3D-triptycene based microporous polymer as electrocatalyst for hydrogen evolution reaction

A rapid method of synthesizing nanoflowers made of nanoflakes of nickel molybdate (NiMoO) directly on nickel foam (NF) through an aerosol-assisted chemical vapor deposition (AACVD) process is disclosed. The nickel molybdate nanoflowers were grown on NF by varying the deposition time for 60 and 120 min at a fixed temperature of 480° C. and their efficiency was investigated as oxygen evolution reaction (OER) catalysts in 1 M KOH electrolyte. The NiMoOnanoflowers of NF obtained after 60 minutes of AACVD process showed OER performance with lowest overpotential of 320 mV to reach standard current density of 10 mA cm. The catalyst continuously performed the OER for 15 h, signifying its prominent stability under electrochemical conditions.

Metal-free photocatalyst and a method of preparation thereof

A method of water uptake is provided. The method includes contacting a hydrogen-bonded organic framework (HOF) with water to form a mixture where the HOF comprises hydrogen bonded units of trimesic acid and guanazole. The HOF has a sheet structure, where the sheets form an intercrossed macroporous network with pores on a surface. The HOF absorbs at least a portion of the water in the mixture.

Hydrogen-bonded organic framework (HOF) for water uptake

A hydrogen-bonded organic framework (HOF) and a method of making the HOF. The HOF has at least one amine substituted organic linker and at least one carboxylic acid-based organic linker. The HOF is prepared by dissolving the linkers separately in water and mixing the aqueous solutions, without using any organic solvents, additional catalysts, or any other reagents.
