Thermally constructed stable Zn-doped NiCoO alloy structures on stainless steel mesh for efficient hydrogen production via overall hydrazine splitting in alkaline electrolyte.

Hydrogen has a high energy density of approximately 120 to 140 MJ kg, which is very high compared to other natural energy sources. However, hydrogen generation through electrocatalytic water splitting is a high electricity consumption process due to the sluggish oxygen evolution reaction (OER). As a result, hydrogen generation through hydrazine-assisted water electrolysis has recently been intensively investigated.

Exfoliation of 2D materials by saponin in water: Aerogel adsorption / photodegradation organic dye.

The biggest challenge for the paint industry is to clean the contaminated waste dye solution before it released into the water or to reuse it to create new paint and to protect the water from environmental pollution. Here in this work, exfoliating layered transition metal dichalcogenide materials prepare to the exfoliated 2D materials thin sheets in water with the assistance of natural saponin. Then, the three-dimensional (3D) MoS-aerogel composite was synthesized by using greenway exfoliated two-dimensional (2D) MoS thin sheets to form MoS-aerogel composite.
