrods (MPMRs) of α-Fe2O3 were successfully synthesized via a facile and reliable two-step route by using pre-synthesized FeC2O4·2H2O as sacrificial template. The prepared samples were characterized by XRD, FESEM, TEM, and N2 adsorption-desorption, respectively. Results indicated that during the thermal decomposition process, the FeC2O4·2H2O precursor can pass its morphology on to the...
