MoS2/CoAl-LDH heterostructure for enhanced efficient of oxygen evolution reaction

Pore size and electronic tuning in cerium-doped CoFe-LDH for the oxygen evolution reaction

“…35 LDH materials have wide application in the areas of catalysis, 31 fluorescence and luminescence processes, 35,36 separation processes, 37 drug delivery, etc. 38 Among them, the LDHs that can promote the OER include nickel-and cobalt-based LDHs, such as NiFe-LDH, 39,40 NiAl-LDH, 41 CoAl-LDH, 42,43 CoMn-LDH, [44][45][46] CoFe-LDH, [47][48][49] and so on. However, the pore sizes of LDHs are usually broad (ranging from 1-80 nm), which limits the number of active sites for catalysis and thus decreases the OER.…”

“…54,58 However, literature reports suggest that doping of other elements in LDH can significantly improve the catalytic performance of the OER. 43 It has been argued that heteroatom doping could modify the electronic structure of the catalyst, which may optimize the adsorption energy of reaction intermediates. [59][60][61][62] The incorporated atoms could act as the active centres toward electrocatalytic reactions, thereby synergistically contributing towards the improvement of the electrocatalytic performance.…”

Enhancement of Hydrogen and Oxygen Evolution Reaction Efficiencies by Coupling a MoS2 Nanoflower with a CoMnCr LDH Nanocube on Nickel Foam

“…The XRD patterns revealed characteristic peaks of CoMnCr LDH@MoS 2 at 11.3, 16.2, 23.3, 35.0, 60.6, and 62.8°, which belong to (003), (002), (006), (012), (110), and (113) planes, respectively. Similarly, CoMnCr LDH showed peaks at 11.4, 23.6, 35.2, 60.5, and 61.9°, which belong to (003), (006), (012), (110), and (113) planes, respectively . The diffraction peaks of CoMnCr LDH@MoS 2 matched well with those of CoMnCr LDH, indicating the successful synthesis of the catalyst.…”

Layered Double Hydroxide Functioned as a Novel Template for the Synthesis of Graphene-Oxide-Like Biochar and Enhanced Electrochemical Performances

“…On the other hand, graphene nucleation density was decreased. 52,53 These two reasons suppressed the formation of structural defects, thus improving graphitization degree. Generally, during a pyrolysis process of biomass, a small biomass fragment, which was similar to 1,4-dicarboxybenzene, volatilized into atmosphere.…”
