N-doped biomass-derived porous carbon (N/C) with a 3D framework and large specific surface area was obtained by carbonizing bagasse biomass waste with melamine as nitrogen source. The obtained N/C has macroporous structures, rich mesoporous and microporous structures. The multi-grade pore structure can not only increase the specific surface area, b...

Nitrogen self-doped graphene (N/G) nanosheets were prepared through magnesiothermic reduction of melamine. The obtained N/G features porous structure consisting of multi-layer nanosheets. The samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectr...

Nitrogen/sulfur co-doped disordered porous biocarbon was facilely synthesized and applied as anode materials for lithium/sodium ion batteries. Benefiting from high nitrogen (3.38 wt%) and sulfur (9.75 wt%) doping, NS1-1 as anode materials showed a high reversible capacity of 1010.4 mA h g⁻¹ at 0.1 A g⁻¹ in lithium ion batteries. In addition, it als...

We report a strategy for the preparation of three dimensional porous carbon materials by activation of different biomass wastes. The three-dimensional porous carbon material has a multi-layer pore structure of large pores, mesopores and small pores. They are arranged in a bridging manner and the multi-layer pore structure can also achieve good cond...

Superhydrophobic surface with biomimetic micro/nanostructures was prepared in this study. The mammillaria-herrerae-like microspheres, carnation-like microclusters and carnation-petal-like nano-slices of biomimetic micro/nanostructures on magnesium alloy surface can create a stable superhydrophobic surface, which is similar to the “lotus leaf” struc...

A simple, one-step method has been developed to construct a corrosion-resistant bionic superhydrophobic surfaces by solve-thermal process in an ethanol and water solution containing stearic acid. Superhydrophobic surface with biomimetic micronanostructures was prepared in this study. The Mammillaria herrerae-like microspheres, carnation-like microc...

Hollow silica microspheres with holes of tunable numbers and sizes on the shell wall were prepared in this study. Clusters with positively charged polystyrene (PS) microspheres as the central spheres (CSs) and negatively charged PS spheres as the "halo" spheres (HSs) were formed via electrostatic interactions and utilized as a template. In the subs...
