A 3D ternary hybrid containing Co_0.85Se nanosheet-array and NiFe-LDH grown on electrochemically exfoliated graphene was synthesized for highly-efficient overall water-splitting.’

Iron–BTC aerogels (BTC= 1,3,5-benzene tricarboxylate) with high permanent porosity and total pore volumes of up to 5.6 cm³ g⁻¹ were obtained in a sol–gel approach followed by supercritical CO₂ drying.

A series of porous carbons (PCs) with adjustable high surface areas and narrow micropore size distributions have been prepared by KOH activation of fungi-based carbon sources. The resulting PCs demonstrate both high CO₂ uptake (5.5 mmol g⁻¹) and high CO₂/N₂ selectivity (27.3) at 273 K and 1 bar, implying their great potential as CO₂ capture sorbents.
