Molybdocene dichloride intercalation into zirconium phosphate nanoparticles

Preparation of Zirconium Phosphate Nanomaterials and Their Applications as Inorganic Supports for the Oxygen Evolution Reaction

“…This can be confirmed with XRPD as the first diffraction peak at 2θ = 8.6° (d 002 = 10.4 Å) for θ-ZrP, which corresponds to the interlayer distance, shifts towards 11.6° (d 002 = 7.6 Å) when this material dehydrates. Hence, determining if an intercalation was successful is trivial, as the XRPD analysis of a dry intercalation product should yield a first diffraction peak with a distance greater than 7.6 Å [ 14 ].…”

“…Ion-exchange in ZrP occurs at the Brönsted acid groups (P-OH) which are also present at the surface of the nanoparticles, opening another pathway for the modification of this material: surface modification [ 9 , 10 , 11 ]. These composite materials have been used for several applications including photocatalysis [ 12 , 13 ], drug delivery [ 14 , 15 , 16 , 17 ], amperometric biosensors [ 18 , 19 , 20 ], catalysis [ 7 , 21 , 22 , 23 , 24 , 25 , 26 ], flame retardancy [ 27 , 28 , 29 ], and others. We encourage the reader to also see other recent reviews on the topic of the synthesis of ZrP and its applications [ 7 , 8 , 30 , 31 ].…”

Transition Metal-Modified Zirconium Phosphate Electrocatalysts for the Oxygen Evolution Reaction

“…If pure θ-ZrP is dried, dehydration converts it to α-ZrP; therefore, all samples are referenced to the α-ZrP (002) diffraction peak at 2θ = 11.5°, corresponding to an interlayer distance of 7.6 Å [44]. As described in the literature, an intercalation reaction can occur in a stepwise fashion depending on the intercalation energy threshold of the intercalants [45].…”

“…As described in the literature, an intercalation reaction can occur in a stepwise fashion depending on the intercalation energy threshold of the intercalants [45]. During this process, one of three possible patterns can be observed by XRPD for metal-modified ZrP; either (i) a pattern with a peak corresponding to a larger interlayer spacing at lower 2θ values than 11.5° indicating that metal cations were introduced into the interlayer; (ii) a pattern with two distinct peaks-one at approximately 2θ = 11.5° and one that appears at lower 2θ values than the reference peak indicating that a mixed phase is present; and (iii) a pattern with no change in the reference peak, indicating that the cation species is adsorbed on the outer surface of the layered structure rather than being intercalated [44]. Below, the XRPD analysis for all metal-modified ZrP systems is presented.…”

Intercalation of (η5‐Pentamethylcyclopentadienyl)trioxomolybdenum(VI) in a Layered Double Hydroxide

“…Research on the intercalation of organometallic guest molecules into inorganic layered host matrices was kickstarted by Dines with the intercalation of cobaltocene (CoCp 2 , Cp = η 5 ‐C 5 H 5 ) into metal dichalcogenides MX 2 (M = Ti, Zr, Nb, Ta and Sn; X = S, Se) . Since then a large number of bis‐Cp and bis‐arene sandwich complexes (and their ring‐substituted derivatives) and bent metallocenes such as Cp 2 MoCl 2 have been intercalated into a range of host lattices including metal dichalcogenides, MOCl (M = Fe, V, Ti), MPS 3 (M = Mn, Zn, Fe, Ni), β‐ZrNCl, MoO 3 , zirconium phosphate, vanadyl phosphate,, layered silicates,, and layered double hydroxides (LDHs) . In sharp contrast, there are few reports of the incorporation of half‐sandwich “piano stool” complexes within inorganic layered materials, with two examples being [CpRu(benzo‐15‐crown‐5)] + in MPS 3 (M = Mn, Cd, Zn), and [CpMo(CO) 3 CH 2 COO – ] in a Zn,Al LDH …”
