Nov 25, 2020 · Herein, interface engineering heterojunctions between ZIF-67 and layered double hydroxide (LDH) are designed to enhance the catalytic activity of the OER and the stability of Co-LDH.

Cobalt-based layered double hydroxides (Co-based LDHs) are cost-efficient electrocatalysts toward the oxygen evolution reaction (OER) associated with the conversion of clean and renewable energy.

The Co–Co LDH/C/Ni (OH) 2 nanostructure revealed a high specific capacitance of up to 1426 F g −1 at 1 A g −1 and an outstanding rate capability with 90.2% retention at 10 A g −1 owing to the cooperative effect of the Ni (OH) 2 nanodots and hollow Co–Co LDH/C nanocages.

Nov 1, 2023 · In this work, we present a feasible scheme for fabricating a novel hybrid LDH via in-situ growth the precursor of ZIF-67 (Co-LDH) on the surface of sodium dodecyl benzene sulfonate intercalated MgAl-LDH. The obtained hybrid LDH can improve the compatibility and flame-retardant efficiency of MgAl-LDH for EP system.

Mar 28, 2019 · Herein, a novel strategy involving an in situ transformation of ultrathin cobalt layered double hydroxide into 2D cobalt zeolitic imidazolate framework (ZIF-67) nanosheets grafted with 3D ZIF-67 polyhedra supported on the surface of carbon cloth (2D/3D ZIF-67@CC) precursor is proposed.

Apr 1, 2020 · Herein, a network of curly-edged CoFe-layered double hydroxide (LDH) nanosheets was grown on Ni foam via a one-pot hydrothermal synthesis route. We studied the stepwise morphological evolution and electrochemical performance of CoFe-LDH during variable hydrothermal reaction conditions.

Aug 23, 2023 · Herein, we successfully synthesized a high-density ultrafine Au cluster (∼0.7 nm)-doped cobalt-layered double hydroxide nanocage (Au/Co-LDH) photocatalyst through an in situ redox strategy to explore the structure–activity relationship in the CO 2 reduction system.

Mar 27, 2024 · The synthesis of carbon nanotubes (CNTs) by water-assisted chemical vapor deposition using Co-containing layered double hydroxides (Co-LDH) as catalyst precursors and the catalytic mechanism of Co-LDH catalyst precursors during CNT synthesis were investigated.

Mar 1, 2019 · To solve the agglomeration of layered double hydroxides (LDH) for improving their supercapacitor performances, Co, Mn-LDH nanoneedle arrays grown on Ni foam (Co, Mn-LDH@NF hybrid) was fabricated via a one-step hydrothermal strategy.

ZIF-67@Co-LDH yolk–shell heterostructures are successfully synthesized by successive increase in Co 2+ concentration in the methanolic solution of Co 2+ and 2-methylimidazole (Hmim).
