Micro-mechanism of multi-pathway activation peroxymonosulfate by copper-doped cobalt silicate: The dual role of copper

The synergistic effect of PMS activation by LaCoO3/g-C3N4 for degradation of tetracycline hydrochloride: performance, mechanism and phytotoxicity evaluation

“…S6(a) and (b) (ESI †), the phase structure of the catalyst did not change significantly before and after the reaction. 69 Moreover, the SEM images also indicated that both the fresh and used material surfaces maintained the nanosheet-like structure of LaCoO 3 /g-C 3 N 4 as shown in Fig. S6(c) and (d) (ESI †), which demonstrated the stability of the catalyst structure.…”

Manipulating the Cobalt Species States to Break the Conversion–Selectivity Trade-Off Relationship for Stable Ethane Dehydrogenation over Ligand-Free-Synthesized Co@MFI Catalysts

“…This uniform distribution of Co species led to Co@MFI showing a higher XPS peak intensity than Co/MFI at the same Co contents (Figure b). The peak at 781.8 eV with its satellite at about 787.7 eV suggests that divalent Co­(II) species existed in Co@MFI. , However, the binding energy (BE) of the peak was relatively high, which was much similar to but slightly lower than that (782.3 eV) in a synthesized cobalt silicate (the purple line in Figure b). , The peak at 780.0 eV showed the main presence of trivalent Co­(III) species in Co/MFI same as that for bulk Co 3 O 4 (Figure S5a). , By comparison, Co@MFI contained little trivalent Co­(III) species or CoO x clusters.…”

“…In comparison to the Co@MFI catalyst, Fe@MFI, Ni@MFI, and P-modified CoP@MFI catalysts were also prepared. For comparison, a kind of cobalt silicate (Co 2 SiO 4 ) was also hydrothermally synthesized without TPAOH, according to a published work …”

“…For comparison, a kind of cobalt silicate (Co 2 SiO 4 ) was also hydrothermally synthesized without TPAOH, according to a published work. 74 1, 3, and 6 wt % Co/MFI catalysts were prepared by the incipient-wetness impregnation method. The as-synthesized MFI material was added into a certain amount of Co(NO 3 ) 2 aqueous solution and then placed for 1 h with intermittent stirring.…”

Thermally-enhanced sono-photo-catalysis by defect and facet modulation of Pt-TiO2 catalyst for high-efficient hydrogen evolution

“…A p (4 × 4) supercell containing a 4-layer slab with 64 atoms was modeled for Pt (200) and Pt (111) facets. Moreover, the free energies of hydrogen adsorption and water dissociation were calculated according to the following equation [ 27 , 29 ]: where ∆ E is the binding energy of hydrogen or water, ∆ E ZPE is the difference corresponding to the zero-point energy between the adsorbed atom and the gas phase, and T ∆ S is the entropic contributions ( T being 273.15 K).…”
