A versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxide and oxide nanospheres as catalytic reactors

Toward Rational Design of Ordered Heterostructures for Energy and Environmental Sustainability: A Review

“…Sacrificial templating method can convert solid-state nanomaterials into heterostructure that may inherit the chemical composition, size, shape, and pore structure from templates, [89] thereby creating intriguing heterostructures that can hardly be prepared by wet chemistry. [90] To date, existing templates include metal oxides, [91,92] metal hydroxides, [67,93] metal sulfide, [94,95] MOFs, [83,[96][97][98] carbon materials, [99] polyoxometallate, [100,101] etc., as discussed in the following.…”

Solvent-free oxidation of benzyl C–H to ketone with Co–Ni layered double hydroxide as the catalyst and O2 as the sole oxidant

“…[13][14][15][16] Noble-metal catalysts realize the oxidation of ethylbenzene through the activation of the C-H bond, while transition-metal oxides such as CeO 2 , MnO 2 and Co 3 O 4 can promote the catalytic autoxidation of ethylbenzene by activating molecular oxygen. [17][18][19][20] The considerable catalytic activity of transition-metal oxide catalysts could only be obtained using N-hydroxyphthalimide (NHPI) as an initiator and special solvent. 21 The Co 3 O 4 dispersed on reduced graphene oxide could realize 84.1% conversion of ethylbenzene and a 96.2% selectivity of acetophenone with NHPI as the initiator and acetonitrile as the solvent.…”

One-Step Synthesis of Hollow CoS2 Spheres Derived from Polyoxometalate-Based Metal–Organic Frameworks with Peroxidase-like Activity

“…The most widely used technique to prepare these hollow spheres is, by far, the template method. 32,33 Therefore, the design of CoS 2 precursors that may also act as templates for the preparation of hollow pure phases is of paramount importance.…”
